BMW 525 (E60) Universal

All of our BORLA® Pro-XS mufflers (formerly called BORLA® Turbo mufflers) utilize a straight-through design; we do not use chambers or baffles that slow down the flow of exhaust. As such, every one of our universal mufflers are reversible.

A center-in/offset-out muffler can also be installed as offset-in/center-out. The same holds true for our center-in/dual-out mufflers.

For custom needs, Borla® offers components of its performance exhausts separately. These premium upgrades are made from high-quality austenitic stainless steel. Use of these products may require changes to the OEM system or the fabrication of a completely custom exhaust. All responsibility for the outcome of such projects is assumed by the customer purchasing the product.
