Exhaust noise level

[Fury556]

Hi all,

After quite the hiatus I've got myself another Puma (Ka turbo project still ongoing..). It belonged to a friend of mine and has the same Piper 4-2-1 mani and exhaust with 4" slash as my previous as well as being poly bushed.

I intend on going to Snetterton in a couple of weeks to take it around the 300 layout (did it in my 1.25 Fiesta and really wanted to do it in a car with some power!). I'm a little worried I'm going to breach noise levels. Has anyone been on a track day with this exhaust set up? The limit for this particular session is 102db static and 92db drive by (at 20m). If anyone has any experience with this setup, that would be very useful!

Thanks

Question answered at the track - Just incase the knowledge is useful for anyone else worrying...

with the above setup and standard sound test for a track day (0.5m at 45 degree angle) it produced 89db at 4.5k rpm. Well under the limit!
