Polar Stainless Steel DPF/CAT Delete Race Pipe for 2020-2025 Chevy Silverado & GMC Sierra 1500 3.0L Duramax (LM2 & LZ0)
Maximize exhaust flow, lower exhaust gas temperatures (EGTs), and unlock maximum performance on competition-built diesels with the Polar DPF/CAT Delete Pipe. Stock diesel particulate filters (DPF) and catalytic converters severely restrict exhaust velocity, creating high backpressure that slows turbo spool times and traps heat inside the engine bay.
Engineered specifically for 3.0L Duramax LM2 and LZ0 inline-six diesel engines, this straight-through race pipe replaces restrictive factory emissions components with heavy-duty mandrel-bent steel tubing. Designed without sensor bungs for clean, streamlined racing setups, it includes heavy-duty stainless steel lap joint clamps to ensure a tight, leak-free connection under high boost conditions.
