Thanks for the replys, very helpful! Been talking with a local shop, gonna run 3” off the collectors, x pipe and into the mufflers. Sounds like a 20” body should give me the sound/tone I’m after. I’ve always like the sound of Dynomax so gonna use those, offset in center out. 2 1/2” tailpipe out of the muffler to a set of stock looking bright tips.
