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.

Miracle

I wish I had before and after photos, my feet are in much better shape after using this. I still need to work on them more but I ran out pretty quickly but my feet were dry af. I used to “shave” my feet once a month this is the power of foot filing in a stick. I will never foot file again. I need to find a way to make it last longer but I think I will not need as much now that my feet are in better shape. Iykyk, get this. It’s greasy as all hell but it’s easy to apply and you can do it over a towel and then put socks on immediately before bed. I wish it was a bigger stick but it is not too pricy so it’s worth it.

Amazing how fast it works
Item Package Quantity: 1
This works so much better than the prescription cream I got from the doctor. I thought 40% was the highest available. Ease of use and it goes exactly where it's needed. Saw improvements after the second day of use.
