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 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. 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.

Note: At this time, cat-back systems only fit cars without sport diff. Range of cat-back options for sport diff equipped cars available in the upcoming weeks.

Perfect!! I’m obsessed!

So cute and great for travel! Lots of organization areas, easy to use, very durable and not made cheap, the zipper closes just fine and it’s compact for traveling or storing under the sink.

Necessary for travel
Size: Medium (6.8"W*4.4"D*2.2"H), Color: Purple
This is really cute and looks classy. Quality is very nice. The only thing is the hooks for the necklaces didn’t keep them on, but everything else about this is a must for traveling and not losing or tangling up your jewelry.
