If you get a race header you will not need a high flow cat but you will need a flex-pipe. Then it will directly bolt on to your magnaflow after the flex pipe.

your race header will eliminate the cat completely...you do not NEED a flex pipe...the header will bolt directly into your stock flex...though i believe it is much better to get the larger diameter flex...just to be on the safe side...remember...your exhaust is only as good as the smallest part

Stock exhaust is made up of 4 parts:

Manifold--Catalytic converter--Flexpipe--Cat back

Using a race header replaces the manifold and the cat, upgrading to a larger flex is a good idea but is not required.

what about a shorty header? I've heard that those are better in the lower rpm/speed range (which is all I need for everyday driving.) Which parts do you need to have, and which are eliminated? Also, I think Maine has adopted Califonia's emissions standards, so I'd need to be legal.

With the shorty header nothing is eliminated except the stock exhaust.

shorty header goes like this: shorty header, hi flow cat converter,flex pipe,catback.

the shorty header replaces the stock manifold and it bolts to the stock cat or u can get a high flow!
