Hey all, I have been doing alot of searches to help me figure out what I want to know. But I need more advice from you guy. I am looking at the:

MAC headers & Catted Y-pipe setup
SLP Shorties
Edelbrock Shorties

I have a Random Tech. Catted Y-pipe, so the SLP's and the Edelbrocks will hook straight into them and they are both 50 state legal. What about the MACs, are they 50 state legal and have all the emissions fittings? Also if the MAC's are 50 state legal, will they make more power then the other 2 setups?

I was looking at the AS&M Header and Random Tech Catted Y-pipe setup and I liked it but it's just a little too pricey and also I could find out if it was 50 state legal and had all the emissions fittings.

Please need help, thanks.

 

I would go with the SLP headers because they use 1 3/4" primaries.

 

AS&Ms are 50 state legal. They have all the AIR fittings that the stock manifolds have. You won't have to touch your cat at all during the install, so you should pass emissions no problem.

 

i think the macs are legal anywhere but california.
