I'm a flowmaster fan and I've been running them since 1992 on my mustangs. I'm now seening a lot of people running the KR pipes on their 4.6L Stangs. Looking for some inputs on what your running on your Shelby GTs. By the way has anyone been told this voids your warrenty? Thanks
Hi there, I got a GT500 and I put on a set of the KR mufflers as the stock ones were to quiet. No problem with warranty as I got the dealership to install them prior to me picking up the car.
