High-Flow Catalytic Converter

Does anyone know a decent brand/place to buy one?

Will one of these cause me problems for emissions testing?

Oh yeah... also, is it worth the $$?

No point in wasting money, keep your stock cat. You won't notice a difference unless you got some heavy mods to your engine.

I got a generic high flow cause it was cheaper than a replacement stock cat. No noticeable gain. Hopefully it doesnt cause problems with emissions.

Okay good... I'm just gonna roll a stock one... Those hi-flow ones are pretty spendy anyways... Thanks for the input.
