Hey, it almost looks like I'm copying your setup - Eibach springs, Magnaflows, AEM intake....

....although I made my own shift ****....
Awesome dude

2.5 is to big. You will loose power over the stock piping. Read the back pressure article.

No matter what but the cat back exhaust will connect all the way up to your catalytic converter not to the headers
Correct, and most header pipes neck down a bit. Unless your engine is cranking out300 HP, there is no need to run 2.5 inch or 3-inch diameter pipes all the way back.

BTW, I just ordered a set of Magnaflows. Those and AEMs will go in during Christmas break.


Then that means they're just noise makers like intakes.
You can gain 10 HP with an intake and exhaust, but most of the gain will be at high rpms. Still, it's nice to have that extra punch when you need it.
