1. The Street Walker FMJ pipes are short, loud, mean, and not for the faint of heart. They will fit most Evo and Twin Cams and feature a two-into-one design with a flanged tip that really gives it a hot-rod look. The pipes come in either titanium or black ceramic finish and the heat shields are available in chrome, satin, titanium, or black ceramic. You can also order them with 02 bungs installed if need be. We chose a set of black ceramic pipes with gloss black heatshields ($895).
