I have an original Akrapovič exhaust, agency BMW, titanium color, installed since receiving the bike BMW GS R1250 2021 from Al-Naghi. For exchange with the original standard exhaust GS _ GSA, it must be in excellent condition from model 2021 onwards to be compatible with the internal system for air release and the Euro 5 emissions system that was introduced on the 1250 engine from model year 2021 and above. It has no scratches or defects whatsoever, in its original condition, praise be to God, with its invoice from BMW at the time of purchase and installation in the year 2021 AD.
