[DsilverM550i]

Shortly after purchasing my LCI M550i, I did the resonator delete. I'm relatively satisfied with the sound (for now), but no so much with the appearance. I'd like to install some nice quad tips, but from what I've read, given the short pipping from the muffler and limited diffuser clearance, only certain tips will work. Can I get some links (and pics) to tips that others have gotten to work with stock muffler/diffuser?
