or you could do what i did and have a custom exhaust made.
all stainless everything, modified tt hi-flo cat and downpipe to straightpipe to bosal muffler
all 60mm tubing, ran just over $1000 with all the work
sounded AMAZING, at first lost a little lowend but the cams more than made up for that. if i were to do it again, i would just have bought maybe an acs or bb tri-flo system. much easier to install and sell afterwards. no one likes high quality custom work anymore
