Noise levels

pops · 31-03-2016, 10:07 PM

Looking at the noise level allowed for evenings at Donington and it is 98db.

Not over sure I'd get by on that with running a SS LWR back box and non - res SS centre pipe.

Anyone running similar and have any idea?

Secondly, could I just have a run up to Donington when there is a track day there and I'm home and blag a noise test? Or could I only get a test if I've coughed up for the day?

Not sure how it all works.

with SS LWR back box, SS Res Centre, a/m cats and oem cat i have never tripoped any noise meters in the UK inluding BEdford, Donny, Oulton, Rocky, Silverstone, Castle Combe, Snetterton.

Only place i tripped the meters was at Zolder, anbd that was after Curly in his Skoda shoppper tripped it before me so i ran aroudn at full revs in 3rd just to piss them off.

CSL at Donny is fine.

That 98db is also drive by.

I had that set up with supersprint cats and didn't trip it.

Put it this way. Bedford is very strict with a drive by of 88db ish so donny you could probably get away with a gruppe m.

I have race box and resonated centre section. Static at 93
Non resonated is louder?

i recall Woppum once got black flagged at Bedford with full SS and cats, non res. HE had done it maybe 5-10 times and one day he went above the BEdford limit

I hate worrying about track noise limits though. The exhaust mod for me was never about hp, it was about weight loss. I was perfectly happy with the stock sounding exhaust

I have the full Supersprint system from the headers back, with the light-weight race back box and it is 106dB static

. So beware, as it would seem adding the Sports Cats gives a big jump in noise.

When I last went to Bedford, they just laughed and wouldn't even let me try a drive by

Cats add 3 db, non res adds 3 db then the rest is your back box.
