Simple, have a reasonable muffler on all the time. You won't get enough
additional horsepower from an open pipe to make being a pain in the ass
worthwhile (not that I think you are, Henry). There's an Alpha in my group
that makes a godawful amount of noise as he circulates at the back of the
pack. I'm sure he can't hear Peyote coming as I lap him--sometimes twice
in a 25 minute race.

Hi gang,
I need to work out a few issues that cropped up at the Jeff 500 before
Mosport. I need to run the car, and I guess either a chassis dyno or a
track day will suffice.
I can get 4 hours of track time or 1 hour of dyno time for about the
same
$$$. I think the track time is the better way to go, as I plan on
changing
out some parts for testing purposes, and I do not think I can get much
value out of one hour at the dyno.
The problem is the TR is really, really loud. The tracks that I can get
to
for testing have noise restrictions, looks like I need to be at or below
99
dB. At the Jeff 500 I had a guy tell me my car was the loudest in the
session. Doesn't surprise me.
I am thinking I want to have a very low restriction muffler for track
days,
and a bypass pipe for race days. I am concerned about how the different
backpressure will effect the engine.
So how do you guys handle this?
