if it's 105 db, you shouldn't have any problems.

I have friends with full akra and passed. Mine is stock exhaust with OEM bypass method and failed many times one the same 92 db day. Only to find out I was lifting too early going by the sound booth. Once I learned when/where to lift/gas, haven't failed it yet.

The sound booth is half way up the hill between 4 & 5. Look for the large tool shed like building to your right, can't miss it.

GL and have fun!!!

TIP: Gas at the track is $6 the last time I went on 6/3. If you don't mind leaving the track, there's a chevron 10 minutes away in Seaside that's super cheap and close by restaurants. I go there and grab gas and food during my lunch. Better food/gas, worth the 10 min drive.
