2008+ Subaru Impreza 2.5 STI (UK/EU) Performance Upgrades

For a number of months we have been working closely with Milltek Sport to produce a new 3” High performance exhaust for the latest UK and European STI range. This genuine 3” Turbo back system features 3 silencers, a Motorsport 100cell Catalytic convertor and stylish quad tail pipes. Not only is this system environmentally friendly it also helps release extra performance from the 2.5 engine whilst keeping a subtle but purposeful exhaust note.

As with all our Milltek systems it is made with the highest quality aircraft-grade stainless steel and manufactured to tight ISO 9001 quality controlled standards. The new exhaust also offers a substantial weight saving over original system.

New 2.5 STI engine when remapped to take full advantage of the exhaust systems free flowing design increases power from the standard 296bhp to around 340bhp. Torque also improves significantly with changes to the new variable exhaust timing and improved turbo response allowing the STI to generate over 350lbft from as little as 3,500rpm giving fantastic throttle response and overtaking power. The reprogramming of the ECU is also based on the latest Subaru calibration revision to insure the upmost reliability is retained.

The addition of our new 73mm Cold Air induction kit increase power even further with the engine revving more freely at higher rpm.
