Found this:

"It is very important to clean the exhaust system thoroughly after installation, as any dirt or debris will later be burned into the exhaust system. A contact cleaner can be used to clean the pipes, while for the titanium muffler outer sleeve we recommend using a multi-purpose spray lubricant (WD-40 or equivalent). The carbon-fiber outer sleeve should be wiped with a soft dry cloth.

WARNING! Do not use automotive wheel cleaners or any cleaning products which contain acidic additives to clean the front rosettes of Akrapovič Bolt-On exhaust systems.

If such cleaning products are used damage occurs in the form of corrosion of the ALU front rosette, which leads to the breakage of the inner flange which the muffler outer sleeve is attached to.

In order to get rid of dirt and buildup more easily, such cleaners contain acids which react with, i.e. eat into, the surface. The reaction gradually increases over time, which has a major effect on aluminum, which is very susceptible to the effects of acids. The compound of aluminum, acid and water leads to the creation of the galvanic effect, which results in even greater damage. This problem is especially acute because the flange in question cannot be thoroughly sprayed with water and dried. At first the damage is undetectable, but the chemical reaction continues unseen."
