Alright guys, well my exhuast is all set, but have one problem now. Not sure it is exhuast though. When i first start the car and I put my hand down where them clamp goes to the manifold. I feel a breeze ONLY when i revv it up. I have a hoel in my air pump muffler, could that be what i am feeling? That is right there also. Any help would be good, thanks
