Yours has just the one litte hole for exhaust, some had a oval tube extension, and some had the 1/2 circle spring clip to open for priming the cylinder. This is located under the instructions sheets:

I don't know if these later used on RTF's, simplified to reduce production costs or were made from left over parts when Estes Engines folded and inventory bought out, or by Cox International, Canada doing an aftermarket production run.

We manufactured these as aftermarket accessories for the engines, modeled after the ones which were used on some of the later CL planes. While the ones with the extension pipe would be nice, we have not found a cost effective solution to making them at this point. Possible solution would be to eliminate the ratchet spring on the OD and press/rivet a extension pipe, but have other projects in front of that at the moment.

They looked quality enough to be a genuine Cox item prior to Estes. For the price of those who need mufflers, they are a good bargain. Regarding lack of exhaust pipe or streamlined exhaust pipe stack, I think that is more cosmetic than anything else, plus adds weight however minute.
