Re: Removing catalytic converter?

Allowing you restricted exhaust to flow better.. sounds louder.
Some of the cons are.. check engine light comes on unless you get mil eliminators or a tuner that can shut off your rear 02 sensors. Depending on where you live or what kind if emissions test are performed to pass your car for state inspection. Like if the garage.uses a sniffer or if hes a jerk and won't pass because of a visual inspection knowing the cats aren't there. I know some people replace the stock h pipe with non catted pipes, then swap them back to stock to pass inspection.... that's too much of a pain for me. I just leave my non catted h pipe on.

Re: Removing catalytic converter?

There are several companies that make high flow cats, and entire catted h or x-pipe mids with cats.

A lot depends on where you live and how they handle the emissions issues.

well, since I live in Florida and there are no law on emissions I'd rather just do a cat delete so I don't have to worry about it getting clogged again.

Re: Removing catalytic converter?

Without sounding like a tree hugger, keeping the cats intact or going to high flow cats won't hurt the air quality. And like back in the late '70s and early '80s, some engines won't work at peak efficiency without the cats.

Without sounding like an inconsiderate jackass, our motors run great with out them! And they sound great too! People in America worry so much about polution but they forget one little detail....THE EARTH ROTATES. Meaning that while we are freaking out, China is pumping out crap at higher rates than ever. Which means that as the earth spins we are just breathing in their crap, not the clean wonderful air everyone wants you to believe.

Sorry for the rant lol
