I recently installed a set of headers from Man-A-Fre. They are nicely finished. I also chose to use their y-pipe so I didn’t have to get it to a shop to finish the project. I also installed the their fluid heat riser, even though the climate here is mostly mild.
My only criticism was the incorrect bolts to connect to the y-pipe. I had to go get some sorter, larger diameter bolts to finish the project.
