CTS Turbo has been dedicated to manufacturing performance parts for enthusiasts by enthusiasts since its inception. Our continued development of the MK6 platform is not limitted to FMIC kits or Turbo kits, our all new 3" cat-back exhaust system is evidence of that. The CTS Turbo MK6 GTI 3" cat-back exhaust system is hand tig welded using the finest T304 stainless steel. Our exhaust system was designed for both street use and big turbo abuse. Our project Snowflake MK6 TSI uses the exact same exhaust for and will make 500HP+. Other MK6 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 MK6 GTI cat-back is ideal those of us chasing serious horsepower.
