Cobra Aftermarket Pipe Fix for V-Star 1199's
A number of complaints were noted by purchasers of Cobra aftermarket pipes for the V-Star 1100. Specifically, the studs for fastening the stock pipes do not appear to be long enough to attach the Cobra pipe to the front cylinder exhaust studs--bottom line: the studs to not stick out far enough to comfortably screw on the retaining nuts for the collar on the aftermarket pipes. A number of fixes have included pulling the stock studs and putting on longer ones; changing the collar with one that matches the stock collar; relieving part of the collar that comes with the Cobra. However, the easiest fix has to do with the problem: The welding of the pipe where it enters the exhaust. A significant amount of weld bead is left on Cobra (and perhaps other pipes as well). This bead permanently impedes the collar from moving inboard to the designed position, wherein the weld bead was not accounted for in the design. Labree Motorsports.com solved the problem with a huge and hardened countersink. The collar is removed from the exhaust and the rear and in-board portion of the collar is countersunk. The collar is then reinstalled onto the front pipe. The countersunk collar is then found to be relieved sufficiently to fit beautifully over the weld bead. In turn, there are as a consequence of this relieving plenty of thread on the studs to allow full fastening of the front exhaust. Labree Motorsports is normally a custom shop for exhausts that require mandrel bending for automotive applications of all kinds. However, Brent Labree will accept the collars in person or by any mail method, pre-paid postage for $16.00 per collar. You could by your own countersink of the quality and size necessary to do the job, but such tool costs about $1,000. For an elegant solution that fixes the problem, the $16.00 plus two-way postage is a bargain.
