Hi Guys.. anyone ever used Hindle Stainless exhaust parts? seen a nice replacement 4-into-1 online for the RR6 and thought I would sue out of anyone has used them / opinion on them before I buy it. Bike heavily modded.. already got a Remus Can, Powercommander and had it on the Rolling Road for a custom map - 155bhp at the wheel. I'm sure the power would (at best) be a couple of HP more, but the sound should be a lot better as well.. any comments?
