headers 440 dart

Whatever you buy, make sure they are ceramic coated.

Pro-parts can be installed with everything bloted in place. The collectors are a ***** to get on, worse to service.

The TTI's are a MF.

The schumachers fit really well but are very limited on flow. 450hp is the max for these. Even in their own testing the comparason from TTI's to Schumachers is staggering. Theer are some guys here who have also switched and see major power gains.
