Well I know that the straight pipes definentally help in the high rpms, but it acts like it's got a turbo on it lol, it don't really get up and go till about 2500 rpms. So I think that I might do those MAC dumps; they're cheap, I've got MAC headers and o/r h-pipe so it'll probably fit better than other brands, and it'll still be (somewhat) loud. Just one more question, when you are sitting there idling, you don't have any problems with exhaust fumes coming into your car do you, from underneath?

tailpipes will help with the back pressure and it will sound a lot better, not just loud

Ok well I've had flows before too, and they do not sound the same. The mac is a little deeper, and i gained more power when i switched to mac. and ive had flowmasters dumped, and when i put the tailpipes on, i lost power from too much backpressure. But either way go with a 2.5" setup.

is sound a factor? i always heard Mac was better performance, but flowmasters was more for sound.. i personaly have flowmasters on my car. and i love it.

flowmaster for sound
mac for sound and performance


tail pipes are for show cars.

I have flowmasters on my 5.0 now, can I still use those if I decide to go with MAC cat back system? Also, do you guys recommend leaving the cat converter on the car with thise set up?
