Main reason I was going to sell the Muzzy, it was I had the 2 into 2 Dekevic and it was all stainless. When I was cleaning on the bike I was just not happy with the 2 into 2 closeness to the bits. I was bored and decided I would see if the Delkevic muffler would fit onto the 2 into 1 and it did then I realized, "hey you can take that stupid long muffler apart, and cut it down". That was the main reason I was not feeling the 2 into 1 system I had in my possession. I cut 8 inched off the length removed all the paint someone sprayed bombed on and all over the pipe. I am pretty happy with it, over all. I am at a toss up at this point though to sell the 2 into 2 Delkevic or to keep it. Decisions decisions. It is possible that this 2 into 1 is actually a Delkevic with a muzzy muffler. I have had Muzzy 2 into 1's before and none of them where stainless, who knows, I don't.
Now for the bad. The piece that goes across the back side of the lower where that label was about the space between the abs and the pipes, that keeps the back of the lower not flopping in the wind, I had to cut it off. The fiberglass lower would have the very same issue. Mine I did a bit more unconventional as I drilled into the lower frame on the right side and added a stainless Rivnut and a stud with a spacer and an acorn nut and put it through my lower on the side. It seems solid. In my past on my very first ex500 that I did a super custom on I drilled a hole and spacer and has a sheet motel screw in it with a spacer, that always bothered me. Using the sheet metal screw was smaller, but it was something I had to watch a lot as I had to retorque the screw a lot. Some may scorn the drilling into the frame but I have had zero issue doing it, it might bite you in the butt so, if you do something like that take head that drilling into the frame thins the metal so to speak and can weaken it. In my case on this bike it is a salvage bike anyway and I am crazy this way. If you do it, again just be advised.
I might suggest buying some aluminum flat stock 2" wide about a foot long. When you fit the lower with that part cut out make the flat stock something that can be bolted and unbolted to go over or under the exhaust with a nice bend in it to clear the exhaust. Fix this where it can be used to support the tail pieces. These difficulties is the reasons that these lowers where removed by the most part. !0 years ago you could find these lowers all over the place in new condition for 25.00 all over the place and today they have rash and broken to pieces for 150.00usd not eve included the shipping. I would say it will not be long these once found everywhere bikes will no longer be found nor any accessories like the Streamline Airtech parts. Keep your work clean and know what you got. If you have a clean title bike that is not salvaged with clean parts, keep the original parts and experiment on fleabay and aftermarket parts. Otherwise just know you may be killing a rarity.
Anyway more pictures to come once my water pump mechanical seals finally show up. Stupid shipping issues of 2020-2023..not buying it but hey who am I, just the guy waiting on their stuff...
