I wanted a slip on muffler that gave an audible exhaust note. the stock unit was so quiet, all I could hear was the strange noises of the LC8 890 engine.\r\n\r\nI definitely did not want the excessive noise achieved with a cat delete. The RS-4 gives a nice deep tone way better than stock without the obnoxious noise levels of decat.\r\n\r\nIt is exactly what I wanted, a low, sporty tone without being too much.\r\n\r\nThe power seems to be better than stock. From idle on up, seems to pull smoother and easier. Cruising I'm often able to putt along in one gear higher than when stock.\r\n\r\nThe fit and finish are beautiful. Much better price point than other slip ons.\r\n\r\nOverall very happy with the product and my purchase!
Pros: Good quality components, good price point, achieved desired not too loud sporty sound
Cons: Pipe clamp could be a little more positive, like the stock unit. Slightly longer than stock length.
