Chuck, on my TR6 I use a Flowmaster muffler and I've been happy with it. It
is quiet and IO have always been a couple of db's below the sound limit. I
believe it is a http://www.flowmastermufflers.com/30_race.html and I know
they make a smaller single chamber if you want to be a little louder. My
car is quiet compared to most other racers.
On another note, not exhaust, I need to locate an air bleed valve for my PI
setup. What did you use or where did you find one? Mine fell out during a
race last year and I'm looking for a way to improve it a little.
Thanks,
Charly Mitchel
TR6 #44
