Has anyone else had any trouble with the Barker Exhaust system blowing the exhaust air out of the joint where the head pipe & muffler connect? If so what is the fix. Mine did not do this at first installation, but about 5 hours into a ride yesterday it is leaking bad there..., and sounds basically like a straight pipe because so much air is passing through there instead of the muffler. Everything is still in the proper positioning & everything is still bolted solid & the spring is still in the proper place. Nothing is out of place or loose. I can't figure out what is going on. Anyone know?
