SPDZ1 3″ High-Flow Performance Downpipe for 2016-2021 Camaro / 2013-2019 Cadillac ATS 2.0T

🔥 SPDZ1 Product Description

The SPDZ1 3″ High-Flow Race Downpipe is engineered for serious performance builds on Cadillac ATS and Chevrolet Camaro 2.0T turbocharged platforms, delivering increased exhaust flow, improved turbo response, and a more aggressive exhaust note.

Designed as a race-focused performance component, this downpipe is constructed from 3″ mandrel-bent 304 stainless steel tubing to eliminate exhaust restriction directly after the turbocharger — where flow gains matter most. The result is improved horsepower and torque potential when paired with proper tuning and supporting modifications.

Built for durability and precision, the SPDZ1 downpipe features ½″ thick laser-cut 304 stainless steel flanges, providing a superior sealing surface and long-term reliability under extreme heat and boost conditions. The turbo flange incorporates a machined O-ring groove, ensuring a tight, leak-free seal using factory-style mounting points.

Every unit is 100% TIG-welded for race-proven strength, reducing stress fractures and ensuring consistent performance under hard driving conditions. An additional O₂ sensor bung is included to support wideband sensors or auxiliary instrumentation, making this downpipe ideal for tuned and track-focused setups.
