Our Toyota GT86/Subaru BRZ Decat Downpipe replaces the standard restrictive downpipe and catalytic converter with a stainless steel, 2.25" one-piece decat item. Increasing the bore of the downpipe and removing the restrictive catalytic converter allows the exhaust gasses to flow much more freely, increasing the power output of the engine.
When tested with our Japspeed Toyota GT86/Subaru BRZ Decat Manifold, Cat Back Exhaust and AEM Air Induction Kit, our Toyota GT86 made 225bhp on the dyno after an ECUTek remap (the car originally made 202bhp in stock form on the same dyno).
