My three faves.

RS*R Exmag - full stainless, flat black painted muffler and angle-cut tip with rolled edge for stealthy look, nice sound but very subtle

Tanabe Super Hyper Medalion - full stainless, flat black painted pipes, polished oval muffler with straight cut tip and straight edge, little more throaty sound with a tiny bit of metallic rasp

GReddy SP2 - full stainless, no paint anywhere, polished oval muffler with angle cut tip and raised rolled edge, nice deeper sound between the other two
