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: These systems are for vehicles with the Sport Differential.

Good grip glow ball
Style: Recharges, Size: Medium
Love this glow in the dark Chuck IT. Get a black light flashlight to charge the neon instantly. Good texture gives the dog better grip than the smooth all white glow in the dark chuck it balls.

Finally a Toy My Pitbull Hasn’t Destroyed in 5 Minutes
Color: Blue+Red, Color: Blue+Red
I have a 65 lb pitbull who destroys most toys almost immediately, so I’m always skeptical when products claim to be “indestructible.” Most toys last maybe a few minutes in my house before pieces are everywhere. These have actually held up surprisingly well. The material feels durable and thick enough to handle really aggressive chewing, and so far my dog hasn’t been able to destroy them like he does with most other balls and squeaky toys. That alone makes these worth it to me. I also really like the size. They’re large enough that I don’t have to constantly worry about him accidentally swallowing them or choking while playing, which is a huge plus for bigger dogs. The squeaker inside also keeps him interested longer since he usually gets bored quickly with toys that don’t make noise or bounce around well. If you have a strong chewer or larger dog and you’re tired of replacing destroyed toys constantly, these are definitely worth trying.

Excellent choice
Color: Red+Orange, Color: Red+Orange
I will skeptical when buying these because I have a pitbull bulldog that likes to chew holes in every toy. This is her favorite she choose on the ball, but she doesn’t actually ruin it because she can’t. It holds up one of the squeakers broke, but that’s expected I guess my wife actually ordered more. I’m not sure if it was from the same seller or not but those ones they don’t favor as much for some reason I seen the same different colors. My dog even sleeps with it sometimes. The picture shows for sleeping with it. I’m definitely happy. I got these. They are tough. I like the fact that they have those little recessed holes so they can grab a hold of it and not get it all slimy like the other balls we have.

GSD Winner
Color: Blue+Red
10/10 recommend for big dogs with a tough chew. Our GSD absolutely loves these squeaky balls. They have perfect texture for his teeth and for our grip. They are the size of a baseball and are so durable and fun. Yes the squeaky is LOUD but he loves them so much that it's cute
