Product Details

Fits models without factory rear sports differential

Performance to blow your mind, not your ears! Improve performance and your vehicle's sound with this cat-back exhaust system from Milltek.
Milltek engineers took on the task of finding the perfect balance between maximum performance increase and a responsible noise level in each and every system, to appeal to enthusiasts of all levels. All products are direct replacements for factory exhaust systems, meaning no modifications are required for proper fitment.

This cat-back exhaust system is manufactured of a 2.50" T304 anti-magnetic stainless steel that is less susceptible to discolouration when compared to other systems found on the market. This quality T304 stainless steel is used on all of the pipework including the construction of the mufflers and resonators. Mandrel bending ensures full flow bends for better exhaust gas flow and Milltek systems are increased in bore to ensure the ultimate performance without the loss of mid-range torque. This exhaust allows you to retain the use of the factory exhaust valve system.

The valved mufflers reuse the factory valves from the OE system and seamlessly integrates into the car's vacuum system without any modification. The valve system is operated like stock through the Drive Select options. 

Kit Includes:

  • 2 post-cat down pipes
  • LH & RH front silencer replacement pipes
  • 2 Valved rear mufflers
  • Quad GT-100 100mm titanium tips
  • Installation hardware


All Milltek cat-back exhaust systems are covered under a limited lifetime warranty to the original purchaser for anti-corrosion and manufacturer defects.
