Well actually they are. But only quiet enough to meet race regs on noise
I don't like Supertraps for the street. They look odd and don't really do
the job people expect in the street environment. Exhaust tone certainly
isn't a design criterion for them, just getting under that limit is the
I have seen, or rater heard much better results from adapting modern
mufflers to old cars. They have small bodied mufflers that fit under MGs made
by the large manufacturers. I use a Magnaflow that has an OD of only 6"
diameter in the Jamaican, and it fits nicely between gas tank and leaf
springs. Most of these mufflers only come in 2.5" size as the smallest and
MG systems are only 1 7/8" or maybe 2" at largest even in so called sports
systems, but you can just use an adaptor on each end. If it is still a bit
too rorty for you, just add a small resonator tip to remove any residual
bark and you have a very nice street MG system.

Supertrap mufflers are not intended to be quiet. It is first of all
a straight through pipe with negligable restriction.
