Heck yes! And between the long tube header and my granny gear... that thing pulls like a tractor!
That's a 600 v-twin Polaris (weigs about thr same as my CJ lol) and a few hundred pounds of camping gesr in the back of the jeep, plus the coolers and the trailer ain't no lightweight either, pulled it almost 3 hours from manassas, va to Romney, wv
Go with the one piece header. I have the 2 piece on mine and the 2 piece are a pain when in comes to exhaust. I went from a four speed to an automatic and had to redo the exhaust. It would have been a much easier job if I had the single header.
wasn't sure if the stock manifolds until break-in comment was a question or not. i imagine it's about having that a/f ratio just right while you break in some rings and wear smooth those cylinder walls, keep the heat down and avoid a possible lean condition until a/f is dialed in. kinda like getting that carb dialed in right real fast on a new v-twin build.[/QUOTE]==poop3000
It was more of a WTF from the factory instructions.

I had a 2 piece on mine. Sounded good, I ran dual exhaust instead of a y pipe. I had to dent the one header so the clutch linkage didnt hit it. It leaked where it mounted to the head unless you used a lot of high heat rtv sealant along with the gasket.
I went the single as mentioned, my brother went with the dual oulet on his just to be different, exhaust shop had difficult time making a good y-pipe for it, and his did leak at the collectors, not sure if the flange leaked though
maybe i had a bum set but its a common problem with aftermarket header fors all vechiles. i was even using liquid copper after i happened and started retighting the manifold nuts after it heat cycled but i had nothing but problems with the header but i like the fitment on the jeep plenty of room to work on the motor mounts and the bell housing bolts
