I Installed my dyna muffler yesterday following some of the good advice i found on this site. Something that helped decrease the angle slightly was removing the asbestos pad on the heat shield at the footpeg. This lets you turn the header pipe a taste outward.
I installed the dyna using a HD clamp. (bad ass clamp btw!) tight fit no slop but it leaked a little.
Enter this from Auto Zone>
Goobered alot all around the pipe, reinstalled the dyna and clamped her down TIGHT. Pay attention that you have the dyna rear bracket lined up with the rear support bracket.
A good man can get a bolt and nut in that rear mount and bolt her down.. I however, Am not that man lol.. I said screw it after 30 minutes but i see how it could be done with a smaller nut than i tried. Instead, A decent hose clamp from bracket to dyna support holds it good n tight.
You can reuse the S-40's big heatshield to hide your clamp and hide the exhaust goo goopy part. Looks ok enough for now.
Rode her today!!
Just 20 -30 min or so in city.. No leaks and i like the dyna sound alot! Not as loud as i thought it'd be but it sounds really good!!! I love it! Will put up a pic shortly of the results. Thanks to all who offered advice.
