I got my exhaust for 400 with custom tips and a 3" pipe from the cat back with a res delete. It was fairly reasonable. I wish I had the bora exhaust with a 3" DP and no cat but we cant all get what we want.................... for now! I am saving up and modding my car to hell lol.

When my exhaust was leaking badly the car was definitely sluggish, loud, and dangerous in stand-still traffic (I think I lost some brain function) but the engine still ran fine. Prices for the exhaust job in my area of CT were so high (even the "custom" shops) that I ordered the Dynomax catback system and I couldn't be happier. I saved $$$ and the car sounds and responds great now! Find a reliable & cheap custom shop or spend the money on an aftermarket exhaust. I did and now I've got the modding bug.

3" on a GTP with no res or muffs sounds sick as heck.

Every GP I see at the track (rare) they are running 3" straight pipe and usually cat-less.

Very loud and throaty. ALMOST V8 like. ALMOST!

Personally, if 2.5" can be gotten for under $200, I'd go for it. I payed $250 for my 2.5" cat-back with no rez. I even had them leave the muffler on with clamps so I can take it off for the strip.

I'm considering taking it off tomorrow and just putting some spare 2.5" pipe on the end. I'm curious to see how it sounds. wink

There is a guy I know at GLD running 3" straight pipe. I've seen/heard that set-up first hand.

He didn't even have a 3.4" pulley on it yet either, totally stock although I'm not sure about his manifolds, those may have been PEMs.

Did you replace the cat, or did cleaning the MAF solve your drivability problem?

If you cleaned the maf once before, I'd just go and get a new one and be done with it....

don't buy new... too expensive, get a used one from Ed Morad, he sells them for like $45, and i believe he gives a 3 or 4 month warranty on them
