Took the boat out yesterday without the new BpS exhaust on it and rode around about 2 hours and had to limp in cause i blew the welds off my Marsh Mellow exhaust flange on one side and the header pipe popped loose and it was the loudest racket ever. Glad i have the BpS exhaust to replace it. I'll have the flange rewelded just as a back up. Might have to cut open the Marsh Mellow exhaust and take the baffles out of it because it seams like there is too much pressure or something because this had happened once already but the first time it broke the bolts that held it to the engine broke and it fell off the slip flanges on the header pipes.
