I bought a sj over the winter with a r&d dry pipe. I read alot of negative stuff about them as far as them cracking and was hoping to get it thrue the summer then buy a b pipe. It didn't make it till end of summer the front mount had broken at the welds. Should be an easy repair. The rest of the pipe is fine. I was wondering what everyones thoughts are on welding a tab on the pipe like factory pipe has with vibration mounts in-between the head and pipe. Would this prevent the cracking issues or is it a waste of time?
