Black Rayzer on 2015 FLTRXS
This pipe fits exactly how it should and the finish is great. The sound is a little louder then I expected from the sound bites I had listened to on the internet. This pipe really changed the look of the bike and is an improvement over the stock look. I would recommend this pipe for anyone looking for a 2 into 1 on a dresser. There are others out there but the look and price of this pipe can't be beat.
