Looking to change the whole system I have.

I need a 3'' through system, a 100 cell cat and a quiet back box, certainly no more than 99dBa.

I also want a light one!

Options:
Revolution do a system but the box looks heavy and the d/p looks to be a Ninja and a bit small in diameter.
H&S seem the fav with a bold claim to drop just 2 bhp across the cat system but is expensive.

Others like TSL are 3'' to 2.5'' so no good.

Anyone with any thoughts?

The car is an Sti V3 making 380 x 370 but plans are for a lot more.
I currently have a Magnex 3'' system that weighs a ton.(backbox) but is superbly quiet.
It must be quiet to pass track day/competition noise testing.

My Revolution 3 inch system with H&S 3 inch downpipe measured out at about at 96 dBa at scoobyshootout this year so plenty quiet enough, and thats with no cats, i would assume a sports cat would drop the noise slightly.

Can't comment on the weight as i have only comapred it to my old H&S backbox, it does seem a little heavy. Had you posted this a few days earlier i could have weighed it as i had it off to finally put some sealant in the joins!

scoobyworld do a lightish sports cat for that year. thats a 100 cell type + there only £299 new, tsl's are £399. there based in notts. i've got one for my car, im running a magnex system too

Ive a BPM Decat downpipe and had the metal sports CAT in the centre section which was legal and id imagine dident sap to much compared to full decat.

Thanks everyone!
Doug: have sent pm to GC8
Not sure how the quick release is done, but hope to get a pic. back from them.
Seen the bloody 4:444 diff they have after all my searching!!(cheap too)

Renno:
The Milltek is fab, but they only do New Age. Saw them at the Autosport Show last year and they can do a special which sounds dear and time consuming!

Danny:
I think AndyF runs a Revolution but a decat.

Trainer: Will have a look at their site now, thanks.

Graham, i immagine the quick release is in the form of a 'V Band' like on the big garrett turbos.

911

That's what i thought too.
Will be interesting to see what it is like and it might have an adaptor to the turbo, but i think it is for a turbo without internal gate.

The best i can find is the TSL motorsport system, but at about £1100.....

Anyone with experience of the Italian Supersports competition system?

I don't know if this will help but I have got a revolution 3 inch system sat down stairs, so I weighed the backbox using our new electronic bathroom scales, which said it weighed 7 kilos.

Thanks Damo, that's the same as the one i have!

I run a Milltek 3" with sports cat in the downpipe. Have seen 400+ on a dyno with it.

Certainly not noisy, use the car as a daily driver (20k+ miles per yr)

They are well made too, just they don't do a Classic version for some reason except to special order.

H&S all the way....

Drove one with a Milltek and found it to be too harsh on full bore....

Hi Graham, I've been looking at the kakumei 3" full system with a catted downpipe at flat4online. I was told it would pass MOT.

Being told it will pass the MOT and it actually passing the MOT are two different things, there was a thread on here recently where a guy had bought a sports cat and had been told it would fly through the MOT and it didn't. He ended up spending quite a bit trying to get it through the MOT before resorting to a standard system i think.

Graham - just bin the cat mate - then your options should be much better

Go on, where's the rebel in you

911

Nope!
Going green. Done the decat bit and smelt it last year from behind, like an old Morris Minor on choke...
Been pointed at a 3'' Graham Goode system which looks good.

Hope to find some at the Autosport Show in 2 weeks time.
I do actually have a 3'' cat but I'm not sure what cell/in2 it is.
Will pass the MoT too!

Terry: Us good guys have to lead the way!
