ISR Performance MBSE Axle Back Exhaust - Infiniti G35 Sedan 03-04

The ISR Performance MBSE Axle-Back Exhaust is a rear muffler section replacement for the 2003-2004 Infiniti G35 Sedan RWD. Large canister-style single-exit muffler in stainless steel delivers a deep, aggressive tone while bolting directly to the factory mid-pipe. The simplest path to a more aggressive exhaust note on the first-year G35 Sedan without touching the cats or anything emissions-related.

What It Does

Axle-back replaces just the rear muffler section, bolting to the existing factory mid-pipe behind the rear axle. Big canister muffler with a single 4.5-inch polished tip gives the G35 a much deeper, more aggressive tone than the restrictive factory muffler, while keeping the install simple and affordable.

Critical Fitment

2003-2004 G35 Sedan RWD only. The G35 Sedan exhaust hangers and mid-pipe routing changed in 2005, so this part will not fit 2005 and newer G35 Sedans. Not compatible with AWD models or any G35 Coupe.
