We are now the proud owners of Chrisd306's high boost supercharged track 306 and had our first outing this bank holiday at Blyton in it. Awesome car and really happy with it, however did have a couple of small issues, one being if failed the drive by noise limit. Was recorded at 100 db on the static and drive by and the drive by limit is 95db.

Therefore looking for a quieter aftermarket flange fitment back box, something like a Scorpion as been told that the older ones are quite quiet. Wanting to try changing the back box as only need to drop it by 5 to 10 db, so what have you got? Anyone got any recommendations?

Thanks in advance.
