And I can say, it was a ROYAL PITA in every extent of the word. We did no-weld way, which, worked however it took a lot of effort. First, we cut off the ends BEFORE the weld, which, proved to save our asses in the end. You get a lot of leverage out of them. The first pipe we tried to break the welds off. We got two out of three but left the assembly quite mangled inside. Then, my friend suggested cutting around the inner pipe where the fiberglass packing is. That worked well with a grinder and many, many dremel heads. Once that was done, the assembly wanted to come out but it was stubborn. Since the inside was mangled already, this took maybe an hour and a half of brute force to remove, plus much blood sweat and tears. The next pipe we did not repeat our mistake and cut the inners out to begin with. Went much smoother but it was still a pain. We found that it worked best when two people with chisels and prys, pry it out at the same time, and from time to time, cut holes in the baffling to gain leverage. It's still going to be stubborn though. This next pipe came out in about 45 minutes. The decorative caps are held in securely with the two screws, however, we did not use a sealer on it. I'm going to give it a little bit to see if it actually needs it, because at this point it's not a big deal (I can do this anytime). Be careful when hammering and chiseling, one of my pipes is slightly out of place, though it doesn't bother me because you can hardly notice unless looking for it. All work included, I'm guessing it was 4 to 4 and 1/2 hours total, with a dinner break thrown in. However, it's a COMPLETELY different bike now. It sounds a-fucking-mazing with hollow cans and virtually no dirveability issues as far as I can tell. I would suggest this to anybody who doesn't want to spend money on an exhaust, I think you'll be happy with it. This project cost me $0, not including the dinner I bought for my friend who was an immeasurable help in this (he did MOST of the work). This was by far worth the headache, and it seriously was a royal pain.
