Might have found the problem…
So the other day i posted a vid of saying i want the whining noise of my gsxr 600 back. And I also noticed that its got an ugly noice when i accelerate which sounds more aggressive. so i checked my exhaust system and it might have loosened when i crashed. this is how it looks. and also since the exhaust is louder maybe all the other noises get cancelled and thats why i couldnt hear the whine.
