The Texas Speed 3" Cat-Back Exhaust System for the 2011 to 2014 Ford Mustang GT is a full T304 stainless steel system for the S197 chassis with the 5.0L Coyote V8. This is the non-valved version, built for owners who want maximum flow and an aggressive tone all the time. It bolts to the factory headers or to Texas Speed header systems and uses the factory hanger locations with bolt-on hanger mounts.
The system is made from 3" mandrel-bent T304 tubing with a 1.25mm wall and a brushed finish, with 12mm barbed round-stock hangers TIG welded in the OE positions. An X-pipe section and the non-valved mufflers are included, along with sleeve clamps in a dual-wall design that gives room to dial in fitment. The 4" TSP swivel tips adjust in both angle and depth and are offered in black or polished finish, chosen at ordering.

FAQ
What cars does the Texas Speed S197 non-valved cat-back fit?
It fits the 2011 to 2014 Ford Mustang GT on the S197 chassis with the 5.0L Coyote V8. Texas Speed states it is compatible with both the factory headers and Texas Speed header systems.

Both share the full 3" T304 stainless tubing, X-pipe, brushed finish and 4" swivel tips. The non-valved system has a constant aggressive tone, while the valved version adds valved mufflers, actuators and a control module so the driver can switch to a milder street sound.
What is the S197 cat-back made from?
The tubing is 3" mandrel-bent T304 stainless steel with a 1.25mm wall thickness and a brushed finish. The hangers are T304 stainless 12mm barbed round stock TIG welded in the OE positions.
Does the Texas Speed S197 cat-back include an X-pipe?
Yes. The system includes an X-pipe section along with the non-valved mufflers, all clamps and hardware, and the buyer's choice of black or polished 4" TSP swivel tips.
How do the swivel tips work?
The 4" TSP swivel tips can be adjusted in both angle and depth after the system is hung, so the tips can be centered in the rear valance openings. They are offered in black or polished finish.
