Extreme Duty 5" Straight Piped Resonator (Offset/Offset)

The Redback Extreme Duty Straight Piped Resonator (Offset/Offset) is a modular exhaust component designed to fit with Redback Extreme Duty exhaust systems for 4×4 and off‑road vehicles. It uses a 5" round straight‑piped resonator muffler body built from 304 stainless steel, delivering the aggressive, raw exhaust tone characteristic of a straight‑pipe — but with a more durable and purpose‑built resonator housing. The unit is coated with premium heat‑proof paint for corrosion and heat resistance. Its offset‑to‑offset flange configuration ensures compatibility with many Redback exhaust back‑bones and allows for relatively straightforward bolt‑on installation. Backed by Redback’s standard 10‑year warranty, this resonator module is aimed at users who want maximum flow, rugged construction, and that no‑muffler exhaust character while retaining a resonator‑style body — ideal for off‑road, heavy‑duty or “outdoor” builds.
