🏁What does a exhaust downpipe do?🏁

🐎In a turbocharged vehicle, the downpipe plays a crucial role by channeling exhaust gases from the turbine housing into the exhaust system. An aftermarket downpipe is typically larger in diameter, and it may include a high-flow catalytic converter or even eliminate the catalytic converter altogether for enhanced performance.
🦅Replacing the factory downpipe with a high-flow unit allows the turbocharger to more effectively expel exhaust gases, which leads to increased power. With the restrictive factory downpipe removed, you can safely increase the vehicle's boost, as the original downpipe often acts as a bottleneck that limits performance.
High-Performance Stainless Steel Downpipe for Maximum Power Gains
🚀100% Brand New, never used. Made from 100% Stainless Steel. Direct bolt-on fit to OE turbo or aftermarket turbo with OE exhaust exit. Eliminates OE catalytic converter for maximum exhaust flow. TIG-welded for strength and durability. Gains of +25 HP and +30 torque. Compatible with all factory O2 sensors and brackets. Straight-through design for maximum performance with easy bolt-on installation.
