Bro shut the f*(k up and go drive a turbo car, and then come back and say "hey man these turbo whistlers are cool!!" i bet you won't come back to this thread after driving a turbo car. And for the record they look like a piece of shit clamped onto an exhaust tip, they also don't sound that great, you might as well pay one of your mates to hang out the window and make a whistling sound and then sneeze when you change gears coz that to me seems a lot less wanky
and who said it had to be a loud exhaust? iv got a full aftermarket exhaust and its within the set DB limit, and it sounds nice, not loud. AND my rims are aftermarket as well but there still 17", again they just look better than factory. The turbo whistler is not even a turbo whistle, it sounds nothing like it so you can stop trying to compare that to every other vehicle modification that you think is wanky, coz the whistler doesn't improve ANYTHING
