I had some JBW plugs in mine, too. You prolly noticed that I reused the stock mbz turnout. all I had to buy was the muffler and 2x 3"x 2 1/2" reducers. i used my portable bandsaw to make a bunch of miter cuts to route the exhaust lower and out the side. lots of fit, weld, fit, cut, weld and such, but I did it all myself
Also- I did take a bunch of pics of the mounts w/ measurements if anyone feels ambitious enough to go the homemade route on a TD hitch....
for $185, delivered(twice) I could not have done it myself......
