Hey,
So, I have some Z4M custom exhaust back boxes for sale. They are stainless steel with chrome tips, seem like a very well produced set of boxes. I purchased them from another member on here....they are 50% louder than stock, with some nice pops and crackles on overrun. I'll upload a video of these tomorrow, as I've put them back on the car to help sell them.
I paid £200, so happy to let them go for that price again.
