How to properly remove and install the rear muffler in an exhaust system on BMW X5?

With the exhaust system fully cooled down, raise and support the car for access to the exhaust system. Loosen the two spring-loaded bolts joining the left or right rear muffler pipe to the center muffler. While working underneath the rear of the vehicle, if necessary, unclip the rear bumper extension to gain access to the rearmost muffler hangers. Remove the left or right rear muffler hanger mounting bolts and then remove the spring-loaded bolts at the center muffler to lower the rear muffler. Exercise caution as the exhaust system is heavy and should be lowered with the help of an assistant. For installation, follow the reverse of the removal process, ensuring to use new gaskets and hardware while coating the hardware threads with anti-seize paste. Verify that there is at least 20 mm (3/4 in) clearance between the exhaust system and the vehicle underbody at every point. Loosely install the exhaust system mounting hardware and hangers before tightening the fasteners to their final torque. The rubber mount for the rear muffler at the rear subframe is color-coded by engine application, with the 6-cylinder mount being gray and the V8 mount being red, as mixing up rubber mounts can alter the exhaust system's vibration characteristics.

BMW X5 Muffler

The BMW X5 Muffler is an important sound-dampening and safety device in the exhaust system of the luxury SUV. It helps direct hot gases to the rear. It also dampens pressure pulses from the engine and helps reduce noise that might reach the passenger area. Within an oval or cylindrical shell, the Muffler pursues a pathway to its outlet through tuned chambers and passageways. Together, these features ignite destructive interference in the gas streams. In turn, this cancels the destructive effects of harsh pressure waves so that the vehicle stays below the legal noise limit. The device achieves slight back pressure which might pinch engine efficiency a little, but this trade-off is welcomed to keep carbon monoxide away from X5 passengers as well as neighbors. Particularly luxurious versions of the BMW X5 have the Muffler and an additional resonator of the same shape further towards the tailpipe to polish the exhaust tone. The difference is more one of additional quietness and not basic function. BMW has followed this pattern through the model years, so buyers will run into only two styles: the classic single Muffler layout or the dual stage system that fuses Muffler with resonator, both factory-tuned to BMW X5 performance expectations.

If you are looking for OEM BMW X5 Muffler, we highly recommend to shop with us. Not only do we offer budget friendly prices, but we also provide fast delivery. In addition, we have a hassle-free return policy on all genuine BMW X5 Muffler that come backed by the manufacturer's warranty.
