Video of Flowmaster 40s on my 461ci
I've bounced back and forth on a few different muffler and I thought I would post this video in case it is of help to anyone in choosing.
Headers, dual 2.5" with H-pipe, and Flowmaster 40 series that are right before the rear axle with outlets facing down. https://www.youtube.com/watch?v=RlHVKA6_KKI |

Sounds similar to mine when I got it. Headers, 2.5" exhaust with X-pipe, 40-series mufflers, then out to the bumper.
