I think when sterling marlin drove the 4 car and won daytona he ran them

Damion Gardner at Perris in April

I notice from the pictures of the Salute to Indy at Perris this past weekend, Damion had them on the car Saturday night also.

I would assume that they also considered Inertial Force as well. "With every action is an opposite and equal reaction." So when the force of the exhaust is pointed downward there is an equal force attempting to rise the motor out of the frame rails. Equalizing the drop or reversing the drop to a rise will eliminate or change that inertial force into one directed towards the ground. Kenny Weld attempted this in the mid 90's by turning his headers backwards and rising them up in an attempt to keep the front wheels on the ground. Ironically, one of the most famous pictures I remember of that car was of him pulling a MASSIVE wheelstand! LOL Theories are sometime best left a theory! Kudos on the R&D though, takes pioneers like that to keep our sport moving forward!

Karl had em many years ago. Have a set on the shop wall. Loud and hot. No mufflers then. Needed to be careful getting out. They were angled not really upside down.

This is the type of headers I remember Sammy having one night at Knoxville for a WoO show. This is Ron Jackson's Super mod from the eary 70's at 34 Raceway in Burlington,Ia.

Sammy ran thoses back on the gambler channellock car 

Kenny Weld once had left header on backward (rt side put on left side) so that outlet was straight out front of car.  Why???  Maybe just to confuse people?

kenny probley just ran out of left sides and only had rights left lol

Damian has actually been running them for a few years now

Really, that much?

But these pipes aren't zoomies, they run into a collector pipe thats pointing back & angled slightly up.

I'd like to hear the engine builder or crew chief's reasoning.....

He told me a few years back that he gets more power that way.

I would think header noise would be almost unbearable to driver

Lucas turned up at the Grove on night with a, set that stuck up in the air. They was banned after hot laps and replaced with the usual set. I heard there was a safety concern in the event the car wrecked and the safety crew would have contend with long piece of hot metal that could impede rescue efforts.

Yeah, was that in 2015? I know he was in the 5W that night.  I'm going to try and find a picture.

I went into the old Williams Grove Forum and dodged a couple of tumbleweeds, but found the the thread from the night Lucas and the 5W team ran the inverted headers. 

It was in 2015, but unfortunately the links to the pics of his car, which were close ups if I remember correctly, were broken.

Alas....

     Wouldn't shooting the sound up at the bottom side of the wing make for a wicked sound chamber?

I believe the thought process behind this header design was to point the exhaust air up under the wing. Down force is created when the air is going under the wing faster than the air is going over the wing, causing a low pressure spot under the wing and a high presure spot on top of the wing. I believe the theroy behind these headers is it would help "Push" the air under the wing, hopefully making it move faster casunig more downforce. 

To answer your question Murphy from a drivers standpoint, yes, that would be awfully loud. Heck, it is loud just the way it is lol. I had my ear bud fall out of my ear racing a 360 at Jackson one time and my ear rang for a couple days.

The Demon has been running them like that on the USAC #4 Alexander CRA 410 series for a cpl years now . They are bad ass oh yeah and we ain’t got no damn wings hehehe.

We need more sprint car racing at our home track.
