I've owned many harelys and changed many pipes. I kinda liked the Rinehart pipes originally but they discolored ..both pipes quickly. I bought another pair and same thing. With 4.5 they had a break-in smell and smoked when off but as of yet no discoloration. I changed from loud to a deep glass pack on a chevelle type sound. I like it a lot and hoping chrome holds to heat . They look and sound great.

Great pipes high-quality chrome easy to install exact fit for bike pipes look great and sounds great bike breathe a lot better now no longer stumbles below 2000 RPM I like that you can just take baffles out with two screws which makes them super loud I would highly recommend these pipes

Installation was super easy! It took about 20 minutes to install these, including unpacking them. S&S quality product! They look great and sound about as good as you'd expect from a slip on.
