i got longlife to look at this, and what with the 3" downpipe they said there wasnt enough room to do anything. I begged to differ but if they didnt want to do it then that was the end of it

What do you want to do with the car after you've had whatever system you go for fitted?

If its track days, what sort of noise limit are you allowed?

Long Life Bristol branch did mine 3'' turbo back with seperate WG pipe shouting at the floor

It will mainly be a road car with the odd track day

The noise limit is pathetically low, BUT they cannot test that when the engine is loaded up and the WG opens to let the screams out.

I love the sound of them, but they are a bit faahrty when the WG is just opening at onset of boost. One of those active exhaust flaps from ATP - controlled by boost is the right answer... The sound test is an easy pass then.

If i do the track it will be Knockhill.

Only issue is there isnt alot off room with a 3" downpipe.

Oh as for noise i have a 3" system with one box (side exit) it loud enough to fail the tests haha!!!

The noise limit at Fintray is 108db Raymor was there at the weekend see his thread

no noise limit at knockhill as far as i can see.

[Smith_S2]

yeah looks like your right, Looks like it depends on how much you car is worth

Craig that intercooler is massive, my G/F folkes stay in Abernethy when ever i head into Perth i'm always on the look out for your S4..... i'll find it one day!!!

Donington do a drive-by test and Doug has had problems with his S4 there.

IIRC Robo go rid of his as it was too much for daily driving.

One option is to route it rearwards and run a small silencer on it.

i have experience 2 cars with these both subarus.

the open dump with the 3" over a 2.5 with open dump gave 40-60hp estimated.

the noise is quite bad when at low boost but evens out at higher boost levels.

for out and out power then maybe but for the road its a no-no now im in my 30's

I did this sometime ago, good for a laugh but too much to live with. Way too noisy, for me at least.

Mark - your sounded brilliant on full song with that fitted... I can imagine how it could drive you a bit mad though all the time. Thats why I think the control valve would be nice so you could decide when you wanna make that much noise.

I intend to run mine out to the passenger side not the driver's side, should be easier to live with in that direction I think.
