3.5in To 3in Reducers (pair)

The HOOKER 3.5in to 3in Reducer Pair (HKR11036) is a precision exhaust system component designed for vehicles requiring stepped collector sizing. This pair of steel reducers features a 3-bolt flange connection, enabling seamless integration between 3.5-inch inlet diameter components and 3-inch outlet piping. The black paint finish provides corrosion resistance in harsh underbody environments, making these reducers suitable for both street and performance applications where exhaust system modifications demand precise diameter transitions.

Each reducer is manufactured from durable steel stock with a robust 3-bolt flange interface that ensures secure, vibration-resistant mounting under engine bay stress. The stepped design minimizes turbulence during exhaust flow transition, helping maintain scavenging efficiency when downsizing collector diameter. The black powder-coat finish withstands thermal cycling and moisture exposure typical of high-heat exhaust environments. At 3.01 lbs per pair, the reducers add minimal weight while delivering structural integrity required for long-term reliability in demanding applications.

This pair addresses a critical need for custom exhaust builders, engine swap specialists, and performance technicians who require precise sizing transitions between collector and downpipe sections. Whether fabricating headers for engine conversions, upgrading factory exhaust systems, or restoring vintage vehicles with modern performance components, these HOOKER reducers provide the dimensional accuracy needed to match diverse piping configurations. The 3-bolt flange is compatible with standard exhaust manifold and collector mounting patterns, simplifying installation in tight engine compartments.
