Wnt2gofst can prolly tell you all about it.. It won't be much help if any unless your willing to bump the rpms to at least 7500.. From what I've seen low end torque loss and hp gains from 5800-6000 and up.. Some places sell a tune w the manifold if you have a tuner already..

As our pm it is going to hurt you with rpms you plan on spinning and in the 1/8. A better mod would be gears.

He's prolly got dyno graphs to show you.. That is also with a tune though.. Can't do one w/o a tune and run properly..

That is right on the 5.0. I made 414whp with tune and cold air. Added off road x pipe and only change was shut off o2 sensors. Car made 432whp. Same day both with hour cool down.

Its been proven the worst part of these exhaust on the 5.0 is the catted x pipe. Deleting the cats are huge on these cars since the headers flow so well.
