Revolution 24x7, great fit as lots of adjustment. Made by Jettex, very quiet, could do with being a bit louder really in my opinion(but having said that if you go further and remove the lower cat and get a high flow cat down pipe this will make it louder!)

Scorpion do a lower de cat pipe (does not bring on the engine light)

Check u tube for videos
Remember any changes you make have the possibility of invalidating your warranty so I would leave the car standard until it is out of the warranty period. Lots of 2008 cars are having engine issues. See the hatch sticky in this section. The Prodrive upgrade uses a different back box and there is a performance back box available from Subaru so in theory a cat back exhaust should not invalidate your warranty but I would not want to put it to the test!

Hi,
Just keeping everyone updated on the power results from Cobra Sport exhausts, We have been testing the latest Subaru STI Exhaust system at Scooby Clinics calibrated rolling road machine.
The car only made 286 BHP on the first run with its standard exhaust (It should have made the 300 BHP figure) so we realised we were working with an under powered car in the first place.
It made 6 BHP gain from standard O/E exhaust to 3" bore cat back system, and 4 BHP gain from the 2.5" cat-back system.
Cannot wait to put the de cats on
A couple of links to hear the exhaust in action -
