> [@88slowmarro](#): > > on a v6 it will sound like someone fartin on a snare drum …but if ya really want them out pull the cat dont gut them it will hurt performance rather than help as it will cause rolling turbulince in the exhaust and not scavenge right pull the cats off and weld in new pipe or get a off road pipe at least do it halfway right not halfassed and lazy…as far as n.y.s.i goes its all in who ya know ;D A lot of things shape the exhaust and a turbo car isn’t losing anything from guttin the cars. ---

Well my car is NA, so no turbos to muffle the exhaust. > [@Shawn96VR-4](#): > > It will vary car by car. Without the catback it was one of the loudest I have heard for an import. I assume you’re talking about your VR-4? I wouldn’t have any qualms about gutting the Z if it was TT, but I’m not sure about back pressure on an NA. I’ve heard people say that its necessary for higher low end power and I’ve read some articles arguing that it doesn’t even exist.lol ---

I’ll just apologize and say I thought you were TT. 🙂 ---

its not backpressure that helps performance its scavenging thats why diff lenght headers will move the power band around on cars long tubes mid to top shortys low and mid then the rest of exhaust its a complicated formula :nod ya need to see what ya want and go from there ---

If you lose power you’ll be more likely to go turbo :lol :nod ---

> [@NedZ32](#): > > You use exhaust cutouts? Vband catalytic converter. edit… some cars sound downright nasty(in a good way) with open downpipes, B5 S4’s are one of those. turbo’ed VR6’s and i think my 1.8t sounds pretty nasty open downpipe since i have the big turbo on it… ive heard a stealth TT on open downpipes with 16g’s and it was a good sound, so Auggie, even you get the boot since its the same car. ---

Test pipes are pretty cheap. Buy them used for ~$30 each. Sell your cats and you just made money. ---
