CSP regulations

I was interested in if running a straight pipe would keep me in CSP... I have a presilencer... the only thing SCCA states is if its to loud you would have to "fix" and make quieter. Thanks

I don't see anything in the rules having issues with the exhaust itself, only the noise i might generate. I believe they want it under 95Db at a certain distance

The exhuast is pretty free, in street prepared. The only real requirement is the noise level. I'm running a header, pipe, and a stainless "Fart Cannon" muffler, and my car passes (barely) the sound restriction. There's a couple other rotaries that are louder, a BP 20B and a ported 13B, so I have a little wiggle room. Being the SOLO chair doesn't hurt, either.......
