Nice but I would of made them the same length extra lil bend back and larger arc would of worked good still nicer than stock I’m building a alloy exhaust for my mower soon I’ve got a few mowers to build
Looks pretty sweet especially seeing them on a vanguard rather than a intek garbage can engine! BUT I understand they're a dime a dozen for a intek anywhere you turn your head. From the looks of the metal coloring you used stainless on the tubing?? I'm in the middle of building a ground up fully custom turbocharged vanguard for a golf cart of all thing's...... Had my fun with 2 strokes in it but nothing beats the sound of a nasty V twin with a cam!!! Wish you lots of luck and fun on the race tractor. I was building race tractors yrs ago until the arthritis in my back neck and tail bone couldn't withstand the pain anymore. So settled for something with some suspension system in it lol. Nice build the tractor looks sweet!
Did you work out a tuned length, or just go longer than the stock Briggs headers? I've built one for an ultralight and it flies well, but the 38" the online calculators say is ideal is a little heavy, would be nice to cut it down to 18" or so Cheers Kev
