I run a 2.5" with a turbo muffler, it's very quiet.

 

My DelSlow started it's boost life w/2.5" piping, 2X resonator & fake muffler (Just a big 5" pipe). It was too loud for me. Added a cheap ($65 Ebay) flow through muffler & it purrs once again.

 

Check out Dynomax exhaust systems for you car! they make pretty good systems and arent that expensive.

I would call them and ask about the flange sizes, because my exhaust was nice, but it had a stock size flange, so it could fit up. But for your car they have a full catback i think. check it out. My exhaust is really quiet!!!!

 

I'm running a greddy full catback sp exhaust, I like the queit sound so it works for me, I heard that thermal reserch&development makes a 3" cat back designed for turbo at about $600.00

 

im running a full 3 inch dp and 3inch mandrel bends with no cat muffler or resonator until the second bend in the exhaust and boom stiragiht through the sidskirt out the car lol sound great but loud lol

 

Well on one of my volvos, I have a bored out factory exhaust manifold, 3 inch complete exhaust, no cat, a resonator inline, no muffler and a small 3inch brospeed tip for that chrome look. Loud as ----.. I've gotten so many people to step up to me with it, I of course have to step down if it's a v8

 

I just looked into dynomax, they had flow specs and all sorts of ---- on their website. The welded one, straight flow design looks decent.. better flow then the Stainless and cheaper.

I was bored yesterday and I went to all the big sites, flowmaster, magnaflow and such. The magnaflow website sucked, picture of that homo owner was ------- everywhere, yeah just what I want to see instead of detailed specs. I really wasn't impressed with their designs. Flowmaster is flowmaster, nothing changed, I have one new hanging out in a closet some place, I'm sure one of the cars will find a use for it.

Next time I need some mufflers, I'm going for that high flowing low noise dynomax one. If anyone else has first hand experience, please share.
