RPi GT Exhaust '08 M3
Well, Eloy from RPi called me this morning and decided that he is going to make a full exhaust system for our car. Sections 1,2,3. Complete bolt on. Price will be 1100-1400 for the muffler section.
He will be using my car for two to three weeks for designing and dynoing the exhaust. Iím ok with that but he told me he would also need my car after the exhaust is on for about a week at a time after each month. Im not sure why they need my car so much. Is that normal for exhaust development?
