Welcome to the board mate.

I agree with the lads above regarding Supersprint. I've done Standard, GruppeM, 2xMilltek and now happy with Supersprint lightweight race for last 3 years.

No doubt the gruppem is the godfather of noisy exhausts. From cold it's down right anti-social!! the weight is incredibly light and the craftsmenship of the system is superb. Scratched that itch thankfully and now have the SS Lightweight Race system. :thumbs:

I take it the Super Sprint Race back box will be quieter than the Agency Power back box Kev wants to replace?

Indeed Marv, will the Supersprint be much quieter? I'm also slightly concerned about the noise limits at tracks?
So what would be peoples advice on a first track day in the csl? I consider myself a novice although i have done a couple track days in other cars at my nearest track which is Castle Combe.

I like the sound of my Agency power back box,don't think the neighbors think the same though:smokin:

Welcome along Kev, enjoy the car and the site! :)

quite a few guys run SS lightweight race Back boxes without any issue on track. When you start to 100 cell cat and/or de-cat the system it can get near the legal noise levels.

Mike R/Neil M/Shimmy/BillyboysM3/and a few others will have good info on acceptable exhaust combi's that pass track limits.

Ive had 100 cell cats, SS centre resonated, SS rear box race lightweight and never failed a static or drive by anywhere inc Donny, Bedford (I failed at Zolder when I buzzed he noise meters in third)

Hello and welcome :thumbs:

I liked the sound of mine with the full Milltek system and cats...

Hello, enjoy :beer:
