[SOLD] Decibel Slayer trackday exhaust bung, used for barely a day at Brands

[Mankee]

I'm selling my Decibel Slayer as I've now got a permanent, quiet solution to my noisy car problem. I got chucked off Brands GP by 11am on a day there in June earlier in the year so had to buy this gadget to drop the static test result by 3 dB to have another stab at continuing the day. Don't get me started on the validity of static noise tests in relation to noise emitted under heavy load!

Some blurb on them on the JJC website:

JJC price is just over £70 plus delivery. I paid £70+VAT=£84 for mine in an emergency from the helpful chaps at Sevens and Classics. Two of the long bolts I've replaced with dome heads as I damaged the other two by grounding them down.

£SOLD!

Have to say this is a great bit of kit 

gets my R500 down to 100 db static

Duratec? How many revs is the 100 dB reading? I'm now down to 89 dB static at just over 5000rpm, so flat out past the meters at Bedford is pretty safe at last.

Does it have any noticeable effect on power output?

[Mankee]

I think it will do, but I can't be certain as I ran with reduced revs for the rest of that day. Best ways to find out for definite are to do back-to-back power runs with and without or just try it and see if you can feel a difference with the bum dyno.
