Downpipes

Relieve exhaust backpressure directly at the turbocharger outlet, decrease turbo lag, and unlock massive horsepower gains with performance downpipes. Connecting directly between the turbine housing and the rest of the exhaust system, the downpipe is the single most critical flow restriction on any turbocharged engine. Factory downpipes feature narrow-diameter tubing, sharp crimped bends, and dense OEM catalytic converters that trap extreme heat and choke exhaust gas velocity—robbing your engine of throttle response, spool speed, and top-end power.

Upgrading to a high-flow aftermarket downpipe eliminates backpressure right where exhaust gases exit the turbo, allowing the turbine wheel to spool faster, bring power on hundreds of RPM earlier, and significantly lower exhaust gas temperatures (EGTs). Whether you're seeking a refined performance upgrade with a high-flow catted downpipe (utilizing 200-cell sport catalytic converters for clean performance and controlled sound) or setting up a track build with a maximum-flow catless downpipe, upgrading your downpipe is the foundational requirement for Stage 2 tuning. Explore mandrel-bent T304 stainless steel downpipes featuring cast bellmouth outlets, CNC-machined turbo flanges, reinforced flex sections, and integrated V-band connections across popular domestic, import, European, and diesel turbocharged applications.
