I've had these on my 1998 VT1100CT since 2003. The right side muffler has just now rusted through on the bottom. I remember having to do some prying and maneuvering to get them lined up when I first installed them but nothing too bad. The full length heat shields cover the pipes and still look good to this day. I opted on the quiet baffles which have a very deep, throaty sound that's very distinctive and different from the tinny, high pitch sound of other aftermarket metric cruiser pipes. They do get a little louder over time but I still have the original baffles in. With the right side rusting out after 13 years it does look like I'm going to have to replace the mufflers. The outside finish still looks good but the rust started from the inside and there's about a 4" long by 2" wide rust hole coming through the bottom.
99 Vstar custom for me was a good riding, handling bike with decent power ranges :) But its missing that big bike sound and has weak spots in the acceleration ranges with wimpy deceleration.. Vance & Hines Cruisers to the rescue :) Sound is awesome !!!; Rumbles in town like the bad boy should. Performance has smoother range and the boy even jumps a bit on pick up now .. Varoooom.. Has that sound if ya know what I mean :D I could not have made a better upgrade.
