A single high-polished muffler with an extended GT-style tip gives the third-gen IS a classic GT look while keeping the tone street-friendly. Mandrel-bent stainless steel, dual 2.5-inch piping merged into a 3-inch single muffler section.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\u003cp\u003eAxle-back replaces the rear muffler section only, bolting to the existing mid-pipe behind the rear axle. The GT Single layout takes the factory dual exhaust routing and merges it into one polished muffler with an extended chrome tip, giving the car a cleaner, more classic look while still flowing significantly better than the restrictive factory mufflers. Tone is noticeably more aggressive than stock but not loud. this is the right choice if you want presence without drone or street-noise complaints.\u003c\/p\u003e\n\n\u003ch3\u003eCritical Fitment\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eRWD MODELS ONLY.
