Noise levels on a 620 for trackdays

[james.c]

Hi all,
I think there are a few posts floating around on this but they're a few years old. I've only had my 620s for a few weeks and obviously(!) I need to book a track day for next year. Does anyone know if I'll have problems with noise levels? I assume it would be the same as the 620r although I didn't know if Caterham have done anything recently to effect the noise levels (I'll email them too).

Thanks,
J

I was under the impression that rear exit exhaust guarenteed all noise levels would be met- It was designed accordingly

Even the strictest ones ( Castle Coombe - Goodwood etc ) 

I do know that 105 " Noisey days" are not an issue

I have had  a 620R since 2014 and have never had an issue at Brands , Silverstone , Donnington , Cadwell ,Spa, Magny Cours, or Dijon .

Havent tried Castle Combe or Goodwood but all the static noise tests have shown figures in the low 90s region . I dont think you will have any issues most places with the rear exit system .

Side exit exhaust is another matter , one of the original owners recorded 110 (plus) drive by at Silverstone with that !

PS i suspect that the R is possibly a bit noisier than the S  in the peaks due to the flat shift which can cause a pop occasionally .
