I've been wanting to attend track days at Laguna Seca but I'm worry about not passing the 90db sound limit for most track days. I have stock intake with 63mm test pipe and Mugen AP2 exhaust.

For everyone with experience at this track do you think I will pass sound with the current setup?

Thanks

Yeap you should pass, you shouldn't have to worry about tripping the sound police

Atlasm

Curious what makes you think I should pass? Do you or someone you know run a similar setup?

Yeah I took a ride in a friends ride with a Mugen exhaust and it's about as quiet as I can imagine even at wot.

I was just about to post the same question. I have the stock cat and an Invidia Q300 dual exhaust. I know that this is practically the quietest setup besides stock, but I still find it quite loud.

I would swap to stock just to be safe.

That's what I don't want to do ..

Anyone with actual experience at Laguna care to comment?

My friends cars (2 of them) both have not gotten flagged at Laguna:

They both have ASM s special 70mm single

Ap1 was equipped with berk 70mm Hfc

Ap2 with k&n fipk and test pipe as well.

What was the sound limit when your friends went? I know they have unlimited sound days, 102dB days, 92dB days, etc. etc.

90dB is quite low. I'd expect anything other than stock to be a problem at those level, but I can't say for sure first hand experience. I know of at least 2-3 people who have gotten flagged before - all with singles.

i would go back to stock to be super safe..at least to the oem cat. you don't want to mess with the laguna sound limit, especially since your track day was probably expensive relative to thunderhill and infineon.

or you can not be WOT going by the sound check booth..but that's no fun and you really want to be WOT going up the hill.
