TRUE....High Flow Cat?

redrider07 · 06-29-2007, 10:57 PM

Who makes a TRUE high flow cat for the 3.4 Alero? The reason I am asking is because the companies that have said the part number is high flow...is ACTUALLY just stock! I have looked up three converters that claimed to be high flow.....but they are just a stock replacement CAT.

Do you guys know of anyone...maybe Magnaflow...Flowmaster...etc who makes a high flow cat?

I'll be using the Magnaflow 3" spun Metallic cat for my new exhaust. Right now I have a Magnaflow 3" cermaic cat and I couldn't be happier. No "cat inefficiency" codes either.

So, that cat looks pretty good, and I am seriously considering getting it with my exhaust!

Have you guys ever heard of anyone taking off their cat completly, and is it worth it?

between a high flow cat and no cat there is only about 1 hp (or less) advantage to having no cat. i say its better to just stay legal w\ the high flow
