CTS Turbo has been dedicated to manufacturing performance parts for enthusiasts by enthusiasts since its inception. Our continued dedication to the MK5 platform is most evident in our new 3" cat-back exhaust system, which is based off of our 500HP+ MK5 GTI in the video below. The CTS Turbo MK5 GTI 3" cat-back exhaust system is hand tig welded using the finest T304 stainless steel. Other MK5 GTI exhausts that are currently available can choke peak power and limit the breathing due to their 2.5" construction. The 3" design of the CTS Turbo MK5 GTI cat-back is ideal those of us chasing serious horsepower.
