Tony, i do a lot of aluminum polishing on the side. I would need more info and or pictures to give you better advice on wha tyou need to do to bring it up to a propper shine. Is there a clear coat on there, is the pipe cast, has it ever actually been polished? Most boost pipes that i have polished for people have not been polished, they are just sort of "shiney". If this is the case (and i suspect that it is) then and normal amount of "wheel polish" will not work that great. You need to take the pipes off and "POLISH" them, either send them to a polisher, or buy the supplies and tackle it yourself, and you would need a bench grinder 2 different buffing wheels, 2+ compounds, cleaners, and possibly some sandpaper if they are really bad.
