What are some good high flow cats for my '05 4.6. yes, im in CA

 

Magnaflow makes great cats, but due to that California law, its gonna be quite a risk to get them $10,000 fine if caught.

 

they make em for CA... http://www.autoanything.com/exhausts...A3993A0A0.aspx

im just wondering what my options are or is it only magnaflows. i know they are excelent, i just havn't heard of any other high flow brand.

Also, many on here and other websites say that the OEM cats are already decently flowing. how much benefit are high flow cats. wondering cuz they are effing expensive!!! lol

 

Troyer has the same ones, for a lot cheaper!

Well, first off, contact Magnaflow directly and ask if hi-flow cats are legal in California. The answer will be no because they aren't.

And Ford OEM cats do not flow that good at all, the resonate so much sound, and slow performance down quite noticeably. GM trucks are the trucks with great flowing factory cats.

 

Give these guys a look. I got my maggie hiflows for $140 shipped.
