was going to do a few track days this year - but it turns out our local track has had a 95db limit put on it . which by all accounts is very low .
so my question is :
i've never had the car tested but is there any point of me even turning up to be checked with a full 3" nurspec on my piper 285/2.3 stroker:confused:
(even with the bung in?) - its a noisy bstaad at the best of times:D

My nur spec started to fail tests at oulton (105db)...with less spec than you,was 113db once!!...so i defo think you will fail.:(

The bung used to get it down by 3-8db,but i didnt want det with the bung in around track,as its mapped for no bung.

Hence why i bought a full nur spec rx:coolsm:...same quality only quieter:coolsm:....now i fly through noise tests easy

You can buy just the RX back box,but you still might struggle with 95db limit:(

Hope this helps.

i have toyed with the idea of something slightly quieter , but dont want to sacrifice any power either .
the blitz is brutal and the cops are big on pulling you for it over here too...:angel:
