The PPE ISF Headers make a significant increase in flow compared to the stock manifolds. Tube lengths and diameters are increased coming together into a ported 4-1 parallel merge collector. Completely TIG welded construction with thick 16 gauge tubing for long lasting power gains.
Optional high-flow stainless steel ECT cats are an option. They get welded into your stock or aftermarket midpipe.
The headers with no cats show a 38-46whp gain
The headers with high-flow cats show a 28-33whp gain
Our new design does not need to relocate the dipstick tube, it fits with the stock dipstick tube.
Our headers come with Evolution Performance Ceramic Coatings that add good looks along with thermal barrior properties that increase power and lower engine bay temps. They are also a great protection against corrosion.
The finish will stay looking great longer than a stainless steel header and perform better.
