4" Redback Extreme Duty Offset/Offset Muffler Delete

The Redback Extreme Duty 4″ Offset/Offset Muffler Delete is a modular exhaust component designed to replace the muffler section in a Redback Extreme Duty exhaust system when you want maximum exhaust flow and an aggressive, un‑muffled exhaust note. Built in Australia from 409 stainless steel with heavy‑duty construction, this 4″ muffler‑delete pipe uses 4‑bolt, 10 mm thick flange plates for secure flange joints and is coated with premium heat‑proof paint to resist corrosion and high exhaust temperatures. Because it uses an offset‑to‑offset flange configuration, it integrates cleanly with other Redback exhaust components — ideal for custom exhaust builds or performance‑oriented setups where minimizing restriction is the priority. The delete option is backed by Redback’s 10‑year warranty, ensuring long‑term durability under off‑road or heavy‑duty use.
