Bum

I went with Dinan form my BMW modifications specifically due to their California Air Resource Board exemption and I knew that there would be no major SMOG issues related to using their parts. I didn't even think about that when I get my p-car as I did want to replace the exhaust at some point.

Does anyone know if the major companies (Fabspeed/A.W.E/Borla?) have this exemption here in CA? One less headache to think about and may even wittle down the short list even shorter.
