I replaced the stupid noisemaker pipe (the one that T's off into the cab) with a 2" to 1.5" pipe...cost me five dollars....yee yee. Ok it ran fine like this until i upgraded the recirc valve spring. Now if im really driving like an *** and I am under hard throttle as soon as I clutch to shift (hitting 12-13 PSI at this point) somehow the thing pops apart. I believe its as tight as I can get it without cutting the hose. Long story short...i know plenty have done this, what did you use to replace this?
