AEM V1, stock header, stock cat, JIC single (stainless piping with Ti muffler) - fails by a mile: 98 db and I was easing way off the throttle as I went by the sound station!

 

On the 98db at Thill, I'd call that a "probably won't pass" Remember that there's nothing standard about the sound stations at different tracks, and distance to the mic, offset, etc vary.

For instance, Sears Point has a sound meter too, but the placement is so good that the only car we've had fail it was a Trans Am car...and I'm not talking a gold chains, three buttons undone kind of Trans Am

 

I didn't have any problems with a K&N fipk intake, mugen header, stock cat, and J's 60rs. I'm not sure if the weather played a part, it was on & off drizzling that day, but for comparison a few stock c6 Z06s were getting meatballed.

 

lol - you talkin' to me?

 

Don't have to worry since I'm bone stock

 

my car would never pass the db test at laguna seca

 

Rylan got dinged for sound at Sears in April '05 with SV. I was in the sound booth at the time, so no he-said she-said

Oh and I used to have that kind of Trans-Am

 

Anyone know if a mugen exhuast + mugen intake would pass? I would assume so since the intake is pretty quiet.

 

Lots of stock cars will fail (Gallardo, Elise). Even my quiet ass evo failed. Lift between 5 and 6 and you should be fine if your car isn't obnoxiously loud. Laguna sucks because of the sound patrol. Bring lots of steel wool and some A/C ducting and a couple of fat metal ties in case you get meatballed by those mfers.

 

Two weekends ago I was there with the racecar (2.2 engine) with Comptech intake, test pipe and Spoon exhaust. Rylan saw the db readings, but I didn't, so maybe he can recall and post what they were.
