Finally installed the Flowmaster exhaust kit for the Titan. Very happy with the sound and performance. I have the cat back kit #17406. Aluminized steel 70 series muffler, Y-pipe to single in (3"), dual out (2.5"), polished stainless steel embossed rolled tips, all mandrel bends. Bolt on kit replaces the stock exhaust after the resonators. I purchased mine from Summitracing.com for ~$417 with free shipping, they even set it up so the kit was delivered directly from Flowmaster to me (N. Cal to So. Cal). I’ll post a few more pics later but enjoy these for now.

Sound Clip Notes: The stock exhaust rev sound clip and Flowmaster rev sound clip were done with the same recorder, same location/distance, and nearly same RPM revs (+/- 500 rpms). Use these to compare the before/after difference. The Flowmaster exhaust sound clip from the interior was under moderate acceleration up a hill from a stop.

Bet your happy!!! Sounds sweeeeetttttt! Now you'll be suckin up gas to here the exhaust :lol:

thats making me second guess my banks purchase. for some reason i thought it would be a little more raspy. i like it keep the pedal down

Thanks, Caltitan. Can you snap a pic of the y-pipe for me? Looks/sounds great. Any fitment or clearance issues with the install? I like the fact that you have the option of going side or rear exit with this kit.

Nice post Calititan. Didn't you just have a blast doing that. I know I did when I made mine. Good job man.

Nice work CalTitan. I'm still on the fence about getting duals. I'm really worried about the cab noise at cruising speed.

Thank you VERY Much.
I THOUGHT the 70 series would be the right application, but Hearing is Believing! Thanks for the post. Hats Off, From Texas! Yee Haw! LOL!

I'm glad people are enjoying the sound/video clips. Some have been wondering about the cruising noise level (aka "drone"). My stock exhaust had a slight drone when cruising at about 1700-1900 RPMs but it never bothered me and nobody riding with me ever complained. With this Flowmaster system, there is still some drone at about the same rpm range and it is somewhat louder than the stock drone. However, I can still talk in the cab and listen to music as I did before. My wife has remarked that she thought it would be much louder in the cab after hearing how loud it can be from the outside. I have also noticed that if you use the cruise control within that rpm range the exhaust quiets down a bit. If you are looking for an exhaust that is only slightly louder than the stock exhaust, then this system may not be for you. IMO, the 70 series muffler becomes more progressively louder than stock as the RPMs rise. I do know it is not as loud as the 40-series muffler (which I have heard on a Titan). Hope this helps those wondering about this system. Anyone who lives close and wants to hear it need only PM me with a request. I live in Orange County (south) and work in the city of Irvine.

Couldn't stand it anymore......so I ordered the Flowmaster kit a few hours ago from Summit! What can I say....love the sound of my AeroTurbine custom system, but this Flowmaster cat-back has the classic sound I'm looking for and I think may perform slightly better due to a nicer y-pipe and mandrel-bent pipes.

BTW....summit has this kit on back order until 2/23/05, and like Caltitan, my cost was $417 to the door. Now an anxious 4-5 weeks awaits! Aaargh.... Can someone please pass the will power??!

As promised, here are more pics of my Flowmaster exhaust.

I'd personally want to bend a 'crook' on the end of the body side hanger. It looks Too close to the spare - For Impaling!
I KNOW when I drive around a corner EVERYTHING Shifts! If it weren't for my seat belt I'd Fly out the window! LOL

-SeanI still need to call Flowmaster and ask them about this part of the install. I'll post what I find out about it. Maybe their install instructions were written for a crew cab and the space around the spare tire in that area is different.

Sounds Great!!! Am I understanding correctly, that this kit will allow either straight back like your set-up or out the side like the gibson dual extreme? I looked on Flowmasters site and there wasn't much info there.

I looked on Flowmasters site and there wasn't much info there.Yes, the kit comes with both options for dual rear or dual side exits. Here is a diagram of all the parts of the exhaust kit that come from the system.

Did you try the side exiting and not like it or did you just want straight out the back. I think its great you get the choice. Great idea they had there. Let the customer choose. Or even have it one way for a while and switch it up every once in a while.

What's the General Concensus? Is there a particular reason to want it one way over the other?

I like it out the back, It's like saying, "Eat My Exhaust!"
Then when you back your boat down the ramp, you get the "Blub, Blub, Blub" sound!

m4ckThat's just what it was about, having a choice. Personally, I like the look out the back better then the sides and I was thinking that having the sound go out the rear rather than out the side would be slightly quieter in the cab. The consensus is that if you are towing then have them point out the side so that soot does not build up on your trailer. There can also be a chance of exhaust gases entering into an open window in a camper or shell if you have the rear exhaust. The towing I do is for work and it is usually low lying trailers with some type of equipment on them so I'm not worried about soot. I am only going to have the tips and end pipes tack-welded so if I ever want to switch over I can do it easily.

I love the sound of that 70 series flowmaster you put on your truck. I have an 04 Titan SE (galazxy). I cant stop listening to it.

One question, what do you all think about putting a 40 series on the Titan. I dont know too much about mufflers and such, but I do want it to sound like the one you have. Would the 40 series be louder than the 70 series?

Shaefers (a muffler shop here in town) said they would install a 40 series, throw in the 2.5" chrome tips all for 265 installed. Good price? Should I go for 40 series or is that just too loud for you all. All of your feedbacks are important to me.

It depends on how much sound you like. I am old, I can
barely tolerate the sound of the 70. A 70 on a Titan is
much louder than on most other trucks.

Like TITAN57 said...the 70 is louder on the Titan than other vehicles. For comparison, Flowmaster uses a 50 series muff for this same American Thunder kit for the Ram Hemi to achieve about the same sound level as the 70 on a Titan. A 40 series muff on my Titan would cause me to contemplate suicide! But for some...it may be just what they're looking for.

That sounds like a reasonable price for the muff swap and tips, but keep in mind that it doesn't include replacing the restrictive factory y-pipe, and you won't get any mandrel-bent piping...all of which you'd get with the Flowmaster kit for $417/shipped. You can install this kit in about 2-3 hrs yourself.

The nice thing about installing a good quality cat-back system is this: If you decide after a while that the muff is not what you're looking for, or you just want a different sound, it's pretty inexpensive to swap just the muff with another one. This is what I did recently....swapped the 70 out with a Borla XS. You end up with a hybrid...but you get the best of each that way.

As said earlier here, the 40 will be louder in the cab than the 70. As time and miles have gone by, this system has stayed deep toned with little volume changes for me, although some have reported their's had become louder. My favorite part of my commute is when I am going home up a 50 mph hill with sound barrier walls on both sides of the road for about 1/2-mile. The echo off the walls as I am cruising up it at about 2500 RPMs is a sweet sound.

quote]IM new to this.....so why do I need to replace the factory y-pipe? and why do I need madrel bent piping? Any info is appreciated. I just want my truck sounding sweet.

Someone posted a picture of the stock y-pipe and it was pretty restricted. An aftermarket one will flow much better. Mandrel bent tubing allows the pipe to retain the same diameter when it's bent. Otherwise the tube would crimp making it smaller and causing more restriction. Am I making sense?

That was my pic.....here it is again.

I was told and the muffler shop that if I changed or messed with the y-pipe, it would void my warranty, so they advised me not to mess with it, or atleast they wont touch it there. Liability issue for them I guess......

Also, they dont sell 70 series there, just 40. If I keep all pipes them same, not change with Y-pipe and have the 40 series installed, I wonder if it would have that deep throaty sound.

I guess smaller diameter piping causes a different tone on the exhaust, a not so pleasant one?

I would go to another shop....they don't know what they're talking about. You cannot void your warranty as long as you don't mess with the cats, and even then it's questionable. A y-pipe has nothing to do with emissions.....you can replace everything from the rear cats (4X4) or resonators (4X2) without any hassles from Nissan. Hek, most of the dealerships sell and install the Banks exhaust for our trucks which indeed replaces everything from behind the cats-back. You can buy a nice y-pipe online from Summit Racing and have the shop install it, or have the shop custom fab one for you...this is what I did with my first system I had.

As far as the 40 series muff goes, it will definately have PLENTY of rumble....too much drone for most that have installed one. Even the 70 has some drone, but the 40 is much worse.

****, I just read in another thread that a member advised that its not good to only install a flowmaster.....he said you should install a new catback system also.....how much does that cost ???

Will it really make a difference if I dont do that and just install the flowmaster? I'm on a budget right now, just got married and stuff, so if I have to, I'll wait to get the cat back system (which I dont know what that is or what its used for, all I know is TITAN KICKS ***).

Also, what is this "Drone" noise that you guys talk about? What does it sound like...

Also, what is this "Drone" noise that you guys talk about? What does it sound like...

If it were me, I'd save the $417 (shipped) for the Flowmaster cat-back kit. The Gibson has less drone than the Flowmaster and costs a little more...but is too quiet for some.

The best description I've heard yet for the drone is this: Imagine a squadron of B-52 bombers flying overhead....that's drone. It only happens between about 1500-1900 rpm. Basically, you'll hear the nice rumble of your pipes when you're on either side of this range, but inside this range you'll just hear the dull resonating drone. Even the stock system has a mild drone in this range, so listen for it next time you drive your truck and then just imagine that sound being amplified to get some idea.

Here's my Thread on the Gibson. http://www.clubtitan.org/postlite4408-gibson.html+catback
Either I've gotten used to it or it has "Settled", cuz it doesn't seem as "Dron-ey" as it was when I first got it.
I still like to "open-er-up"!!!

Somehow I missed your sound clips the first go-around, Tat. Your truck sounds mean, man (but in a refined kinda way...it is an LE, afterall!) :lol:

Hey my Titan Brothers, I just got a big block Magnaflow installed on my truck. The guy are the shop said everyone down here is getting then installed on thier Titans instead of the Flowmaster, Said those were made more for Mustangs (40 series) I took his advice and I love it. Single in, Dual out. 3 inch Stainless steel double plated tips. They have some kind of filter or something that keeps it from popping when I rev up the truck.....

The truck has a nice low deep growl to it. I love it, Its not too loud in the cab.....At idle its quite, like I wanted, and sounds mean when I punch it. at about 65 miles an our, its not too loud, maybe a little bit louder than it was at stock.....He told me I should expect about a 13-14 horsepower gain. I didnt change the y pipe. Maybe when I have a little bit more cash to shell out, Ill do that.

Should I change the resenator? What does that do?
And the cats, if I change that, will if void any warranty on my truck?

...Should I change the resenator? What does that do?
And the cats, if I change that, will if void any warranty on my truck?Don't mess with the cats as it is illegal to do so in most states - you'd have a hard time getting a shop to do anything with them anyway as they don't want the liability for screwing around with your vehicle emissions. The resonators located just aft of the cats are mainly there to quiet the stock exhaust volume. Some have replaced them with straight pipes and some have replaced them with less restrictive resonators or bullets.

So then I dont need the resenator? I wonder if that would mess up the sound that I have now with the Magnaflow that I put on yesterday.

Do they usually wear out after a while (the aftermarket muffler)? About how long will they last sounding sweet?

DAMN I LOVE MY TITAN.

DAMN I LOVE MY TITAN.I think some have reported their exhaust note becoming a bit "raspy" sounding at high RPMs when they went with straight pipes, but they did gain some performance. Muffler endurance will depend on weather conditions and material (stainless steel, aluminum, aluminized-steel). I would expect they last as long or longer than stock mufflers. Some aftermarket exhausts will have a slight change in tone after a break-in over a few months.

This is my Titan with a single in, dual out Magnaflow and Double Rolled Tips....I have a sound clip, but I dont know how to put it up.

Well, I dont know how to stream up, But I uploaded my video clip with sound of my exhuast, Please tell me what you all think....

What is it? sounds good, not loud at all.

Its a Magnaflow, the "big body" style as the guy at the Muffler shop said. 3 inch double rolled stainless steel tips...It is suppoed to help prevent any back popping when you punch on the gas.....Ill try to record a better sound clip when I have a chance.

Looks and sounds great....love those tips!

Thanks Rocky, It means alot to me hearing it from someone like you or Calititan.....I have the factory Y on it still.....I dont know if gettting one fabricated will make it sound a lot louder, deeper or what....If anyone thinks its gonna sound louder, let me know. I'm not going for that...I want a "deeper" "throatier" sound.

That sounds awsome. This is excatly what I am looking for. I was alittle unsure at first, but after hearing it I have to have one.
