2.5in To 2.25in Reducers (Pair)

The FLOWTECH 2.5in To 2.25in Reducers (Pair) are engineered exhaust system transition components designed to bridge collector or piping sections where diameter reduction is necessary. This pair of reducers serves as an essential solution for custom exhaust builds, engine swaps, and performance manifold installations where outlet sizing doesn't match downstream piping. Whether you're fabricating a street rod exhaust, adapting an engine bay setup, or optimizing collector flow into a single-exit configuration, these reducers maintain system integrity while accommodating size transitions that would otherwise require custom welding or complex fabrication work.

Constructed from durable steel with a 3-bolt flange design, these reducers feature a 2.5-inch inlet and 2.25-inch outlet configuration that allows smooth diameter transitions while minimizing turbulence and backpressure complications. The 3-bolt flange connection ensures secure, leak-free installation at critical junction points in your exhaust system, and all necessary hardware is included for immediate assembly. Steel construction provides thermal stability and corrosion resistance over extended use, essential qualities for managing the high-temperature exhaust gases that pass through transition points during engine operation.

Mechanics, fabricators, and automotive enthusiasts working on LS swaps, manifold upgrades, or custom exhaust systems will find these reducers indispensable for achieving proper component fitment without compromise. The pair configuration allows you to address diameter transitions at multiple points in your exhaust path—typical applications include collector-to-pipe connections, muffler inlet adaptation, or mid-system diameter changes. Installation requires basic hand tools and familiarity with exhaust flange assembly; the included hardware eliminates additional sourcing and ensures OEM-quality retention at each junction point.
