I been changing out exhausts and tried two different round mufflers, a 14inch long magnaflow and a 20inch long vibrant, the round ones seem to not sound so good, what size oval muffler can you fit under thur?

go straight pipe

Yea right, I have 3inch downpipe + full 3 inch exhaust + 12" vibrant exhaust resonator + 20" long vibrant exhaust round muffler and it's way too damn loud, I'm moving down to 2.5" and trying to find something that won't drone and sound like ***. It's like driving around with a sine wave coming from a 12inch subwoofer turned on right now.

Or if somebody wants to link me the quietest 2.5 inlet magnaflow muffler that will fit a 180TT off their website that would be swell: http://www.magnaflow.com/02product/s...ain&id=301

I'm looking at the greddy exhaust for TT in this picture and the tip is 101mm (3.98inches), so judging from the tip size, that muffler looks like it's about 12 inches long, when I had stock exhaust on and measuered it was 20 inches long but I don't remember if it was oval or round.
