yes the motor is awesome...and yes I like the bigboy pipe for sure....
ran at a proseries race this weekend and the motor was awesome, tunes easy and was one of if not the fastest thing there running it around 230 range.. qualifyed 5th in pro made my way up to second then got completely violated in a 180 turn and had to come off the track to get fixed then came back and got 6th only due to being I think the only guy who could go 10 minutes so I eliminated a pitstop to make up ground...this B5 is awesome, and although it doesnt sound like a 2013 it still sounds awesome with the bigboy!!!!
but as someone mentioned yes it does seem to like the bottom a hair fat
I believe I am 1 turn out from flush but thats just my settings for where I was
