I retained all the stock piping, but basically swapped out stock muffler for a Flowmaster 50 SUV muffler. 2.25" in dual, 3" out single.
I don't know if It's in my head, but it feels like I lost power.. butt dyno throwing me off here.
Would a power loss make sense here of does my butt dyno require calibration.
