The Wehrli 3" downpipe for 2001–2004 Chevrolet 6.6L LB7 Duramax replaces the stock constricted downpipe with a full three‑inch section suitable for OEM charger or aftermarket drop‑in turbos. It is high‑temp coated and ships with heat wrap to help manage underhood temperatures. The downpipe is intended to improve exhaust flow characteristics where a larger, less restrictive path is desired.
