So my question is should i mount her up or should i not even bother cause i wont have any back pressure. I only paid 5 bucks for it.
It will be loud and your performance may suffer. However my Dyna muffler (and I believe they all do) had what looks like an automotive freeze plug that directed the exhaust through the baffles. I believe any 1.5" freeze plug placed into the end that attaches to the header will put it back to normal. The inside necks down a little ways in and that is where it lodges. I used a piece of pipe to remove and install mine.
