14in L/W Muffler 3.5 In/Out

The 14in L/W Muffler 3.5 In/Out is a performance exhaust component engineered for serious engine builders and hot rod fabricators who demand compact, efficient sound management without sacrificing flow or response. Built by SCHOENFELD, a trusted name in racing exhaust systems, this muffler serves as the final silencer stage in custom exhaust builds where space and acoustic control are equally critical. Whether you're constructing a street rod, bracket racer, or high-performance truck, this compact steel muffler integrates seamlessly into tight underbody layouts while delivering the deep, refined tone that separates a quality build from an amateur installation.

This muffler features a 4.5-inch diameter steel body with centered 3.5-inch inlet and outlet ports, allowing direct bolt-on integration with standard collector and tailpipe diameters used across most V8 and large-displacement engine platforms. The 14-inch overall length keeps the unit compact enough to fit under heavily modified vehicles where traditional OEM-sized mufflers create installation conflicts. Black paint finish protects the steel construction from thermal cycling and road salt, while the internal baffle design effectively reduces dB levels without creating the dead, choked-off back pressure that plagues inferior budget mufflers. The 3.87-pound weight contributes minimal unsprung mass, making it ideal for performance applications where every pound impacts acceleration and handling.

Mechanics and fabricators restoring vintage performance vehicles or assembling custom engines will appreciate the universal 3.5-inch port sizing, which matches common header collector outlet and mid-pipe dimensions without requiring expensive adapters. Installation requires basic exhaust hangers and clamps; SCHOENFELD's proven design ensures vibration isolation and thermal clearance from frame and fuel systems on both street and strip applications. This muffler performs best in systems tuned for mid-range torque and top-end power, where aggressive headers and quality piping are already in place—it's a finishing component for discerning builders, not a standalone solution for stock exhaust upgrades.
