INVIDIA High-Flow Downpipe with Catalytic Converter – Bolt-On Turbo Upgrade
Maximize your turbocharged vehicle’s performance with the INVIDIA High-Flow Downpipe, engineered to be one of the most effective exhaust upgrades available. The factory downpipe—positioned immediately after the turbocharger—is typically the most restrictive part of the exhaust system. Invidia’s larger diameter tubing and smooth mandrel bends allow exhaust gases to exit with significantly less restriction, resulting in improved boost response, reduced turbo lag, and noticeable gains in both horsepower and torque.
Built to handle the extreme temperatures near the turbo, this downpipe features laser-cut cast steel flanges for superior strength and long-term, leak-free reliability. A high-flow catalytic converter is integrated into the design to maintain emissions compliance for street use—offering minimal impact to flow while supporting legal operation.
This downpipe is a 100% bolt-on installation for right-hand drive vehicles, with no cutting or fabrication needed. It also retains all factory O2 sensor locations for seamless compatibility with OEM and aftermarket ECU tuning.
