Hey guys, I'm looking to get a custom made quad exhaust for my car the thing is for the dual tips to come out on the passenger side of the car there is a box? I know there is a couple companies that make quad exhaust for the 135i so my question is do they make the exhaust go around the box of do they move the box? If so can anymore provide me with details how and what has to be done. Please and thank you! Cheers
