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

Vacuum sealer bag with pump
Set name: 10 Jumbo
The storage bags are a nice size fit a lot of blankets and comforters with no problem and I have a lot of them. The problem I have is the pump they give you is ridiculous. Would take you forever to get all the air out. I use the vacuum hose and it’s still took some time but a lot easier than the pump they give you that’s why I gave a three stars instead of five.

Multiple size bags and easy to use.
Set name: 20 Combo
I was pleasantly surprised with how great these were. I chose these for the variety in bag size but I thought I would forever be using the hand pump. Very surprised it worked very quickly and the suction held. Would definitely recommend!

Works well!
If you have Omni S1 pro this is everything you could ever need to maintenance for it! I have it run twice every night and you can’t beat $60 to have several repairs several times! Totally worth its money and fits exactly as if bought new!
