Re: y pipe?

How much boost are you running. Bottom line, you should pressure test. You should be able to hold 20-30psi no problem. Any piping that isn't holding that much needs a t-bolt clamp, any vacuum hoses that aren't holding are probably old and dry rotting and need to be replaced. At stock boost pressure there is no reason anything should be popping off or loose...end of story. Regular idle should be 700rpms. Seriously, pressure test and replaced old hoses and tighten down piping. With a new rubber gasket and t-bolts on a metal y-pipe with rolled lips, I've never heard of one popping off at anywhere near stock boost levels.

Your 1996 Mitsubishi 3000GT VR-4 is the 92nd out of the 315 that were made that year. Only 21 of which are exactly identical.
