To me, the critical question is "does it affect weight transfer and launch?". If none or minimal, go for it!

To me, the critical question is "does it affect weight transfer and launch?". If none or minimal, go for it! Thats how i understand it. You have to have the power to keep enough weight transfer for traction. So it becomes a balance of cg position and torque that can sustain weight transfer. Look at a modern prostocker launch versus a high ten second bracket door slammer launch. Then consider where thier CGs are and torque available for the first 10 to 20 feet.

It helps with aero. May or may not help with ET. Looks faster. Be interesting what effect just that exhaust location might have on aero, vs say slightly turned up, thru the hood, etc
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

Make the car move forward, not up. Upward motion is wasted energy. At least, that's my experience in motorsports.

My junk liked the chin spoiler in the front and I drilled holes in the rear valance for air to escape both helped in et and mph a bit......

Interesting responses.....Lack of empirical data makes this mostly opinion then....So here is my understanding:
I used to race RC cars, specifically Dirt Oval as a sponsored driver, and they are not moving at 150mph, but aero plays a huge affect on handling and stability. A good handling car makes faster laps and generally finishes higher in the standings...Even at relatively low speeds like 30mph....
So when I look at my Duster, it sits higher than my Cuda and couldn't be lowered due to the headers. Now that those are out of the way, I can now lower a bunch.....What the results are, I have no idea.
My plan is to lower it, and put a chin piece on it....and then get it re-scaled and the IC changed if needed..

Well my thinking, and NOTHING matters except what a Wind tunnel indicates and a time skip proves, is the directed exhaust out the side in the OP's location could have significant "air curtain" effects on the side skirt area of the car that "could" be very beneficial, at speed, where traction is less of an issue.

I know most of your racing is 1/8th mile where aero mods will have the least effect. Ideally I think you need to test it with the new headers before you do anything else. Just to see if they help or hurt performance.

I get what you are saying but a Duster is already blasting a pretty big hole in the air as it is, not tons of air on the side of these cars I am willing to bet.

Yes, 1/8 mile would likely show minimal bang for buck with aero, but how much does one need to be ahead of the other guy to win?

Where are you going to install the o2 sensor and your idle and low speed readings are going to be heavily skewed......

I asked him to install one on the passenger side. Typically with short headers and no mufflers you really don't get an idle reading..I pick the car up tomorrow....So this will be interesting.
