Full Exhaust OBD
 

Looking to upgrade my exoticspeed catback exhaust to there full 3" engine back system. I know some people have had hit or miss with aftermarket midepipes, anyone know if there are any headers, or midepipes that wont through the OBD code?

Unless it has a cat, it will throw a code.

I have an RP supercat from rx7.com, you can also get a davesport high flow cat and weld it to your aftermarket mid-pipe.

The midepipe they sell has a high flow cat in it, but that still doesn't guarantee no codes
