Go to New Hope Auto in Brooklyn. Ask for Roger. Shouldn't cost more than about $150.

Beautiful car, nicely done!
To keep the stock 550 muffler with the M5 diffuser, I used a muffler tip with single inlet and dual 3" tip output. The single inlet tip goes into the inner most outlet of the muffler. The other outlet of the muffler goes into the side of one of the tip. It's not perfect but it's a temporarily solution until I can find the M5 mufflers so I can install the 4" quad tips.

Dude.. you just saved me some bucks.. was going to get a new exhaust to fit the m5 diffuser due to the 550i tips not fitting the diffuser properly (mine are angles in right now).

Just hit up cyba for some of his black chrome tips and I am going to do what you did!!! Your sh!t looks nice man! I did the vacuum line delete and a resonator delete with X-Pipe and it has just enough sound for me without sounding like American Muscle.
