The Texas Speed Full Header-Back Catted Exhaust System replaces everything from the cylinder heads to the tailpipes on the 2011 to 2014 Ford Mustang GT with the 5.0L Coyote V8, manual or automatic. It combines TSP 1-7/8" long tube headers, high-flow catalytic converters, a TSP X-pipe and a 3" non-valved cat-back with 4" swivel tips in one T304 stainless steel package.
The headers are TIG-welded T304 stainless with 1-7/8" mandrel-bent primaries and 3" collectors. The cat-back uses 3" mandrel-bent T304 tubing, dual-wall sleeve clamps throughout and TIG-welded 12 mm barbed hangers that use the factory hanger locations. Multi-layer header gaskets, plug-and-play O2 sensor extension harnesses, sleeve clamp adapters and all clamps and hardware are included, so the system bolts in without cutting or welding.

FAQ
What does the Texas Speed S197 header-back exhaust system include?
It includes TSP 1-7/8" T304 stainless long tube headers, high-flow catalytic converters, a TSP X-pipe, sleeve clamp adapters, a 3" non-valved cat-back, 4" swivel tips, multi-layer header gaskets, O2 sensor extension harnesses and all clamps and hardware.
What Mustangs does this full exhaust system fit?
Texas Speed lists it for the 2011 to 2014 Ford Mustang GT (S197) with the 5.0L Coyote V8, with either the manual or automatic transmission.
Is any cutting or welding required to install it?
No. Texas Speed describes the system as a direct bolt-on with all hardware included. The only noted modification is trimming the passenger-side heat shield stud flush with its nut if clearance requires it.
What is the difference between the non-valved and valved versions?
The non-valved system runs at full volume all the time with no valve controls. The valved version adds valve actuators and a controller to the cat-back so the driver can open or close the exhaust on command.
Is this exhaust system street legal?
No. Because it includes long tube headers and replacement high-flow catalytic converters, Texas Speed sells this system for competition use only. It is not CARB exempt and is not legal for use on pollution-controlled vehicles driven on public roads.
Are O2 sensor extensions included?
Yes. Plug-and-play O2 sensor extension harnesses that connect to the factory harness are part of the kit, since the long tube headers relocate the sensor positions.
