I run the A852, A872, and the 2081 pipe. Everything fits really nice in there with the exception of the manifold. It can be tucked inside the stone guard, but it will rub there and on the body. I did not like this so i went to the Nova 41030 and 41029 manifolds. I was also afraid of taking a hit on that side of the car and it breaking something. I know it can still happen but there is just a bit more play room there now.
