TTI Exhaust on Early A's

Don't get me wrong, I think tti does a great job.....but the consistancy is a little hazy. I followed the instructions to a tee, but still had to modify things to make the headers work. The biggest hassle was moving the brake lines. My prop valve is in the stock location, and I know the headers would have hit the lines on the original drum brake setup. And yet, I gained clearance in other areas from the Doug's. But the headers work! The first run with the new 408 was a 12.08 @ 5800' altitude. Hopefully 11's soon.
