Customer Reviews


Nice pipes, I like that I haven't seen them on any other bikes. Good low end, but LOUD. If you want loud pipes get these,


The wrap was frayed at the top so I had to modify to make look good.


These look sick on my Fat Bob, they have a very deep loud sound. I'm really pleased with the look but make sure you like loud!!!


very nice pipes very loud


Easy install, looks great on bike.


these babies are loud as heck! perfect dound to them.


These are some very nice pipes. Nice low rumble at idle but scream when you crack the throttle open. You do deal with a bit more heat due to the wrapping and not shield. Install was easy on my 2013 WG only took about 45 min start to finish.

Blueing is caused by tuning characteristics, cam timing, carburetor jetting, overheating, etc. and is not caused by defective manufacturing. No refunds on exhaust pipes once motorcycle is started unless there's a manufacturer's defect. \ r• Flanges and retaining rings are not included with most aftermarket exhaust for 1984-2012 Evolution® and Twin Cam® models. Re-use your existing hardware, or purchase replacement hardware.
