I will be installing a set of Big City Thunder Monster baffles this weekend. If I mount the baffles the 6" from the end of the pipe per the instructions I will have to drill a new hole. What is everyone doing to seal the old hole in the exhaust? The only good idea I've come up with so far is a little exhaust tape with a new hose clamp over it to keep the tape in place. It isn't a perfect solution so any better ideas?
