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 is ideal for custom exhaust builders, engine swap specialists, and performance technicians who need precise diameter transitions between collector and downpipe sections.

Manufactured from durable steel stock, these reducers feature a robust 3-bolt flange interface that ensures secure, vibration-resistant mounting under engine bay stress. The black paint finish provides corrosion resistance in harsh underbody environments, making these reducers suitable for both street and performance applications. The stepped design minimizes turbulence during exhaust flow transition, helping maintain scavenging efficiency when downsizing collector diameter.

Whether fabricating headers for engine conversions, upgrading factory exhaust systems, or restoring vintage vehicles with modern performance components, these HOOKER reducers deliver the structural integrity required for long-term reliability in demanding applications. At 3.01 lbs per pair, they add minimal weight while ensuring effective performance in exhaust system modifications.
