MagnaFlow 14616 6in Round Straight-Through Muffler 2.5in Inlet/Outlet Universal

Vehicle Fitment

• Universal fit - not vehicle-specific. Compatible with any custom exhaust system using 2.5 in. piping. Professional installation and custom fabrication may be required.

Fitment Notes

• This is a universal muffler - it does not directly replace a factory exhaust component without custom fabrication, cutting, and/or welding
• Designed for use in custom exhaust builds, single-muffler setups, or as a replacement in any system running 2.5 in. pipe diameter
• Fully reversible - can be installed in either direction without affecting sound output or performance
• Gaskets, hangers, and installation hardware are not included
• Professional installation is strongly recommended
• Note: Summit Racing indicates finish may vary due to running production changes from MagnaFlow (brushed or polished stainless)

Features

• Straight-through perforated stainless steel core design eliminates internal flow restrictions for maximum exhaust velocity and improved engine performance
• Two-stage acoustic packing - stainless steel mesh wrap over acoustic fiber fill - delivers MagnaFlow's signature smooth, deep exhaust tone
• 6 x 6 x 14 in. round body produces a fuller, deeper resonance compared to smaller-diameter round mufflers, with reduced interior drone
• Dyno-tested and proven to increase horsepower and torque by improving exhaust gas flow dynamics and evacuation efficiency
• Fully reversible design allows flexible inlet/outlet orientation during installation to suit custom routing requirements
• Weight-optimized construction reduces overall exhaust system mass without sacrificing durability
• All contact points are lap-jointed and fully welded to prevent distortion, cracking, or separation at the seams
• CNC precision robotic manufacturing ensures consistent core alignment and weld quality across every unit
• 100% stainless steel construction provides superior resistance to corrosion, heat, and road salt exposure
• Proudly made in the USA and backed by MagnaFlow's limited lifetime warranty

Product Description

The MagnaFlow 14616 is a universal 6-inch round straight-through performance muffler built for custom exhaust builds, system upgrades, and performance applications requiring 2.5-inch center-in/center-out pipe routing. Its large 6 x 6 x 14-inch round body is purpose-built to generate MagnaFlow's trademark deep, resonant exhaust tone - producing fuller, richer sound than smaller-diameter round mufflers while maintaining reduced interior cabin drone. The straight-through perforated stainless steel core, wrapped in stainless mesh and two-stage acoustic fiber packing, keeps exhaust flow virtually unrestricted for dyno-proven gains in both horsepower and torque.

At 20 inches overall length and fully reversible, the 14616 offers exceptional flexibility for custom exhaust routing. Whether used as a single muffler on a naturally aspirated build, a replacement unit in a dual-muffler system, or as part of a full custom fabrication, this muffler can be oriented in either direction without affecting sound or performance output. The stainless steel construction is fully welded at all lap joints for long-term durability, and the brushed finish provides a clean, premium appearance. Note that finish may vary slightly between production runs per MagnaFlow's manufacturing process.

This is a universal component - it does not bolt directly onto any specific factory exhaust system without custom fabrication, cutting, and welding. Gaskets, hangers, and connecting hardware are not included. Professional installation by a qualified exhaust fabricator is strongly recommended. The 14616 is manufactured in the USA using CNC robotic precision techniques and is covered by MagnaFlow's limited lifetime warranty, making it a reliable, long-term solution for any performance exhaust application.
