It has been confirmed (NASCAR) that for 2007 the NASCAR CTS cars will NOT RUN MUFFLERS at all tracks except Kawartha at this point.
I give NASCAR a big 10 for this call.
Now that we know this is okay with the tracks I suggest strongly that the new OSS follows suit and gets rid of the Mufflers.
Lets make race cars sound like race cars again.

Yes Auto Assembler I do recall Scooter Scanell and his Zenith sponsored 99, but the best sounding car of all time was Harold Browns #10 1970 Chevelle (Blue and White).
I bet you didnt know this ??
Under the IRL Rule Book, Indy cars must run Mufflers, but it is only manditory in the garage area !!
Thats the only place I can see, or better for words- hear-, the idea that race cars need mufflers.

I agree with Mark re:CASCAR, either have them on at all the races or have them off at all the races for reasons mentioned.

Hey Dave, do you remember Howie Scannel's car scooting around the track at Flamboro back in the late 60's, the old yellow #99 426 Hemi, now that was a sound all of it's own!

  I sure remember the sound and I think it had more to do with the large diameter of the headers and the fact that the pipes ran back the full length of the car .  I am not sure but I think Brad Francis built the pipes for Bernie Reddick .

  I prefer a muffler rule but what ever they decide it should be one way or the other as having to have two sets of pipes just ads more cost for everyone.

That's the one!  ;D

Nice photo...do you have one of his Dart... If you do its rare beacuse the car when new, went through the fence at Flamboro in practice, and yes it did sound as sweet as the Super Bee !!
Hats off to Scooter Scannel....
