The Softail Sport Glide comes from the factory with a 2-into-1 style exhaust system, so Cobra® decided to compliment this by creating two different slip-on muffler options. One is a 909 Twin, which uses the same scalloped, rolled steel tip as the 909's for touring models. This is a great sounding and affordable system. The next is a Dual Cut tip version which utilizes the same muffler body and tip as the touring model.
