Fitment was flawless, nothing but compliments on the sound even though the stock exhaust is rather restricting. I unplugged the exhaust valve while doing this install too so that both tips are always open (you must unplug after the valve is already open). Will post sound clips soon
did you purchase the "sport" or "race" cat back?
