Well Since I got my GT Last year I ran it once stock and This year I put a K&N in and an OR X Pipe from UPR and a Magnapack Catback system. Here is the results interesting to see the difference in time and ET, but by no mean fast yet, But I have an Auto and a Convertable, so 2 strikes against me already.
