May I ask you two questions? Since I am planning to do the quad exhaust and M areo kit.
1) What is the diameter of the tip for the Supersprint?
2) Do you need to cut the rear bumper diffuser the cater for the quad exhaust? I know your stock 550 came with the trapezoid tips, are the stock cut-outs big enough?
