okay heres the deal im running 17 PSI and all my turbo piping keeps blowing off or blowing up. the 3000 coupling blew apart and the other pipes have all blown off no matter how hard I tighten them after I get on it for a few minutes POOF! So I got fed up wento the supply house, got a 10 foot long pvc pipe and various elbows and made my system all hard piped right from the bottom rubber turbo hose downpipe. Okay I know what your all saying, your stupid it will never hold the boost... yea PVC pipe is rated up to 180 PSI!!!!! very easy to connect, light and cheap. AFTER EXTENSIVE TESTING WORKS AWESOME!! -- Eric
