Another option is careful routing of your exhayst system. I ran my 3"
exhaust pipe through the 'X' in the middle of the frame and back behind the
rear axle (but still under the car). Then I had a separate piece with a
'turn-out' on the end which I could rotate to direct the exhaust note to
either side of the car, or down toward the pavement. I would always find
out which side of the track they had the DB meter on, then point my exhaust
away from it. I was always able to meet the 105 decibel level without any
type of noise restriction in the exhaust pipe.

TR engines can be loud. Louder than some V8s. It's been my experience
that
you can also help your self by knowing where any 'sound testing' occurs at
the track and then being a little sensitive as to how you go past it that
area. Perhaps you can schedule an up-shift at that point. Such options
are
open to vintage racers, who don't really give a crap who wins.
