Save the dawn for your dishes!!!
yes I know. They actually have tri-y mid length headers. That's besides the point. I would love to see proof of 20rwhp gain for an h-pipe alone. All test that I have seen they are getting and 38-40 with long tube headers and mid pipe with cats and about 5-7 more removing the cats.5 DOT 0 said:I'm sure you know this but our cars don't have exhaust manifolds they have shorty tube headers, the same ones on the 5.0's, 302S and 302R.boss2511 said:He doesnt want to run headers.....that is where the power is coming from. Stock manifolds removing the cats...with what I presume to be a off road h-pipe say it is a full 3" mid pipe than maybe its worth 10rwhp in itself. if just removing them and puting the 2.75" back in its place it isnt worth much.
