I've got a set of Erion dual slip-ons with all the required hardware. They have polished S/S midpipes, Carbon fiber cans, and titanium end caps. I've put approximately 4k miles on them while on my 07, they're in good shape. The pipes were used with a Power Commander 3, a Jeffo map, and made 177 hp. on a Superflow dyno. The map is free with the purchase of the pipes. They have a little deeper rumble then the Oval Muzzy's. They sound reasonably quiet at idle, they start to bark real nice around 7k rpm. Going down the highway, at 4-5k, they don't require ear plugs. They will fit 14's from 06 thru 11 with the proper pipe gasket. I'm asking $275, thanks for looking.
