after hearing the sound clip of the gibson exhaust and borla turbo muffler what would it be like if the exhaust was stock with the borla muffler? Same sound?
My truck is fast enough [well at least for an old man] but I sure would like that sound

If this helps any, I pretty much have the stock exhaust in place from the manifolds back to my Flowmaster 40-series, and from there I had a custom single tailpipe and tip bent and installed. I didn't like the stock tailpipe. I'm not familiar with how the Borla sounds, but the 40-series is Flowmasters' loudest muffler, and I don't get too much "drone" in the cab. I prefer being able to hear what my powerplant is doing, so I don't mind the sound. Anyway, I have the factory Y-pipe and the resonators are still in place. My truck pulls hard when accelerating aggressively, and with the 77-series intake, I haven't experienced any noticeable loss of low end grunt or top end acceleration. Bottom line: Decide what you want and then go do it. As long as you are happy with the results, that's all that matters. As for being an old man, hey, we enjoy turning heads on the road as much as the youngsters do!
