Want to get one as I am changing my exhaust to a GTC titan, I want to ensure it will pass sound checks.

Any advice as to a good value one to buy and do the testers just (for static tests) put it right up to the tail pipe?

I've got one you can try, quite a good one which I bought before Castle Combe last year :thumbsup:

Ive got a full professional one as it took me 3 months to pass Castle Coombe with my Radical and I got fed up of being turned away

Andy @ ACSpeedtech measured my GTC Titan, with downpipes, and I think static was 98db.

Sweet, david can I borrow yours seeing as we live closer.

Thanks anyway Limo

Good to hear Tom, was that with a straight through y pipe or silenced?

 

[Papa Smurf]

Had the same problem with the Milltek system, then changed to the Litchfield 102mm with silenced downpipes.

I am now below 98db on drive by and about 93db static with better spool up and great sound.

The answer is a Litchfield 102mm with silenced Y pipe and then all circuits can be used.

Its not the answer because I just bought the GTC titan :chuckle:

Not sure if the GTC Titan has a silenced version or not, it's fairly loud, sounds great and even better with the downpipes!

 

[Cardiff R33]

Mine didn't come with a y pipe so getting one fabricated

 

[TomS]

Ah ok, I've got the full system y-pipe included. Not sure if it's silenced or not though!

Ive got the full 80mm Titan with downpipes and its loud. If there is a silenced version, I'm pretty sure I don't have it. Does sound fab though but no way I'll be allowed anywhere near a track

 

[Wheels]

anyone got noise test data on the Akrapovic system as far a trackdays go.?

 

[Steve]

Don't change your exhaust system !!!!!

 

[deankenny]

I have never been to a track day, but the sound limits has always got my interest, why is it they put a limit on the sound?

cos they are t*ssers !!!

 

[deankenny]

They are reducing the customer base hugely by putting a cap on it, so either 1 of 2 things.

They either not too worried about business and happy how it is, or there is residency nearby and government laws apply with sound.

 

[Trevgtr]

Almost certainly the latter. Apparently years ago many tracks were built on 'spare' land adjacent to deaf and dumb hospices. The government of the day drew up legislation to protect their fellow MP's residencies
