NASCAR's exhaust systems are bolted in at least 3 places from header to exit at side of car. Tab on collector and pipes have spring with washer and nut to allow for vibration. This was the way I did it a few years back and passed tech many times.

When was the last time a techman actually got down and looked under your car?

In NASCAR you put the car on jack stands and provide them with a creeper.

Mark --go get em--will be following your results---by the way is this EVERY car in EVERY class that does not have fully welded headers/collectors???- eventually NHRA will have tethers on most anything if ya let em get away with it--FED387

The staging lanes just need a nut checker like the golfers have a ball washer.

The spring system and the long bolt are currently use in NASCAR.

Here are options:

I am not shy and have no problem with that. Just be aware that I sanitize my hands by soaking them in the cooler.

The Wing tab kit would work as a final safety device, but this up to NHRA. Im bringing this collector with tab kits installed to Vegas with me, so wish me luck .... im goin in ....

From a technical perspective, due to the amount of the tab area that is welded to both the collector and header, wing style tab and the spring style tab would be the strongest.

I'm no techie but what do you think of the possibility of all the welds/bolts/springs/tabs/wing nuts in Mark's design failing ? REMOTE comes to mind !!!! The tether system as it appears totally eliminates "any" possibility of the exhaust system coming loose when installed & maintained properly and falling on the track that is the argument NHRA is probably gonna use whereas any one or all of Marks fastening devices "could" fail ( highly unlike that ALL would) and let the exhaust loose on the track--FED387
