NGX Motorsport S58 Catless Downpipes

The NGX Motorsport S58 Catless Downpipes are engineered to improve exhaust flow and reduce back pressure for increased performance and throttle response. Constructed from premium T304 stainless steel with precision TIG welds and an integrated flex pipe, they offer exceptional durability and an OEM-style fit.

By replacing the restrictive factory catalytic converters, NGX Motorsport Catless Downpipes allow the S58 engine to breathe more efficiently, resulting in quicker turbo spool, a more aggressive exhaust note, and performance gains of up to 25 horsepower and 30 lb-ft of torque when paired with the appropriate ECU calibration.

Designed as a direct bolt-on replacement, these downpipes are compatible with factory and most aftermarket exhaust systems for straightforward installation.
