I need new exhaust and I was wondering what you guys have and what you think sounds the best.

ive got apexi muffler without silencer sounds great, not too raspy or loud annoying like civics, oh ya its v6, so it sounds good on it, Im thinking of bolting on test pipe instead of cat soon.

i have a custom-built powertech muffler. sounds REALLY nice, used to have a wav file but not anymre.

personally i liked the cheap one i got from autozone.. *shrug*

best sounding muffler for the 4 banger? and what size piping should i get....I MAY switch over to bpt later on but not sure.

For the 4-cyl, you want to keep the pipe narrower to keep gas velocities up, but if you ARE going turbo later, you'll want a bigger pipe to decrease back pressure. The real difference is that with the larger pipe you'll get a better top end & high RPM fuel economy, but the smaller pipe moves the power band down for a better low end tourqe.
2.25" was the largest the folks that built my system reccomended for a NA 4-cyl.

As to what sounds best, thats up to you man. Some people actualy LIKE the sound of those gawd awful irritating fart cans,... Sounds like a 400lb bumble bee to me. I prefer a mellow tone with an edge when you get in it, but something that wont attract the cops eyes every time you drive by.
Get a better idea what sound you want, then you can get beter answers.

That is exactly my sentiments man I am looking for something that is only loud when I want it to be, ya know? I wish there was some way we could get the roar of good ol American muscle lol but with a 4-banger not really possible to my knowledge.
