FlowFX Muffler 2.25in In Offset/Out Offset

The Flowmaster FlowFX Muffler 2.25in In Offset/Out Offset (Model 71235) is a universal-fit stainless steel exhaust muffler engineered for vehicles requiring compact, offset inlet and outlet configurations. Built with Flowmaster's proven flow-optimized chamber design, this muffler reduces backpressure while maintaining sound control, making it a go-to choice for custom exhaust builders, automotive technicians, and performance-focused vehicle owners who need reliable mid-range power delivery without excessive drone.

This muffler features a 14 x 9 x 4 inch oval body and extends 20 inches in overall length, accommodating standard piping at 2.25 inches on both the inlet and outlet. The offset configuration provides fitment flexibility for vehicles with tight underbody clearances or non-traditional mounting points. Constructed from stainless steel, it resists corrosion in salt-air environments and offers extended service life compared to mild steel alternatives. At 10.27 lbs, the unit balances structural integrity with manageable weight for installation on a wide range of applications.

Ideal for street machines, custom trucks, and enthusiast builds where OEM exhaust solutions don't fit design or performance requirements, this universal Flowmaster muffler works in conjunction with aftermarket piping systems, custom headers, and mid-pipe configurations. It's commonly paired with offset downpipes and adapters when integrating into non-standard exhaust routes. The natural stainless finish maintains appearance over time and pairs well with polished or coated piping systems.

Flowmaster's reputation in the performance exhaust market centers on balancing acoustic tuning with minimal restriction. This FlowFX design represents a mid-tier offering, suitable for builders seeking sound reduction and durability without premium-level pricing. Universal-fit mufflers require proper hangers, clamps, and adapters to complete the installation—verify compatibility with your specific piping diameter and mounting locations before ordering.
