Catless emissions

[bill silvis]

okay so I'm sure this had been asked 1000 times and I know the defouler answer but I'm not entirely sure on it I don't know the exact thread size on the o2 or the defouler. If someone could give me those sizes or what I need to buy or even link me to a thread with that info it'd be greatly appreciated.

The companies that make the catless downpipes have options to buy defoulers from them, or they come with a defouler when you buy the downpipe (depending on company). Did you already buy the downpipe

Yeah I've had it for like two years now passed last year but it was illegal and I need the defouler now I have a full race dp

It's always been illegal, and will continue to be illegal to run catless. The defouler doesn't help you in that regard. If you passed last year, you'll pass again without it.

you can order this if you really want one
