I wanted a bigger bore exhaust on my BJ8, but was too cheap to just go buy one, and I wanted headers too. So, I am running a set of stainless headers from AHSpares and I custom made my exhaust, which follows the original path. Dual pipes, 1 7/8" OD, with a Smithy's glasspack for each under the seat and two more out back in place of resonators. It provides a bit lower tone to it, but on par with stock for volume and really smooth. I love it. On the highway you can hear it slightly, but with no drone or other nastiness.
