high flows and emissions?

[uncleglenny]

has anyone here (canadians) changed their stock cats to high flows, and will they pass emissions tests?

which province are you in?


technically, a tech could fail you for the alteration to the emissions system when they do their visual inspection.

Most wont and will just hook you up to the hose.

i'm concerned because everyone says to take all four stock cats of and replace them with two maggies, just seems hard to believe that 2 maggies do the work of four stockers.

I had 4 on the Mustang, and replaced them with two.

Al I can tell you is, they're working for me. I also went with a mild cam, and the tune has something to do with it, but it passes.
