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.

Really cute, well made dog toy. Was a huge hit with our pup
This toy was a big hit! Pros - love the heavy duty burlap-kinda fabric. Our new puppy has razor sharp teeth but this fabric is holding up really well. - size is great for a variety of breeds - shape is perfect for grabbing onto. Our puppy especially likes picking it up on the neck where the toy is more slender - the extra little feet and wing flaps add some interest that have really kept her occupied Cons - the squeaker is in the neck where the fabric has embellishments and is a little thicker. It's a little hard to activate the squeaker but maybe the toy/stuffing needs to get broken in more and then it will be easier to squeeze that section
