header only 2010 makes 407 rwhp / 403rwtq!!! we installed an off-raod Dynatech Supermaxx header system and a bone stock 2010, dyno tuned it, and made these numbers!
this is through stock mufflers, the sound is fantastic.

sorry Bryan posted it was offroads, but it was a catted setup
We did not do a baseline, but we have ran many stock and seen nothing over 376 on a 6 speed. This car still has the stock air intake and catback..Supermaxx setup still retains the stock mids and resonators.
The sound is killer through the stock mufflers and when he returns next week I will try to get a video or I can take a video of our shop cars with the same exhaust setup.
The fit was great!
