Well, I finished the 3 inch downpipe today and just got back from a test drive. The results: way better throttle response, turbo lights about 200 rpm lower than before, and I lost about 175-200 egts. The hill I test everything on is a 8-8.5% grade and usually in 5th gear I can get the pyrometer to touch 1200 degrees, but this time I started at the bottom of the grade doing 55 mph and no matter what I did the egts wouldn’t go over 1050. Also by the time I hit the top of the grade, I was doing 70+ mph, could never do that in 5th before here are some pics of the build:
