Have talked to a few people who run bottom mount kits in CA. Wondering if anyone is running a top mount single turbo kit in CA and how it’s going for them with smog? Not as much worried about the visual. I know in other states you can get a top mount single kit to pass smog but CA is a bit more strict. Looking for some insight before I take the plunge and figure it out myself.
