Okay, I've got a Supersprint header and a Magna-deafening-flow exhaust. Since day one, I have been roasting the cat. It stinks to high heck. I'm sure it is getting blocked up. Should I gut it like I did in the VW days, or put in a race cat? I will be installing a Venom nitrous kit soon also. The Venom reads from the sniffer. Will a "test pipe" with the sniffer still in give me a problem with the Venom?
Someone...anyone...help.

yes.

I haven't seen any testing that indicates increased power from gutting your cat and you WILL have fault codes from doing so. Why don't you look into getting a high-flow cat that will still clean the air like this one that jlm has:

thanks, thats what I thought I got a chirp out of 2nd gear in my MC stock 03 :cool:

Yeah man, put a race cat if anything. It's really not cool to pollute the air more than what we are doing now.

anyone else open this thread expecting something else?

>>anyone else open this thread expecting something else?

I did...I thought, man, the cat is going to be pissed when he finds out he's about to be gutted! :lol:

Hi Bisch....
We did some testing on maxminis car, he has a borla race exhaust, moss headers and no cat. We took the car as is with
all those goodies on it and had it dynoed.... guess what he was 6 hp down on my car with only a supertrapp and a PB.

And to topp it of the ECU was throwing a fit......so on went the cat and we all are breathing better including the car.

Thanks for the replies. I know I won't gain power, I just don't want to loose power from a melted cat.

As far as air pollution, I live on the far east coast. All of my pollution just goes offshore....so it's okay. It's all you left coaster's that pollute my air! :lol: :lol:

For the love of all that is Holy, that was a joke, so don't start the flames! :lol:
