The muffler fit as expected to all of the measurements listed. Great sounding muffler when you have to tone it down a little over a straight pipe.

Easy install, just cut existing pipe and install, using exhaust clamps. You'll need to order the clamps or pick them up. My truck was straight piped for some time, it was at least a 20% reduction in noise at idle and maybe 50% noise reduction when high reving to upshift.
