Purchased the Firefly side pipes a couple of years ago. Very pleased with the both the quality & service. From my seat, very good value.
Upgraded my engine last year & moved to the Firefly headers. Once again, very well pleased with both the quality & service.
To my taste, they are both a big step up in appearance.
Performance gains? I'm not sure but I do know I have a lot more performance now. <G>
