RE: RS4.18 cvr Exhaust????
I don't think over tightening is the case i could only go so tight with a screwdriver lol but i noticed both headers sat very close to my pull start (the thickness of a piece of paper) so maybe the vibration through the engine was putting pressure on it and at high temps the aluminum became weak and cracked. I was thinking of the vantage pipe but i have heard a hot muffler is better then a cold one and the carbon fiber doesn't heat up?????? The ths pipe is nice very similar to my rd logics pipe but its allot cheaper which is nice!!
