Pipecity

New type s owner in San diego county. I am interested in potential exhaust modifications for my Type S that won't effect my ability to pass smog. I am looking for something modest, a bit louder, and still relatively quiet while cruising. I would like to maintain the active exhaust/muffler however its not a must. I am curious about a couple options in particular. Either replacing the primary and secondary down pipes with high flow catted dp's or just replacing the secondary down pipe with a catless dp. Open to any suggestions and would love to hear what people in Cali are running for aftermarket exhausts.
