Cracked Pipe

Not "crack pipe" but a cracked left side down pipe. Last year I replaced the left side, with the Flowsack (sp) for true duals and really liked the product. The system only replaced the the left side U pipe and right side streight pipe. Now I have a crack in the left side down pipe which conects from the U pipe and can't figure out how or why that happens on these beasts. Other than going to the dealer are there an ideas on a fix. Will JB wield hold? A friend of mine does not think it can be wielded because the metal is too thin. Anyone have the part number for this on a 2001 RK.

Seems to me, I recall that the mounting bracket was on a tech bulletin. Maybe someone like DAWG can give you specific information. I would PM him and ask. Also, pretty damn sure that a weld will not hold.

I'm sure you mean the Fullsac duals kit. If you are cracking exhaust pipes, I would look at fixing the cause as well as the pipe. JB Weld will not be a good long term fix, either weld it regularly or replace. You can post here on the WTB section or ebay and find a ton of take off systems real cheap. I would check your bracket on top of the starter to make sure it's not broke, check your motor mount and stabilizers and swing arm bushings, etc. as well

No on JB Weld. Yes on MIG or replace.

My crossover pipe shattered under the cover. I didn't notice it until a valve guide dropped out of the head at a gas station in the middle of nowhere, S.D.

dawg, oh master of the all known and forum guru, do you by chance know the part number for the down pipe, the one that connects the U to the muffler. Thanks brothers for the info, I had an idea JB weild was not a good idea. I did find that the bracket on top of the starter took a couple of cranks from the wrench; this also solved a horrable squeak I had. I guess if this brack gets loose it cause some problems. I found it loose when I blew out my U pipe last year, making me believe the vibration caused that problem. Did not think it was that loose this time but I guess it was enough to vibrate the pipe enough to now crack the down pipe. The Fullsac pipe seems fine, I guess a better type of metal than factory. Thanks again.

My Y pipe cracked all the way around right where the rear and front cylinders meet. It was still under warranty but there was a month wait for it. I welded the cracks with a wire welder and it held until the dealer replaced it. I'm not even a welder and it worked for me. I just cleaned it real good and tacked it all the way around then went back and welded between the tacks. It was a real mess, cracks all over it. I was missing the nut for the bracket that is above the starter (probably why it broke.).
