The Redback RBH724 is an unequal-length header set listed to fit the Subaru Impreza with the EJ20 and EJ25 engines, from 09/1998 to 2007. It replaces the factory exhaust manifold on those boxer motors, listed at $945.
What is the RBH724?
The RBH724 is an unequal-length header set for the EJ20 and EJ25 Subaru Impreza. On a flat-four boxer engine the cylinders sit on two opposed banks, and an unequal-length design routes each primary tube on its own path before they merge. Headers bolt to the heads in place of the cast factory manifold and form the front of the exhaust. This listing is the header set; the rest of the system is matched separately.
What's an unequal-length header and what does it change?
An unequal-length header uses primary tubes of differing lengths before the collector, which on a boxer engine is the design that gives the Subaru exhaust its characteristic uneven beat. It's a header — extractors — sitting at the very front of the system and an engine-bay job. Because it bolts straight to the boxer heads, the set is tied to the specific EJ20/EJ25 engines. We don't publish power or sound figures; the result depends on the whole build and tune.
Will it suit my Subaru Impreza?
It's listed to fit the Subaru Impreza with the EJ20 or EJ25 engine from 09/1998 to 2007. Confirm your exact engine and model with the workshop before ordering, since header fitment on the boxer engines is sensitive to those details.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men supplies and fits Redback headers across the Illawarra. We match the RBH724 to your EJ-powered Impreza, check clearances and flange fit in the bay, and confirm gaskets and hardware as part of the install.
