Speaking of mufflers. When we built a new car for the 2007 season for SG/SR I questioned the division tech director. My question was " What about the muffler rule and are they required anymore." I was told quite directly "NHRA does not have a muffler rule." I then said well only about half the cars running in the 2006 season in SG or SC had mufflers. Most racers had removed them. I was told again "it is a noise rule and not a muffler rule." I took it from the question and the direct comments that NHRA had no intention of enforcing the "noise rule" anymore. Therefore the new car came out to the races without mufflers and no issues with tech was encountered for the entire 2007 season and none in 2008 either.
I think the muffler issue is a dead one.
