Brent;

I agree,I read some time ago (2 or 3 years) that a couple of tracks began requiring mufflers and had a decible (???) limit.... These cars where similar to the Busch cars in size/looks/power..... A couple of engine builders began expirementing with different headers and muffler combinations.... One shop found a combo that made the exact same hp and torque with the mufflers as it did with open headers,but he spent a lot of time and money on different combinations to get there.... I do not have the time nor the money nor the motor for this,but it can and has been done....

I just want to make some noise when I'm on the track!!!!!!!!!!!!!!!!! I may even switch back once I try it.... On the road course it is real easy for me NOT to have to watch the tach for shift points as I can tell pretty accurately my rpms with the noise of the motor.... After a few laps at speed,I then pretty much know approximately where I will be shifting..... When not in traffic I always watch the tach,but sometimes in traffic I'm watching my mirrors and just shift by the engine sound....

Also,nice big pipes coming out just in front of the rear tires just looks soooo gooood,kinda like the cool looking side pipes on a Cobra.......

Bernard,you are correct about pipe length and tuning... When I was with a dirt track team some years ago,we ran open headers with tail pipes..... A couple of top teams told me the way they determined tail pipe length was to use pipes longer than you would think and paint them with a cheap can of spray paint...... Where the paint quit burning off the tail pipe was the correct lenght or at least close to it.... We used that as a guide....
