WOW ! Never heard of that before. But, I suppose that the extra back pressure MIGHT help certain combos.
So, do any of the quickest NHRA Stock & SS racers run a complete exhaust system, so that they can run a little quicker ??? 
There may be some, or lots of 'em. I have no way of knowing.

There will be a Super Stock car out next year that will have mufflers on it, along with a license plate, stock suspension and a 9" tire.
Not sure how long it has been since you have raced but there a allot of fast cars running mufflers. Muffler Technology has come along way in the last 15 years.
