Get rid of a major restriction point on your 1994-1997 7.3L Ford Powerstroke by upgrading with this two piece downpipe from Diamond Eye! The factory downpipe is flat and restrictive. The Diamond Eye 3" 2 piece downpipe for 94-97 Ford Powerstroke will increase exhaust flow, lowering exhaust gas temperatures and will give you a slight horsepower increase. These come with a flange at the bottom that bolts to your factory Catalytic converter. If you don't have a cat, simply cut the flange off.
