BMW 6-Series Performance Exhaust Systems

Realize the full potential of your BMW 6 Series with a custom exhaust system from CARiD. Replacing the stock exhaust with an aftermarket 6 Series exhaust will instantly boost horsepower and torque, often by more than 10%. It is important to buy high quality performance exhausts in order to see the best results. CARiD sells the best quality of custom exhausts for the 6 Series in the market. If you cannot seem to choose between any two exhaust models, the knowledgeable assistants at the dealer store will help you make the right choice. For the highest gains in power, opt for either the BMW 6 Series MagnaFlow or Borla cat back systems. One great advantage in choosing a custom exhaust system for the 6 Series from CARiD is that they are designed to give multiple benefits, not just performance. A Borla, Flowmaster, MagnaFlow, Onki, RBP, Gibson, MBRP or Weapon-R 6 Series exhaust will give you greater horsepower and torque, alongside overall engine efficiency.

A new custom exhaust system will change your engine note, giving your 6 Series a more powerful sound. Remember that the older the car, the squeakier the engine note becomes. By replacing the stock exhaust with a custom one, you take care of this annoying sound and can enjoy listening to your engine drone just like before. Stainless steel and aluminized steel are the typical materials used to make the 6 Series custom exhausts sold at CARiD. The result is highly durable, rust-free and leak-free exhausts that are streamlined right from the catalytic converter to the tip. By buying a custom exhaust from CARiD, you will be making a one-off investment. Your custom exhaust system will serve you and your BMW for years, and you won’t have to replace it for as long as you keep the car.

Headers are installed because the stock exhaust manifolds usually flow poorly. An exhaust header has individual tubes for each exhaust port, allowing each exhaust pulse to flow unobstructed from the cylinder head. The tubes on headers are usually larger in diameter than the runners on an exhaust manifold and the tubes are mandrel bent for gradual radius bends.
