Perhaps anyone here has the information on installing Akrapovic Evolution exhaust system into the B48 engine? I understand that Akrapovic does not produce exhaust system for B48 engine, they only produce for B58 and S engine. But, according to the local installer, they can modify the front pipe to fit into the B48 engine.
The question is, if i put this exhaust system, will affect the performance of my engine?
