105db to 98db silencer methods
Discussion
That's a real big job. The only way I've managed that is with a wodge of wire wool up the spout, and that won't last long enough. First check your silencer packing and redo with acoustafil if it needs it. I've tried all sorts of bungs and things in mine and the best results have been with decibel devils, which took 3db off. what sort of car is it?

Anyone got any suggestions or experience on how to get my 105db car down for a 98db track day ive mistakenly booked?
Ive been looking at combining one of these with some Silencer Packing:
but none of the manufactures quote any expected results, any one have any experience or suggestions?
I fitted something similar some years back to a 200bhp Caterham, it cut the power by at least 25% and I suspect did the engine no goodIve been looking at combining one of these with some Silencer Packing:

You can get a silencer that clamps on to your tailpipe. Not sure who makes em, but seen them on cars at track days.

Didn't realise the silencers suck so much power. thanks
The additional silencer probably wasn't so damaging to the power, these again it only got us down to 102dB. It was the insert which killed it (the noise and the power).If you don't want to lose significant amounts of power a new system is probably in order with a big silencer or two. Or book noisy test days like we do nowadays!

We had to lose 4dB from a racing Lotus Elan, we managed to do so with an additional silencer and a decibel insert but lost about 40% of the car's power in the process.
Didn't realise the silencers suck so much power. thanksGetting one or two more straight through silencers welded in is the best way to do it.
If you look at one of those things from a different view you can see why they reduce power:

Suggestions:
1. Call the track day organisers and plead ignorance/blindness/stupidity/keenness to do one of their track days. Many are reasonable and will let you transfer to a more suitable day. After all, they want you to keep coming on their days.....
2. Get the car tested so you know what it actually reads - most track day organisers will do this on a day they have an event running.
3. See if you can get a friend to take your booking, and book a different day for yourself.
4. Get some of these, but be very sure of the size of your tail pipes first - they will only fit straight pipes:
