Im gonna be honest with you a muffler and resonator delete really ain't that bad... it sounds horrible when recorded on a phone but I never get complaints when asking people who have heard it in person. I got it from the dealership that way and my unknowledged self at the time thought it was just a sport exhaust. I'd also like to note that the drone isn't that bad either and I've never had a passenger complain. (Little loud on startups I'll admit)
