My only thing with test pipes is Ive heard more problems you might incur because there is no restriction. High flow cat you still have a small cat in their and wont have to worry about being illegal. On the other hand you should give Blake from 3zero3motorsports an email and see what he can work out for a deal for you.. He treats his customers really well, deff doesnt hurt you to give him a shoot and tell him "Jed" told you to get ahold of him". Blake@3zero3motorsports.com. Keep me posted!!
