I also had an AEM fuel rail and a FPR set at 5psi more then stock for the cams. And it was a CAI not SRI.
Qtiger, why would I have gained 10 hp with a different header?
Do you mean if I had a 4-1 header?
That 2 piece DC 4-2-1 is just trash imho. A longer primary header or quality 4-1 makes an enormous difference... and once you have aftermarket cams, it's an even larger power gain.
2.5" collector wouldn't hurt either.
