The MagnaFlow 17169 MF/R Series 5 in. Round body is a purpose built competition muffler kit engineered to survive and perform in the most demanding high output race environments. Its design and durability have been proven through extensive real world race testing conducted in collaboration with Camburg Engineering and validated under aggressive competition conditions by Camburg Racing. Its straight through perforated core, stainless mesh wrap, and continuous roving high temperature insulation fill form a two stage packing system designed to maintain unrestricted flow under sustained heat and pressure while controlling the distracting NVH that slows drivers down, verified through professional testing by Camburg Racing. Single piece billet 304 stainless steel TIG welded end caps with integral V band flanges deliver uncompromising rigidity, leak proof reliability, and the kind of mechanical stability required for repeated wide open throttle abuse. The 16 gauge 304 stainless steel tubular body features internal expansion capability and 3 in. / 3 in. connections, enabling 17169 to handle extreme exhaust mass flow, shock loading, and high cycle thermal stress without fatigue or performance fade. Fully reversible, it integrates cleanly into diverse layouts where packaging, flow direction, and thermal management are critical. Professional installation is recommended, and users should verify compliance with local noise regulations. For installation, the kit includes keyed flanges for precise orientation and V-band clamps for a secure, repeatable seal. Built from corrosion resistant 304 stainless steel and manufactured using CNC robotic precision welding, the MagnaFlow 17169 MF/R Series is a race proven, competition grade muffler kit engineered with direct input from off-road racing professionals and designed for teams and drivers who demand uncompromising performance.
