Hey Im going to purchase the PPE headers sometime for my F. I was curious if there are any aftermarket companies that make a mid-pipe with a built in race cat for the F? Are there any companies that make straight pipes for the F with no cats? I see a lot of people have race cats welded into there stock mid-pipe.

Are there any companies coming out with headers for the F that could potentially be better than PPE?

thank you

Lowrider-

Roughly how much bhp you think with the PPE headers and hi flow cats the F makes? I understand temperatures and humidity and other things effect this, but i would just like an estimate. I'm getting the PPE headers and cats soon and i would just like to know how much power i should get. Also is this a noticeable gain? Also how loud is the Joe Z exhaust with these mods? I plan on getting the Joe Z exhaust later but I don't want something obnoxiously loud. What is your opinion on the Joe Z exhaust with these mods? Are you glad you chose it over the other aftermarket exhausts available for the F?

If i were to go to a muffler shop and get straight pipes made and welded in would there be a check engine light?

thank you
