I know there are a lot of exhaust threads but I'm planning on installing duals and after reading so many threads about exhausts I'm really more undecided than ever. For those who've already done it, I'd like to know why you chose the brand you did and if you went with a true dual H pipe or a y pipe? Either way, does changing the exhaust increase the HP any?
Also, did you purchase from the installer or online?
