PBMS GRB/GVB/VAB Downpipe - 2.0L Twin Scroll JDM
Description
Want to push more power from your standard Subaru WRX STI V11 or V12?
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.
