CL350 - Mounting new mufflers

[tacks]

Hi everyone, I've been slowly building my first bike from a basket case I bought mid-last summer. I've rebuilt the engine, painted the frame, and am getting ready to put everything back together so I can ride her as soon as the snow melts (if that ever happens) here in metro Detroit. I have new mufflers, Emgo Shorties, that I bought online and I was planning on cutting off my exhaust at the mufflers that have rusted through; then mounting the new ones in the same position and wrapping the exhaust. my main questions are these

1.) Is it as easy as cutting off the old mufflers, grinding down the chrome and nickel layers, and arc (only welder I have) welding on the new ones?

2.) I have put pods on my carbs and obviously the new mufflers will also change air/exhaust flow from stock, do I need new jets, or should I wait until I have her running before I determine this?

Thanks in advance!

It's easy to cut off the old mufflers, just be sure that you cut it where you have the room to mount the shorties (i.e. no interference with the rear shocks). You really don't have to weld the new ones to the headers, though. Most people mount them with a special clamp that usually comes with them. I actually just drilled a small pilot hole and put in a self tapping machine screw. Holds plenty tight.

I agree with BarnBurner, clamping or bolting them would give you more options down the road. You can weld if you want a more permanent setup, and do just as you said, I use a flap wheel on a angle grinder to just kiss the chrome, enough for a solid weld.

Take caution when wrapping these headers, I've had issues (and currently just repaired one on my 350) where the wrap with hold too much heat on these old pipes, and cause cracking.

I welded the crack, and came out alright, and plan to paint this year and not mess with the wrap. The wrap works better for a good solid steel pipe, rather than the thin chromed ones that come stock.

If you weld, I found the best way on these pipes is low heat, mid feed, and just tack your way around them. I let my tack cool before starting the next one.

Not sure if the CL350 mufflers are attached to the exhaust the same way my CL200's was, but if so then it's a PAIN to get off. There was a flange at the end the exhaust pipe and the opening of the muffler pipe, with a thick metal collar pressed over both flanges to hold them together. I had to cut through it with a dremel.
