Some more insider information, this time from Doug Innes, former crew member for Jerry Titus and the T/G team.
"Jon, I was on Camaro site and 1st time I'd seen Mid-Ohio T/A photos. Thanks for bringing them to the forefront. In one photo your caption mentions Jerry T's long tail pipes. This was a remnant of quite a test program Jerry had going. He built a set of 180 degree headers for the gutless Pontiac and they were a nightmare to install but had a great sound to them. Nothing sounds as neat as a 180 degree exhaust.(incidentally in the early nineties a lot of Nascar teams and short track teams tried 180 Deg exhausts but they faded in popularity) We tested them at Willow Springs and Jerry didn't find any on-track power improvement with them so they got scrapped. What remained was the long tail pipe system exiting under the rear bumper. The theory was that a car sucking up behind you was going to overheat 'cause the competitor's radiator would be so close to Jerry's exhaust. The installation of these pipes was also cumbersome.
In truth I think Jerry turned a failure into a triumph as he loved agitating SCCA tech inspectors and he succeeded in getting them banned after that race. Gosh they did look nice while they lasted!"
Many thanks to Doug for sharing this with us.
