Installed the 2.0 inch baffles on Chitlin's new SESG yesterday. Used the dremel with a grinding stone to remove welds on stock baffle--worked well and was easy to avoid damage to muffler body. Left the stock packing in the muffler, drilled 1/4" hole 1 1/2" from end and installed new baffle using a wood block and hammer to drive baffle in. Did 200 mile test ride and am very happy with the sound! Sounds like Rinehart duals but not quite as loud (and I don't think Rineharts are too loud). All went smoothly and everything went back together perfectly---mostly due to the advice and shared experiences here on this website! This forum has been a very valuable source of information, but I haven't yet decided what tuner to use. I think the guys at the HD dealerships have been told to always recommend their own product, and one service manager told me he didn't like the PC because it added more "connections"! Two others told me the PC has a high failure rate due to moisture. Right now, I'm leaning toward the Zipper's Thundermax w/ autotune over the PC V w/ autotune because of space, so it will probably be the Thundermax or the HD supertuner. But first I will install the Vance & Hines Power Dual headpipes--which I chose over the Fullsac "B" headpipes mostly because I don't really like the looks of the stock heatshields.
