225 head pipe

I have a friend in Minnesota with an exhaust bending machine. I am sure we could make a 2 1/4" headpipe that will bolt up to your slant 6 manifold. I may even have a couple slanty exhaust systems to copy the bends off from.

Just takes someone with the "Wants" to do it to get it done.

318s run 2" off the head pipes into 2.5" exhaust tubing out to the back, and that's single exhaust.

Great performance for street driven, not running 6000 plus rpm.

I have a couple of TTI 2.5" head pipes. They're not the full length, but they stop about right under the driver's floor. Plenty to hook an exhaust to. I'd suspect for a truck, you'd need to cut the flange off and add some for more height. But I don't know.
Thanks guys! I just didn't know if slant folks had a "go to" source or not. I can have one made here but thought I'd see if there was a supplier that supported the slants. IF there was, when I do projects like this, I like to give a shout out to their company on the install video and help them and other slant owners. Looks like an opportunity for someone if they had a pipe bender and welder......
