High-Flow CAT vs. Stock CAT
 

i need to get a new cat converter. should i get a high-flow cat or just put a new stock one on? is there much difference?

Might as well get a high flow one if you plan more mods later on.

Just have flanges put on at a muffler shop.

I have a high flo on my hatch. It's:thumbup:

flanges??? what is that?

does a high flow cat cause a check engine light?

Flanges are the pieces welded on to the ends of the piping They bolt different sections to each other.

A properly installed high flow cat should not cause an engine trouble code.

I have a high flow on my car. They are probably cheaper than a OEM Cat or something, cheaper usually than most regular replacement cats I see.

high flow cat won't give you much in performance on a honda

do cats change the sound in any way?

A high flow cat will be louder than a stock cat, but quieter than a test pipe.
