take it to the dealer bro, honestly, you are spending as much money having 4-5 dudes tell you otherwise, i duno about you guys, but the acura dealership here in tucson is great, great service, price is expected, rarely have to wait for an appointment, overall worth it, they work on acura all day, so why not, just a suggestion, its what i ended up doing over all, warranty or not, and how slammed in your gsr? scraping bottom over speed bumps cannot be that fun haha, my friend has a civic that omg haha so slammed, tore the muffler off, what a dummy he was.
