The left and right mufflers on the 08 I have were totally different on the inside, the right muffler basicly had a set of tubes in there that overlapped each other at the middle and were flattened almost in half with the openings on aposeing sides. The left muffler just had a baffle in it at the exit with the inner end crimped closed. If you go to the americancustom.com website and look at there baffle selections you'll see long ones and short ones,the long ones were in the right pipe the short ones were in the left pipe. :newsmile082:whew that was a mouthful.
