I have a question regarding swapping out the exhaust and cali smog laws. I just got a 97 miata in LA a few months ago, and it initially came with a similar exhaust setup using a universal cannon muffler, but I had the original owner remove it cause it was too loud. I want to put it back on with a resonator so it's quieter for the looks, and also in prep for my IRTBs. How do you guys take care of the smog check, and how often is it, every 2 years? I just had it smogged when I bought the car. Anyone care to PM me the secrets of smogging with mods on the car? I don't have the storage space to keep the OEM exhaust.
