Laguna Seca Sound Barrier Requirement Concern

scruffydog

I'd be interested to know too...do you have HFC or TP b/c that would also increase the sound by a bit.

I've been wanting a F.I. non-res CBE for awhile but Laguna is the only reason I didn't swap it. I currently have Berk HFC and Stillen CBE (12" resonator) and it barely meets it. I guess in the near future if I could save up for the F.I. Non-res that can be my everyday setup and the Stillen can be my Laguna setup.

My friend's E92 Dinan Exhaust w/ a straight pipe does not pass the sound check and has to lift off every time at that turn - I guess worst case you can always do that.

Good luck with that!

Nope, just regular stock cats.

Leguna usually has track days were the limit is in the 80s, but at 92 I'm hoping I'll pass.

All you guys without stock are going to be close to limit or over on a 90 day. 92 days will work typically with some sort of resonated muffler system. Just depends on weather conditions and sound monitoring booth staff.

I bolted my stock muffler on my car with long tube headers and passed 92 db day.
