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.

Durable and cute for a small breed or senior dog
Smaller han expected but overall seem sturdy enough for my dog who tears every toy he gets within a day so these have held up so far and no cleaning up of stuffing in my living room which is a plus. My dog loves them

So fun, so inexpensive
My almost year-old puppy absolutely loves these toys. They’re small and make this crinkly sound which she loves. I can’t believe the joy she’s getting from these little things that were so inexpensive. They’re suitable for dogs under 20 pounds I would say.

Super cute, didn’t last though.
Super cute, good size, I was hopeful that the durability would prove good too, but unfortunately our 7 month old lab pup made quick work out of them… 6 hours later and here we are, all squeakers removed and 🐰 & 🦆 no longer have a face.

Excellent for small dog!
These are very colorful and well made. They are flat, but wonderfully crinkly. Good sturdy material for medium to small dog. Looks like they will last a long time. My dog loves them.
