Was a direct fit. But needed to move muffler closer . no more code for my car and that's all I wanted .

My first upgrade was a 18" magnaflow universal muffler. Good for tooling around town, but the drone at highway speed was giving me migraines. The gibson is a very quiet exhaust by comparison. You can barely hear it in the cab, which is nice. If you are behind the car, it gives a nice mellow rumble. Performance boost is subtle but noticible. No fuel economy benifit over stock. The appearance is excellent, although I may get bigger tips in the future.
