CTS Turbo has been dedicated to manufacturing performance parts for enthusiasts by enthusiasts since its inception. Our continued development of the MK5 platform is not limitted to FMIC kits or Turbo kits, our all new 3 turbo-back exhaust system is evidence of that. The CTS Turbo MK5 GTI 3 turbo-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. Other MK5 GTI 2.0T exhausts that are currently available can choke peak power and limit the breathing due to their 2.5/2.75 construction. The 3 design of the CTS Turbo MK5 GTI turbo-back is ideal those of us chasing serious horsepower.Each CTS MK5 GTI downpipe is 100% tig welded, constructed using 3 T304 Seamless Stainless Steel, and includes stainless steel clamps.Lesser products can be had without stainless steel construction, or with seamed stainless steel, which can crack and decay over time.The CTS Turbo MK5 GTI downpipe eliminates the factory downpipe, increases turbo spool up, and peak power.The increased piping diameter of 3 allows for exhaust gases to exit the turbo and wastegate with less turbulence which all result in more power and torque throughout the entire powerband.In any turbo vehicle an upgraded downpipe is a great idea.Product Details: True 3 Stainless steel turbo-back exhaustn- Aggressive sound under hard driving, but subtle when cruisingn- Water jet cut flangesn- CNC mandrel bent stainless steel pipingn- Polished stainless steel exhaust tubingn- Adjustable 3 exhaust tipsTo remove the CEL that will occur, proper tuning software must be used.
