Thread: Pros and cons of going catless

Putting on sd headers as i write this. The cat almost looks new. Is it worth reaming out and going catless with the defouler trick or should I just put the cat back In. do I make any gains by going catless?

Thanks
Chris

The headers have a cat already installed?

No I was going to use the one that's in there already

In the factory dp?

Yeah I was going to make something up to keep the shell of the cat so it still looks like I have one

just go catless it'll be some work for that to work and you could scrap it if its not gutted

So pound out the inside and keep the dhell

pros being catless = better flow, release more powaa. cons being catless = your exhaust smells worse, and you have to deal with the O2. when it comes down to it theres not much difference, its all in whatever helps you sleep at night

no just don't use it at all

Hmmmm thanks
