Which is the best first mod to get the most power headers or catback??? Just wondering??

 

er cat-back by far..

 

I just ordered both :-D

But from what I've seen, the cat-back is the best to start with. Of course if you don't get a DynoFlash or something like an S-AFC, you may not see much of a consistent improvement due to the adaptive ECU in the Evo. Check the DynoFlash forum on here, it may be your best first mod!

 

You mean exhaust manifold?
