oooo wait my mistake, I have heard of these, just not for a while, they have that odd shaped resonator (its like angled of both ends and not squared off) apparently they're decent exhausts but make turbo cars sound REALLY odd... I think the member Golfin got one fitted some time ago... maybe ask him.
(still those power gains are not for the exhaust alone, they must assume supporting mods and map)
Ive got one.. and it does not add that much HP at all.. i think they missed the part where an accompanying remap is needed..
Ive got a video somewhere.. I love it..
Sucks (like a vacuume) air from the mani meaning it keeps the mani cooler for longer when the turbo gets hot.. and sucks all the rubbish out from the exhaust my car was blowing black cloudy smoke for the first day.. after a couple of days this has cleared up and the car can BREATH.. there free flow centre box is also amazing!
I had no grip otherwise it would have been a constand bellow!! in tunnels it sounds amazing.. people look very confused and ive scared off some big cars.. [:S]
You can fit it if you want, but that sound is created because of the turbo and the exhaust... but the apparent performance benefits of the vortex exhaust will help a n/a engine like yours too i'd expect - do a search on youtube, im sure you will find a sound clip on a car like yours.
