Installing a high flow catback exhaust is a quick way to pick up horsepower and torque. A catback exhaust will also give your BMW E8X 135i N54/N55 a sportier tone. All Milltek catback exhaust systems feature a bolt-on design and mate seamlessly with your factory or most aftermarket downpipes.

The resonated catback exhaust features a center resonator and rear muffler producing a more refined and quieter exhaust tone while the non-resonated systems incorporate only a rear muffler and provide a louder more aggressive tone compared to the resonated systems.

Milltek Sport exhausts are produced in high quality type-304 aircraft grade in 2.5" stainless steel tubing. This quality of stainless steel is used on all pipework and the total construction of the silencer. Mandrel bending ensures full flow bends for better gas flow and Milltek systems are increased in bore to ensure ultimate performance without the loss of mid-range torque.

Available Tips: Polished or Black Cerakote

Actually Durable
Color: B) Medium 3" Ball
One of the few "heavy duty" toys that my pittie hasn't destroyed after a couple of weeks. Most of them last two days. She's an absolute beast so I'm confident if she can't destroy it, few dogs can.

Color: H) Infinity Ring, Color: H) Infinity Ring
Not for aggressive chewers! Done for in about two minutes. I unboxed this and tugged with my Mal for a but then let her have it. Within minutes she had chewed through it. Not worth the money.

Not Quite So Durable...
Color: B) Medium 3" Ball, Color: B) Medium 3" Ball
Maybe I have a SUPER aggressive chewer...he went through this ball in under a week. I originally bought the ball because of a review that stated the owner's Pitbull had the same ball for two years; not so much for my Rottweiler. He started chewing off and swallowing small crumbs from the ball within a day or two. By the end of the week, it was chunks so I had to toss it in the trash to prevent an intestinal obstruction. On the up side, my Rottweiler LOVED the ball while it lasted. However, I can't, in good conscience, give this ball a rave review based on this experience. Please take this review with a grain of salt as I have yet to find ANY toy that my boy won't DESTROY in a week or two. I hope that someone finds this informative when searching for chew toys for SUPER aggressive chewers like mine.
