I have a bunch of new in the package MACS brand mufflers designed for profile planes. Have several different models to fit different engines. Mostly have OS55AX size. That one for example was $56. Selling it for $28. I used to own Outlaw Hobby Products and sold them online. I became a foster parent and had to get rid of the hobby business. Need to sell some of the old inventory so someone can have fun with it.

Buyer pays $5 shipping.

The MACS numbers for Profile plane mufflers were custom made for me so not sure. What engine does that fit? I will try to post the quantity and description sometime.

Boy I dont know if they will work for a gasser. They are designed for 2 strokes. If you know of a 2 stroke equivalent that has the same muffler bolt pattern I guess you could try it.

It was the YS .91 header if I’m not mistaken that fits the DLE 20.


Y.S. .90 &.91 SR, .91 ST (bolt-on)
(screws 4mm x 16mm socket head)
(center to center = 32.21mm/1.268")
These were the header numbers. 2985 2986 2987

You are absolutely correct on this! In the Mac's catalog, they used the part numbers 4200, 4201, 4202 for the DLE20, but the mounting dimension and aluminum tube diameter were exactly the same.

Thank you Jason for checking!

The Standard mufflers are angled for a standard engine setup like on a trainer airplane where exhaust is blowed under the wing. The regular price and the selling price are listed beside each one. Got pictures of each one available if you want a picture.

I'm interested in one or two that would work with an OS55AX. I have a couple now, but don't know what part number they are.

Which header would work best on a MadYak or a Primo? Give me a quote for one piece and a quote for two pieces shipped to Indianpolis, zip code 46226. :rockoncool:

Ok. The OS 1.20 mufflers I have are 48.5mm it looks like. The OS 91 mufflers are 42.5mm. Both are threaded mufflers that come with bolts. I do not believe they will work for you.
