I did the delete on mine back in Sept and it sounded great at first. After a couple months it got to be too annoying at highway speeds....the droning was awful and when I crank the stereo I'd lose the bass from the music because it was muddled up with the exhaust.....I slapped a flowmaster fx on it, which made it a tiny bit quieter.....but not much....and it still drones. I wish I had just gone with the cat back originally.....but oh well. It sounds great on a cold start and while accelerating, it's just at highway speeds I don't care for it. When it starts to bother me too much I just stomp on the pedal and then it sounds great again
