--------------------------------------------------------------------------------
JBA Evol production change sucks!
Good Morning Everyone, I just received my JBA Cat Back sytem part # 50-1400. JBA changed there product design and sytem now sucks.
I picked JBA because they change out the resonators with the Cat Back system. So you get the additional benefit of picking up 8+ HP by having them removed plus another 9+HP for unrestricting the exhaust. (17HP and 23ft lbs of trq!) JBA no longer replaces the resonators with there Cat Back kits for Titans since the lovely state of CA decided it is a mod to the emissions. $350 for 9HP and 12ft lbs trq is not a good deal but a RIP OFF!!!
I spoke to AC at JBA and he apologized for the mix up (product change!). Another interesting point to make. I received no instructions and the muffler was not a JBA but a K&N! I inquired about this and was informed JBA purchased K&N exhaust devision and is including K&N as a subsitute in there kits. I purchased a JBA not a K&N.
I look forward to hearing from everyone! Pissed OFF and let down! :twisted:

They told me the same thing about the K&N muffler. I guess I got lucky and mine just in time before the production change. I would return in a hurry. I actually replaced the muffler with a 5"x11" magnaflow because of the K&N's cab drone and excessive resonance. The Magnaflow and JBA pipes seems to work out just fine.
My wife told me to go ahead and install it, I may like it. I used there published article from Trucking magazine as instructions and completed the install. The mounting holes on the flanges need to be 1/8" closer together; I had to tap them on with a hammer because the clearances were so tight. (JBA needs to readjust there jig!)
The resonance drone is terrible with the K&N muffler especially from 1400 - 2300 RPM. I examined the inside of the K&N before installing it and noticed there sound absorption material looks likes fiberglass.
The fact that JBA changed there product and did not update there website and dyno results is a misrepresentation a.k.a. fraud to the consumer! OK let me purchase a genuine diamond ring on line and get sent a cubic zircon! :evil: :twisted:
I am going to give JBA one opportunity to correct this and redeem the quality of their product and reputation! I will keep everyone updated!
I spoke to AC yesterday 03/28/05 and he is trying to get these issues resolved. I will be calling JBA this afternoon for a followup! I should be given a set of pipes with resonators and a JBA muffler! One that does not have a loud resonance drone that is unbearable. I will keep everyone informed of the outcome.
Thank You, for your support! :)
