if you have a non SI with the R18A1 and you have an exhaust i'd like to see if anyone would like to sell me or give away the stock part of the axel back. i just got a HKS t1 carbon fiber muffler for 100 bucks and i dont feel like going to a muffler shop to get the piping if i can get it from someone here. if i measured correctly i think the axel back part its roughly 2.0" IF i measured it right. so if anyone can help me out thatd be sweet

You could go to a car parts store and buy a pipe cutter and some clamps and do it yourself.

 

yea i never even thought of that thanks for the input.
