I have two IMCO SS long risers for a Bravo set-up and ONLY ONE IMCO Power Flow Manifold. These are what IMCO refers to as the "Early Style" where the water passes through the flange to the riser. NO external jumper tube. The risers were originally the short style for a Captains Call exhaust, Young Performance Marine extended them for me last fall when i removed my stock exhaust, they look just like the factory long risers. I only removed them because the other manifold sprang a leak in the water jacket. I will sell just the risers or the manifold if anyone needs a spare. I will try to get pictures up tomorrow.
