I called about there pipe and why they are only doing a slip on for the RR. I was told that you really can't improve on the factory's work is what I was told. :roll: But they have the dyno chart up and all it seems to do well with the stock inj. gained 4hp up top nice gains in the mid range too. Still not sold on any exhaust yet.
