Curious how this setup performs. I wan't to keep my cats + quiet ARH catback that I already have, yet I want more power. Already have Lund Tune + Steeda intake + ARH catback.

There are a few on here who are. It will still gain power even without headers and no cats.

I'm running the GT350IM and stock headers. If you care about dyno numbers I put down 426rwhp with an auto. Lund tune, Roush CAI, solo street race catback.

Stock intake, hpipe, 3.31 car, stock TB, GT-350 manifold. Car runs strong. My bud has a PP car, JLT intake, headers, no cats and the gt350 manifold GT-350 t.b. He trapped .5mph faster same night.

I have the GT350 IM and stock exhaust manifolds. I plan to do LTs in the future. The IM works wonders. You can do it separate from LTs or do LTs first or do both at the same time or just do one and not the other. Either way you'll gain a significant amount of power.

One just needs to know that oem manifolds are like shorty headers. They are not like the cast iron blocks that were awful for flow of just a few years ago.

Yup E85, density altitude was over 2000ft, 12psi Hoosiers. The 12.03 is me btw, car needs shocks and springs ... The base GT suspension can't handle the launch. Finishing the 1/4 mile in 3rd gear lol

None the less still impressive. Get a GT 350 CAI and TB on there, might get you into 11s.

Lund tuned or custom?

Lund FF. More is to be gained with shocks and springs then with an intake. Will do headers before a "cai". Better driving or better air would have put me sub 12s, but no excuses.
