enough boost is when you have 3 dimple marks in the hood from the valve cover nuts..
On my supercharged 1.6 I had 2.5 in no cat, no muffler stack that comes out right behind the driver side of the bed.....gave me horrible head aches. I have a long swirl pack muffler on there now, it sounds better and doesnt leave me reaching for Advil
does anyone have an exhaust that dumps right after the downpipe?ie: no exhaust past the engine bay?does piping it all the way back make a difference in the sound?or in power?
