I can check when I get back from Lime Rock this weekend but I should have some used pieces, and if not, I can get new ones.

Hi James, What difference do you get from your headers on an '011 Cup? Do they still run cats?

James-GMG

I originally ran the PMNA RSR header and muffler system but when it got damaged, the replacement cost was incredibly high, so we built our own headers and in fact, we gained more torque that the PMNA setup and only lost 1-2 hp.

Overall we gained approx 18 hp and 15 torque at the wheels.

Our system costs half the amount of the RSR setup.
It does not use cats.....it's loud too.

Still have the stock headers and muffler available.........

Bump with a 10% price reduction....
