Looks like NHRA in a rare case came to its senses to some extent.

Still need to put a muffler hanger to your removable collector though.

Thanks for posting Earl! Saved me some money... as I was in no hurry to purchase the required tethers. I would have, before the first race. Now I'll go to plan "B".

Still... what's wrong with the tabs that weld to the primaries and the collectors, and are fastened with a bolt?  A muffler clamp and a bracket to the body seems like a make-work proposition...

X2 thanks for posting. Can't believe they changed their mind. I'm guessing to save face they couldn't totally backtrack from the idea, hence the supports. What's next, tethers to hold our tires on? Someone probably explained the futility of trying to tether everything that could possibly fall off the car.
