What was your Gas Mileage/HP after Losing the Catalytic Converters

[dwmmatt23]

I think that I'd take the $70 per cat chance and have them put on by some body and see if it passes.

damn i wish i could do it for $70 per cat, the one shop that i found that would change them wanted like $275 per cat. I would buy them online and have someone put them on but everywhere i look wont ship them to california. anybody got any ideas of where i can go to get some good replacement cats that will ship them here?

Magnaflow has a catalog specifically for California cars. If I'm not mistaken, they can only legally be swapped out if your stock cat(s) are bad. A decent shop would probably do it anyways, especially since these are CA legal.

Get them from Summit racing. Find out what diameter you need and order them.
