Three/four–Chamber Alu canister muffler with front inlet and front stinger
The short, "K-type" mufflers are thicker to provide the same muffler volume.
**/3 = 3-chamber
**/4 = 4-chamber
The 4-chamber design ( type */4) has typically 5dB(A) less noise, and slightly improved power characteristics.

These patented design mufflers are made of decent thickness material, and all parts are welded or soldered, so there is nothing that can start to rattle and cause radio interference.

Ball Headers (patents pending)
ballheader
At the moment only available in 25 and 28mm.

A ghost image showing the range of adjustment for the new style MTW ball header, which will make it very easy to adjust the header to fit the location of the muffler.
Sideways adjustment is possible as well to provide the height adjustment to your canister muffler.
The ball fit is tight, so it will keep its position when demounted for brazing. When fitting the prototype to my 45 MVVS, I was amazed at the ease of working with this system. I cut the header to the required length, lined up the parts and muffler as required, and then carefully removed the header from the engine, still attached to the muffler.
A few dabs of water-thinned flux on the ball seams, and the brazing was completed in about 10 minutes using a propane torch.

Mounting instructions:

After cutting the total header length to tuned canister and/or plane requirements, fit the ball header to your engine (picture 1). Adjust side offset with the first ball joint, nearest to the engine.
Next, align the end section of the header with the canister or tuned pipe (picture 2) , while holding the first section in position as much as possible.
Take the header from the engine without disturbing the joints, and braze the ball joints.
If done properly, the fit is exactly to your model's requirements, fast and easy.
