i just got a riva freeride pipe and have discovered a hairline crack. its in the outer jacket just above the water intake nipple. i found it by preforming a pressure test (i.e put my finger on the exit nipple and blew into the in nipple.) the crack barely leaks air but if air can escape then so can water and im sure with a lot more pressure than my 40 yr old smokers lungs can produce. is there an easy way to fix this? would jb weld or similar product work?

When mine cracked I had the crack welded and it re-cracked first ride. Next repair we patched over the whole crack area with aluminum plate formed to shape the pipe, never had it crack again. You can see the plates in the pics

Ok. When people were talkin bout them crackin i thought it was bcause they were out bustin tricks. Im building a hull that came w/ tubbies and hull extentions and 3 pissers. I was plannin on routing water from the pump teed to the manifold and straight to the pipe. Then both head and the pipe to the existing pissers. Would the water b too cold and crack the jacket? Plannin lots of WOT runs in choppy water. I got an ada head w/33cc domes. Hoping for compression around 180lbs

The biggest reason why pipes fail after a crack is repaired is do to the lack of penetration. You need to drill the ends of the crack and open the crack up with a grinder so when your welding you get a key hole. Then using filler metal to bring the parts back together. If you just weld over the crack with out getting 100% penetration the crack is still there and aluminum doesn't hold up the best to vibration as a pipe sees.
