Cool Thanks TAZ:

Hey my buddy does exhaust also and he said he can do it but was wondering what size the exhaust pipe is going into and coming out the the muffler, is it like 3 inch or what? He also was wondering how long that stock muffler is, looks like at least 2 feet long.

You are about right on stock muffler size.
We did 3" if I remember right to the mufflers and then down to 2.5" going out so We had room for 2 tailpipes over axle in stock tailpipe location. The reduction in size was also to mantain better back pressure as We were alittle concerned about flowing to much exhaust and hurting performance since I had headers and the dual chamber muffler. Just felt like beng a little cautious with back pressure. Maybe worried for no reason on that issue but the sound is sweet.

I have cherry bombs now into dual exit. What do you think would be louder along with good performance.?
