Invidia Racing Cat Back Exhaust - Single Exit Titanium Tip - 2008-2014 Subaru WRX Sedan / 2011-2014 STI Sedan

Invidia Racing Cat-Back: Cannon Muffler, Titanium Tip, Track Intent

The Invidia Racing Cat-Back Exhaust with Single Exit Titanium Tip for the 2008-2014 Subaru WRX / STI is a performance-oriented cat-back built around a cannon style muffler and robotic-welded 101mm titanium burnt muffler tip. 304 stainless steel construction, 3-inch piping with 1.5mm wall thickness, CNC-machined flanges throughout, and OEM hanger locations for direct bolt-in fitment on the GR WRX/STI. The cannon muffler design and single exit titanium tip give this exhaust a visual and sound character that suits track-oriented builds.

Cannon Muffler Design — Aggressive Flow and Sound

The cannon style muffler used on this Invidia Racing cat-back is a straight-through or near-straight-through design that prioritizes exhaust flow over sound dampening — less internal baffling means less backpressure and a more aggressive exhaust note than a conventional baffled muffler. The robotic-welded 101mm titanium burnt tip finishes the system with a wider exit diameter that matches the aggressive character of the muffler design. CNC-machined flanges at every connection ensure flat, leak-free sealing throughout.

3-Inch Stainless, OEM Hanger Fitment, Direct Bolt-In

The Invidia Racing cat-back connects at the OEM downpipe flange on the GR WRX/STI and uses OEM hanger welded positions for direct bolt-in installation. 3-inch mandrel-bent piping with 1.5mm wall thickness throughout. New gaskets and hardware are included. No modification to the vehicle required.

Straight From Subispeed

The 101mm titanium burnt tip adds visual presence at the rear of the car that matches the system's intent.
