2015 - 2022 Ford Mustang GT


This exhaust system is for off-road use only and is not emissions compliant.

2017+ vehicles will require cutting and welding  at rear of x-pipe to axle-back exhaust due to a change in factory exhaust pipe diameter.



Texas Speed & Performance is proud to announce the arrival of the all-new TSP 2015+ Mustang GT 304 stainless steel 1-7/8" long tube headers with 3" catted x-pipe!

This system features all stainless steel tubing to provide our customers with the best possible products at pricing that cannot be beat! Why pay competitors $1,100 or more for a set of headers only? The TSP long tube headers and x-pipe are fully mandrel-bent on CNC mandrel benders for the best possible flow and accuracy possible! The system will include the necessary band clamps to connect our x-pipe to your factory exhaust system.
