I tagged along with Ned to Wayne's house to do some surgery on 950 ADV mufflers. The goals; 1. De-Cat a couple sets of ADV / SM cans. 2. Make a luggage rack for the SE. 3. Figure out how to mate a set of ADV de-catted cans to my old VFR I'm talking with Wayne about #3 and this is how the conversation went... Me; I need to fab up a mid pipe to mount 950 cans on my VFR Wayne; what year VFR? Me; '87 Wayne; no way Me; yes way Wayne; do you want a stock set? Me; uh, yeah Wayne; I have a BRAND NEW set off of an '86 Me; NO WAY Wayne; YES WAY Me; Woo Hoo Wayne had been hanging on to this set for years becasue he knew somebody would need them someday. Thanks for being a pack rat Wayne. I owe you big time, I'll come up with something this is Wayne, he has mad fab skills this is Ned, Wayne, and the new guy (whose name I can't remember), he came by to see the stich Wayne has for sale on this thread Ned; "So we are modding a 92 Goldwing trike for this years Baja 1000" New guy; "hmm really" while thinking, you're weird Wayne; "uh, he said Goldwing, cool!" exhibit A; stock 950 ADV muffler The plan was to sacrifice this one for the greater good. We know you all want to see what's inside right???? uh, how do you turn this on? Wayne demonstrating proper technique half way there pulling out the little bit of packing? / heat sheild? material that got caught on the sharp edges when it was removed. It was a big sheet of fiberglass or some similar type of cloth wrapped twice around the metal mesh inner layer cutting out the inner layer of mesh (outer skin, heat sheild material, inner mesh) almost there! Wayne said; "looks like a bong" Ned said; "note the flow pattern" so we concluded that the best way to de-cat it was to cut off the mounting flange, remove the cat completely, and weld the flange back on... mmm, tasty cat "I weld good" so how much does a cat weigh??? It was so light that Ned thought he needed to hold it on the scale so it didn't float away. After he let go of it... 1lb. Hope the internal view helps somebody. Couple of points to remember; the cat weighs 1lb If your going to drill / hammer it out without cutting the end off the can you stand the chance of the pieces falling down into the muffler and you will have a hard time getting them out If you cut the can open the best place to do it is just behind the flange on the tapered part so that you get the entire cat out instead of just the end of it. This is debatable but what we thought after we cut the first one open. Any questions, what did we miss???? As for goal #2... Ned and I played around with Wayne's sweet tubing bender and bent up some 5/8ths cromoly for a rack to keep Ned's soft bags off the exhaust and out of the rear wheel. the bender was awesome, it made it super easy to make two mirror image supports for the soft bags Neds gonna weld them up and post a pic for us.
