I have a opportunity to buy an OEM 550 lower part of the rear Msport bumper in Carbon Fiber.
I own a 535 though!

I had a few questions...

1.Could i swap that lower piece out easily and purchase the 550 tips somewhere and have them put onto the 535 muffler?

2.Is this feasible without to much of a headache and cost$$

3.Can someone guide me through the process of making this happen!

4.Is this to much to do on a leased vehicle with having to change it back in a few years?

Thanks in advance
