These slip ons are fantastic. The chrome is high quality and matches the stock headpipe perfectly. They make the motorcycle sound like a motorcycle should without being obnoxious. Best price and service anywhere. A definate 10 on anyone's bike upgrade list!

I put this part on my '07 VStar 1300. It was very easy to install and I'm not mechanically inclined at all. It has a much better sound than the OEM muffler. The OEM muffler is much bigger in circumferance than the Cobra and had a big, 'beefy' look that I really liked. I wish the Cobra had the same look. Overall, I'm very pleased and would recommend the part.

Just purchased (10-25-2010) the Cobra Slip-On for my 2010 Yamaha V-Star Tourer. Wow is all I got to say!!! What a difference in sound.

Just the sound I was looking for. Not too loud at idle but when you get on it they will hear you coming. Nice throaty rumble at highway speeds. Thanks for a great product and prompt service.
