Default LT header gains with H/C setup

Hey all my H/C is in sig, just wanted to know approximatly what sort of an increase Ill have from LT's(pacesetters) and a ypipe with high flow cats. Im hoping for about 25rwhp. Currently Im running edelbrock shorties and stock cats.

I dont see why you wouldnt hit 420rwhp, especially if Ryne does a bit of tuning aftre the install.

Is yours going in monday? Mine is on the board to go in Wednesday...its gonna be a long week!

****, you would gain 10-15 at the wheels on a stock motor. Calculate that percentage on a motor making 50-60 more at the wheels than stock. Id say a good 20rwhp is achievable, especially with some good high flow cats....that is, if you have to run cats.

LTs + Tune on that setup IMO should net you at least 415-420rwhp, even through cats.
