Nicely done but a little advice, slightly increase your purge rate and allow it to flow through (don't seal it totally, a little bit more filler rod added and then overlap the weld at the start/end of the weld and increase the flow rate of the argon dwell after you have stopped the weld, as the weld cools it will absorb carbon from the atmosphere so by cooling it from the torch at weld end it greatly reduces this. Still, nicely done and far better than paying someone else to do it and it is exactly the spec you want (2 thumbs up)
Looks the biz. .. I've often wondered about converting the back of my 748 / 1098 back to 748/916 back end. It's the head f*ck and expense of making an exhaust fit. What's needed is some clever bender to make some link pipes to allow the 848/1098 system to be used, but follow the lines of the original bike.
That's the thing though it is an expensive piece of equipment to invest in and then every different size pipe, every different size wall thickness, every different size radius of pipe and every different materials requires a different set of tools and set up and knowledge of how to use the equipment. You can buy bends, best to buy trade and preferably food industry stainless (from a UK supplier to ensure you are getting the correct grade) and then with the see what you make, most engineering colleges will do a basic welding course, you want to learn TIG welding for stainless, MIG produces a ugly ass weld but it is quick and cheap (think about that the next time you buy an overly priced exhaust) and all that before you even think of making an jigs to enable remaking any exhausts you may want to sell. I am lucky as I use the right materials available, I am a coded TIG welder and I use a CNC hydraulic mandrel bender in my day to day line of work and yes I make my own exhausts when the boss lets me have time off... but I don't make them for a living. As an example in the pic below I had over 20 hours in making my headers for my Fireblade now multiply that time by a rate that a shop needs to cover overheads and make a profit to stay in business and even then it may not be as well made as you require as to the guy making it, it's his job not always his passion. Hopefully that may give you some insight or thought???
