PaceSetter Header
 

Are they any good? Are there better choices/options for a NA? I have an '86 that I am R&R'ing the 7mge. I would like to take advantage of the engine being out to upgrade the exhaust.

Well those annoying rice can cars sure use them all the time. Check this out from an earlier thread on here.

I think the OBX headers seem like a better choice. They look more balanced for the I6 firing order, but the only way would be a flow bench and few dyno runs. The only thing, the O2 sensor bung needs to be cut and welded closer to the collection pipe, that way the sensors readings are more accurate.

If I were to get the OBX header I would re-enforce the welds around the flandges and where the pipes meet, and then move the O2 bung closer.

I just purchased an stainless OBX header for the MK3. $207 new in the box.
