The best place to start is with a high-flowing downpipe!
The factory Subaru downpipe is restrictive with small piping and a catalytic converter. This makes a downpipe the most restrictive part of the exhaust system, and the first place to start to improve performance. The solution is a PBMS high flow downpipe, made with 3 inch mild-steel piping and a catalytic converter delete. Possum Bourne Motorsport have designed and developed this to be a multi-purpose system to suit mild and wild power goals. It is a direct replacement for the factory downpipe and can be fitted to a factory 2.5 inch cat-back exhaust system (to keep the car quiet and stealth) with the use of the 2.5 step down adapter. It can also be used to bolt up to a full 3-inch cat-back exhaust system for those looking for more power. PBMS recommend using a high-flow downpipe on all vehicles looking for more power.
This is compatible with Subaru WRX STI Japanese Import GRB, GVB and VAB models from 2007 to current only. These are EJ207 (2.0L) powered vehicles equiped with a twin-scroll turbocharger. Please contact us if you are unsure. Please have your vehicle registration handy.
Once you get a taste for power, you may find yourself wanting even more! The exact requirements to make more power do vary between models, but Subaru engines respond well to further intake and exhaust modifications. Check out our range of staged upgrade packages to suit your Subaru.
