I've been getting confusing advice as to whether the Header and HFCs will be good or bad for the SC kit. 
Have heard Stillen strongly recommending against the headers (loss of psi and lean A/F), as well as, headers working well with the kit. And HFCs not being able to take the extra heat.
I am seeing some member here running header+HFC with the SC kit.
Any advice? |
My advice is keep stock headers and cats. I had HFC's and one cat blew after a few hundred miles. When I went back to stock cats per Stillen, I made more power also. A few other's I know personally also lost power when going from stock cats to ART pipes and went back again to stock cats to get the numbers back.
