Laguna Seca runners past and present, sound?
I usually don't like to do Laguna Seca because of the sound restrictions being so low (92db day), but an Oct 26th event offer is hard to pass up.
I'm not concerned about my exhaust, it's VERY quiet. But, I'm concerned about the noise of my MP62 @ 10 psi with FF tube and K&N -- it's noisey. For anyone that has run Laguna with MP62 and open intake, were you able to pass sound with the intake opened up? Thanks Rob.

larini 8" + Weapon r header will not pass sound generally. I added a ubend and a von hep to the end of mine and barely passed.

No worries on exhaust, I'll be putting my stock header and BOE/Phil's quieter muffler on -- I'll bring the cat just in case.
Primary concern is the supercharge whine from my MP62 @ 10 psi. Rob

oh ok you should be fine on the exhaust. I have a cup air box with the opening cut a good bit larger and am making ~11psi and passed ok. I think my exhaust was the bigger issue. I do think your intake sounds a bit louder than mine though.
