I put a Joe Z exhaust on my 2012 ISF, 36k miles and have put about 700 miles on the exhaust. I am interested in purchasing the PPE Power Package..Headers / Tuned intake and Tuner from RR racing. What kind of actual WHP can I expect with the Joe Z exhaust using 93 gas on a Dyno with the power package? The Joe Z exhaust already felt like a big difference once it "broken in" and I am sure the power package will really wake the ISF up. Any help is greatly appreciated! Thanks

First off exhaust systems don’t “break in” you just get accustomed to them. Same goes for “settling springs” it’s not a thing. RR racing has the dynoes on the website so it will be similar (if your engine is healthy) that’s why they list them in the pics with the package.

I see the dynos, I am asking specifically on what others are getting with a Joe Z exhaust system and that specific upgrade kit.

Hey,

The exhaust will be like any other exhaust. You should be at about 410 whp.

Contact us for pricing on the RR system!

Like Josh said the exhaust shouldn't really make much of a difference. I have the RR Racing performance package and a header back Hayward & Scott exhaust setup and I went from 370 whp stock to 402whp. RR Racing said the the ambient temperature which was 90° may have affected the numbers though. But it was also 90° when I did the baseline and I was surprised with the numbers so who knows, too many variables.
