1986 honda 350x head pipe needs identified Non oem

[ctk]

I am changine the exhaust on my 86 350x, that had a dg rcm on it. When I took off the head pipe I noticed it was not the same as a oem one I have. The oem one came off a 85 350x. Im not sure if there is a differance in 85/86 head pipes . I got some pics. The whiter of the two is the 1985 oem headpipe. Its also wider where it mounts on head and has the flange where it meets the spark arrestor. Is there gonna be a differance in power between the two? Could the one that is not oem be an old dg head pipe?

yes, it could be a dg. or any other that made them... i dont think much if any power will be noticed with these 2 different head pipes....
