if I put headers without a cat I know it will throw a code but can I ride around for a while without a tune? How bad will it hurt?

MPG will go to **** and you'll foul the plugs out sooner but it won't kill it if you do it for a little while

anyone know where I can pick up a cheap cat that will bolt right up into some speed daddy headers?

all cats are usable with headers. you just have to make sure the pipe sizing is right. have you installed the speeddaddy's yet? and what year is your car?

no I haven't will next weekend! It's a 2002 gtp

Ya? That's cool. But just order a cat and have it welded on...

any ideas on a place 2 order a good priced on?

no it wont. the rear o2 sensor, the one that will be picking up and throwing the code, will not alter air/fuel ratios.Originally Posted by benner
i drove around 4 months with no cat, and a CEL to go with it, and neither my city or highway mpgs were affected.

I have a catalyst ineficiency. Code and my air/fuel is maces out...

You will get the catalyst efficiency code if the rear O2 sensor is there and the cat is gone. If you remove the rear O2 sensor, that is where you will end up running rich in the 01+.
