yup i got the result! Carbon Ti on 05 STi can pass db with stock dp below 93 dB @ 4500 rpm. i got my cert so i wont be bothered if i got pulled over for loud exhaust LoL just lettin you guys know!

 

Sweet. But, good luck if you get a downpipe.

 

LoL thats why you keep the cert so that they wont bother you :P

 

I know what exhaust I'm getting next..

 

^^ Good point/idea.

 

yeah i have some friends that got their cert to prove that they are compliant so i heard from them.

 

pure luck ryan it's cause your pinoy haha

 

hahaha i guess :P

 

I passed with the regular Hi Power. The carbon and hi power are essentially the same. I was around 93.7 dB. It did go pass 95 for a split second when they revved it up, then settled at 93 with throttle at constant.

 

how much louder is it mated with aftermarket dp and hi-pwr/carbon ti?

 

wait....so it wont pass witout a DP??

 

u won't pass dB test that's for sure.

The carbon ti has louder afterfire popping noises than the regular hi power when mated with an aftermarket dp though

 

he just went for noise certification. Nothing to do with emissions.

 

wow. what did they rev it up to?
My greddy evo 2 measured at 94.9lb (but I think they were too close. and they reved it to 4200)
I think they were supposed to do it at 3k right?
I didnt care because I passed anyways

 

no they said 3 quarter of the redline so mine is at 4500 rpm and yeah you wont pass the db test with an after market dp thats for sure.
