Nice heavy duty steel! Just what I needed after burning a cheap Amazon header in half. The flange is so thick that I did have to get longer exhaust bolts! I got the brace with it and highly recommend it too!

Bought for my son's go kart which has a Honda GX390. It fits perfectly, looks slick, and makes it purr like a kitten. Would highly recommend for custom go kart build.

Should come with shorter exhaust studs. I was already committed to altering this-I needed most of the bends, but couldn’t do straight center dump. Took 15° of bend out of the last curve and cut stub, welded to increase OD to fit carbon muffler. While welding I added spacers to exhaust flange to be able to use OEM studs.

Hemi 420cc header pipe.
Perfect fit, looks great, fast shipping, all gaskets included. I gave it 4 stars because I wish it came with studs for the exhaust as the stock studs are to long and I had to go buy some washers to fill the gap between the threaded part and the shaft of the studs. I guess they fixed the issue with it being to close to the valve cover because mine is about 2in. a way from it. Overall it's a great upgrade for the engine.
