John,
I have used the 25" Supertrapp muffler on my TR4. Apart from
sounding a bit like a "basso profundo" popcorn popper, performance
wise I rather liked what it did for my TR. You know you can vary
the loudness (and back pressure) by adding or removing the plates
that come with it (you get 6). The more plates the less back
pressure... The louder it gets the fewer the plates, the quieter
and the greater tha back pressure (I think I've got it right).
The only hassle I had with the Supertrapp was drag... I had to be
careful where I went, because of my 4's ride height. The muffler
hanging off the back of the tailpipe would drag going into and out
of driveways and parking lots with more than just a gentle incline.
When I had to replace my header, I went back to the 36" glasspack
and straight pipe (I couldn't afford the "plates inside" Supertrapp
muffler). The `4 is considerably louder now... (sigh).
