View Full Version : Trapps for trials bikes

09-30-2009, 08:50 PM
Hi, I'm new to the forum, but not to SuperTrapps.
I am currently using one on a 1968 Greeves 250 MX with great success. It sure make tuning easier.
Question: I have seen small Trapps used on modern Trials bikes, like a stinger, for tuning/spark arrestor. But I can't find them for sale anywhere.
Does such a beast exist, or is my old age CRS just kicking in.
Thanks for your good products. Jim

You may be thinking of our 3M Steel DirtBike Universals;

Thanks for the reply.
I've tracked down a friend-of-a-friend that owns one. He says the disks are about 2.5 inches in diameter and the exhaust tube diameter is about an inch. The end cap is stamped as follows:
T99 SuperTrapp
Spark arrestor Forest Service Approved
Disco Jet Corp Division Davis CA ET Cycle

Does this shine any light on the subject?
Thanks again,

Disco Jet was a pre-SuperTrapp company name (a long, long time ago). The 3M product is going to be the closest Universal muffler we manufacture today, to the muffler you are referencing.
