my thoughts, why not a van or truck cat, would they be less restrictive?
elimiate the baffle thing, or what ever it is between the cat and muffler.
then one of those muffler that have two exhaust pipe, only 2in. opening or so, so is not to wake up the whole neignborhood when going down the road? Oh, 89 turbo family wagon, oh yeah, I did that little thing with the fish tank air control valve in line on the waste gate vaccumm line, I did notice the turbo working what seems to be quicker, sooner and harder.
now where is the screw to maybe turn up the boost some, but ofcourse back to the cheap way of opening up the exhaust, to me it feel like no matter how much I turn up the boost, I still need a cheap way to exhaust it.
