Can I make good power with cats?
I am looking at headers and y-pipe. Will my car pass emissions without the cat's even with a good tune? How much of a power difference will I get if I don't have cat's compared to if I do?

I wouldnt think you would lose that much through a good set of high-flow cats. Maybe 2-4 RWHP. I would gladly sacrafice the little power gain for the ability to pass emmisions,no rasp,and no smell. Good Luck

B-man makes over 420 with his set up, and it will pass with a tune, with good cats, but dont know how much it lost, but i would say 5-10 rwhp. I gaind 18 rwhp just taking out my stock cats. they accualy flow prety good.
Power can be made tho!

Passing without cats is no problem at all if you only have the OBD scan test. You will need cats if you have the sniffer test though. Many places (outside of cali of course) don't even do visuals....
