any ideas on a new exhaust and downpipe for a STI TYPE R V5.
Not too loud but still wanting to gain horsepower!!!
Can you think of any comlications possible?
Thanks

 

The Revolution system gives good power and is not too loud inside the car. It is also good value for money at around £300 for the system. You can go with their D/P or an open neck 3" D/P from Roger Clark Motorsport or Hayward and Scott.
