[Fot] Mufflers?

[DAVE HOGYE]

I also have a spiral design muffler on my TR3.  It looks like a Cherry Bomb style glass pack without the red paint.  My car is pretty quiet, I've been told it's the quietest in my group.  I also have a Supertrapp slip-on to get it even quieter for occasional street use.  I run that with a lot of plates and the end cover.  

I've run events at Laguna where there is a bell curve sound limit...quieter in the a.m. and later in the afternoon without any problems.

I was told my muffler was a prototype from Edelbrock that didn't go into production.  You can see through it with the spiral surrounding the through opening.
