Alright, lets see, who makes these...

What?? Nobody does? Oh, okay, guess we'll have to then!

Available in stainless steel, this pair (both included) are the same dimensions as the factory header flange, used on the SC430 for instance. If you're looking to make a set of headers that bolt up to the factory H or mid piping, this is what you'll need. Or perhaps your exhaust is rusted, and you just need replacement options.

As seen in the pictures, they match perfectly over a factory header, but still give plenty of room for improvement when it comes to flow.

We also make the flange that goes from the manifold to the head! That can be added as well.

Factory exhaust manifold not included. Why would you use one of those anyways? Ew.

Please note this is a different flange shape from the non-VVTi 1UZ, and they are not interchangeable

Full set of all 4, for one engine! Perfect for making your own header design, whether it's for long tube, pulse tuned, or to hang a pair of turbos on your V12. We have a few sets we keep in stock, an XAT exclusive! 3/8" thick stainless steel, made in the USA!

Looking to upgrade your rig with new headers? Maybe doing a UR engine swap and need to fit a custom set? Or perhaps youre looking to add a turbo or two to your Toyota 5.7 or 4.6 truck V8? In any case, we have you covered! These are 3/8" thick stainless steel.

As is typical from us, another first to market product! Price is for both, 1 pair for 1 engine!

These likely fit other UR engines as well, however we have not yet confirmed fitment. They might fit 1URFSE and 2URGSE heads, but we have not test fit on those engines yet. They are made specifically for 1URFE and 3URFE/3URFBE engines, as seen in the Tundra, Sequoia, GX460, Land Cruiser, LX570, and overseas LX460.
