Hey guys, I recently had muffler delete and the stock tips welded back on. No other video on youtube has this howling sound when they accelerate away. The noise overpowers the exhaust note and can be heard echoing really loudly. Could this be caused from the stock tips? Skip to 0:37


Thanks!

lol it sounds like its whistling now. As in something in the area where it was modified is causing this in the piping.
