OK OK OK, I think I have everything figured out for my exhaust but one more question.

Should I just get the dual cat headers and dual cat exhaust system and keep my factory cats, or is it worth the extra cost to get all single cat components and get a high flow 3" cat?

Opinions welcomed!

 

A sinlge 3" pipe will outflow dual 2.25. It is easier and cheaper to just go with a true sinlge 3" set-up. That will be enough to support 350-400rwhp.

 

Personally I would keep the dual cat setup. You can also do what I did. Instead of getting 2 high flow cats, just gut your stock ones, put a pipe through them and whala. 2 high flow cats for the price of 2 peices of pipe. But...you will need to weld them back on your self as most shops won't touch it.

Good luck on your decision.

 

I would definitly go with the dual cat system True!!!
$500 plus is a lot of money but the flow and sound definitly make up for it!!!

 

P.S. We are now offering the #68470 WithOut AIR and a dual cat Y-Pipe which Hedman does not have in existance!!!

Price on this setup is $350 with an un-coated y-pipe this week
