I put an aluminum oval slip on Hindle on my 03 636 and I am thinking of going to the Two Bros C2 Oval aluminum instead. I am after that deep, throaty sound as compared to the shreak of the Hindle. I love the Hindle looks but sound wise it isn't quite what I was looking for. I guess I can sell the Hindle and go for the Two Bros. Opinions from Two Bros owners?
