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?
