🔥 Patriot Exhaust H7000 1-1/4" Mild Steel U-Bend Exhaust Pipe: Superior Performance and Quality Review

Just what I needed to build my Predator 670cc. Perfect for the stock exhaust after I cut the muffler off. The outer diameter is 1.25 inches and the inner diameter is 1.15 inches. Hope that helps.

Nice narrow corner. The inner burr was flush with the tube when shipped due to reuse. It's nice. The mandrel is bent with good internal diameter retention throughout the bend. Small creases on the inside bend at the beginning of a bend, but not restrictive.

Used to modify the exhaust of the 22hp Predator 670 engine. and back. The inside diameter at the bend was .110 inches, .005 less than at the ends, much sturdier than the Predator exhaust. Worked well for my application and would buy again if needed.

99% of the big, heavy standard exhausts for the Predator 670 last about half a second before blowing up almost everything. Purchase these U-bend tubes, cut them right down the middle of the bend, and weld them to a flat steel plate to finish off the new manifold. Was the weld bad? Don't worry, it's ten bucks, try again. Repeat until satisfied. Some high temp black spray paint and congratulations, you just created your own aftermarket product. :)
