I've heard alot of you guys talk about the great performacne gains from a full exhaust system such as Y Pipe hi flow cat, and custom B Pipe. My question is just how loud are they? I am looking for something that would be no louder than stock, and if that is not possible, I want the difference in loudness/sound to be civil and more atuned to a luxury car as opposed to angry bumble bees in a tin can. Who offers one that would meet my criteria? Also, my OEM muffler is still in perfect shape, so could I keep it with a hi power exhaust system to keep the sound down?

 

Well, I just got through talking to Dallas at Warp Speed Performance, and he pretty much answered the same questions for me. It might help to give him a call.

But based upon the information he told me, the sound may be slightly more than stock on acceleration, but not much. And definitely NOT like the 'bee-in-a-can' sound we've often heard from.... dare I say this.... riceboy cars!

And that's MY $0.02 worth!

 

I'll try to give him a call in the coming week. I've heard pretty positive feedback on the forum about WSP so I may end up using them. What about using my OEM muffler? Will it work?

 

As far as the high perf. cat. You might want to check out the post about this,I belive its called "just purchased a high perf. cat" we just finished talking about it.
