Hey 70valiant, my camo'd 85 d100 is now a super six. Had it on the road and already feel a big improvement.

Next I gotta get her to the muffler shop to do away with that 1 7/8" pipe. I have everything from the cat back at 2 1/2" with a turnout just before the rear tire. But it looks like there isn't enough room between the manifold bolts for 2 1/2" so I'll go with 2 1/4"

I still have to tweek a few things engine wise. I now have a few extra vacuum lines left over. There are less ports on this BBD carb. I doesn't seem to affect the engine so far.

Any opinions? Should I rip them out or get some splitters to hook them up to the carb?

Yep, 2.25" pipe is the biggest you can run on a stock exh manifold.

Great work - keep it up!

What to do with them depends on what they are (where the other ends of these "extra" lines are hooked up).

I have 2.5", but I cheat...
