if it involves moving the converter, it's probably not allowed. They put the converters up close to the manifold for quick lightoff and better emissions, If you move it, it's not going to pass. I'm not sure if anyone makes headers that leave the converter in the factory locationSo, I want a new header, but where does the cat go? I don't want to purchase the header and fail my emissions test. please help!
I agree with this to a point. It really depends on the design of the header from the factory.if the cat is almost on top of the exhaust ports, there is no point in even running a header, the primary tubes couldn't even be long enough to be effective
So I hear.the issue is in places like Cali, you can't move the cat under the car, they won't even let you buy aftermarket cats unless they meet cali standards, that means one designed for undercar use will be illegal there, I have friends there and they tell me universal converters aren't allowed to be sold in the state, and you have to have a certified shop do anything to the cat, even replace it, it's stupid ridiculous there
Deleted cat = more noise just so ya know.Haha, yeah, I was literally just looking at eBay cat back header muffler combos. but the one problem I have with them, is I don't want my muffler to be a soda can and make my car sound like a P.O.S. I like how it sounds more.... "Racey", than "Ricey" if you know what I'm saying.
No.Were you referring to this header Fartbomber?
