Product Details

For Sportback Models Only

Performance to blow your mind! 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 2.76" T304 anti-magnetic stainless steel that is less susceptible to discoloration 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.
