Sorry, the 70S. The Sanderson shorties with custom bent 2.5" down pipes into a compact 2.5" X pipe all under the passenger hump then the back half of a Hooker 2.5" cat back exhaust is going back on the 88. The poor 260 needs all the help it can get, this system really made a difference past 3000 RPM and was very slightly stronger down low and sounded beyond great. It was droning and just didn't sound the same on the 70S. I need the mini starter I have for 88 due to the down pipe routing. I have two full size starters I want to use. My 88 has squat for ground clearance compared to my 70S, I still got occasional scrapes on my 88 but have since put on 1" taller front tires. I seriously have about 6" of ground clearance with the 70S. I want cheap exhaust, I finally want to get my 403 block to the machine shop and finally assemble the 424 stroker short block this year, so the most affordable is best, not a $1000 exhaust. Has anyone tried the ball and socket adapter, will it work with regular style collectors? Otherwise I will go Copper or Aluminum collector gaskets and may still have Cooper manifold gasets I would coat with RTV.
