I want to replace by cars exhaust with a straight pipe from start to finish. Can I do this in the US?If not, can I at least remove all the pans except for the catalytic converter?I dont know if it matters but the car is turbocharged, has 1 catalytic converter and two independent exhaust pipes (each with its own pan).The replacements exhaust is not DIY. They are aftermarket but made for the car.
the only thank you to have an exhaust device with a cat is to get rid of it from the exhaust thoroughly. you will fail emissions so be sure you do no longer stay in cali or some place like that. It does not value plenty till you have been changing the entire exhaust device out.
OK, here is the law. It is *federally* illegal to tamper with emissions equipment. You can't subtract OR add to the number of catalytic converters originally installed in the vehicle. Stupid, but that is the EPA law, punishable with a $2500 fine, even you as the individual! Which is why most shops will NEVER agree to do a converter-less exhaust on the phone, so they don't get caught and fined. Some states do emissions visual inspections, others test the emissions output, and others hook their computer up to your car computer (if possible) to make sure there have been no failures. Obviously if there is no visual inspection, you aren't going to get caught. It's still illegal, but if you don't get caught Question one proves it: www.epa /compliance/resources/. Yes, it's old, that's how long its been clarified law. Read down to question 7, which specifically states you can't add or remove converters.
A cat converter is not required. REQUIRED is to pass a smog test, do that with a straight pipe and you're good to go, the fact that 80,000 engineers can't do it is not a factor. You MUST pass the smog test.
