I recommend painting the cans flat black before mounting. http://www.m3post.com/forums/showthread.php?t=540483
A little searching will show you how it can be a bit unattractive because the cans seem to be a bit bigger and visibly noticeable, yet not all that aesthetically pleasing like some aftermarket exhausts can be. (The pipes are gorgeous, though!)
