Feature:
1.The downpipe on your turbocharged vehicle is directing the exhaust gases out of the turbine housing into the exhaust system. An aftermarket downpipe will typically be larger in diameter and either uses a high-flowing catalytic converter or remove the catalytic converter altogether.
2.By removing the factory downpipe and replacing it with a high flowing unit you are allowing the turbo to more efficiently move gases away from the turbine which creates more power. Since the factory restrictions are now gone you can increase the boost on the vehicle as the factory downpipe is a choking point for performance.

I purchased this block-off plate kit for my Toyota 22RE engine, and it exceeded my expectations. The aluminum plates are well-crafted and fit precisely, making the installation straightforward. After removing the unnecessary smog components, the engine bay looks cleaner, and I've noticed a slight improvement in throttle response. The kit includes all necessary plates for the EGR and intake manifold, which is convenient. It's important to note that this modification is intended for off-road use, so be sure to check local emissions regulations before proceeding. Overall, this kit offers great value and quality for those looking to simplify their engine setup.
