So for a few weeks ive been pulling up my driveway and have been slightly scraping it. Im done parking up there. However, my question is, should i look into a new exhaust set up? i dont mind spending some money, and i certainly wouldnt mind some performance gains and a deeper tone. I think my exhaust sound is pretty nice as is but deeper would be better. Any thoughts? could i have done any damage pulling up the driveway? Suggestions on new set up?
