Heading to laguna seca this weekend for the first time.

Worried I won't pass the 92 db limit - not that eager to swap the exhaust back to stock. This is a busy week for me at work and I don't really have a lot of time.

Does anyone have a set of silencers for an HKS hi-power?

I'd love to borrow/rent/trade for beer? If I lose or damage them of course I would replace.

I'll probably end up swapping the whole exhaust back to stock but this is worth a shot. It would be a big help if someone had some around they weren't using.

Thanks guys!

 

Ordered some universal silencers that should fit - hopefully this gets me in the safe zone.

Just realized my stock exhaust has a busted stud so I can't pop that back on like I was planning to.

Wish me luck on the DB check! Scott gave me some good advice on lifting after T5 but I worry about these roaming sound checks people keep talking about.

 

I came in at 98 DB with berk HFC's and HKS tru-dual exhaust.

I reduced sound to 92.6 or something and was able to continue racing the rest of my sessions without issue - I didn't get another sound check at the end of the day to see if temperature or environmental factors made me louder or quieter.

This is a link to the silencers I used: http://www.ebay.com/itm/201102121218...84.m1497.l2649

Quality seems fine and they reduced my sound by 5-6 db which is significant. I felt a minimal loss in power, though I feel like I was catching this one evo a little easier before I got meatballed... Could have been in my head though since the car was quieter.

Super happy with the silencers as they were way cheaper than the $50 a piece HKS wants for theirs and they went in easily. I did throw some tin foil on them to make them seal a little tighter. Removing them was way harder than putting them in. A coat hanger or something would have been really helpful.
