Go Dynomax Super or Summit Turbo mufflers. I love the Hooker Aerochamber mufflers with shorties and X pipe under my 88 CSC. Under my less padded interior in my 70S, droning and loud. Here is the Aerochamber X pipe setup on my 88.
LOL That sounds sweet ! Must sound great opening it up on the highway. I dunno if I wanna go there yet. But I like the Xpipe idea .. and shorties still have a chance. Shortie's separate downpipes will be easier to line up with my cross member humps.

It is more subtle wth the 260 and it's peanut cam but still sounds good. I have never heard a better sounding exhaust on a car, is loud enough inside, loud outside and an ungodly howl.

Back half is a Hooker cat back system, cut off the Y replaced with a compact X pipe. Custom down pipes with 3" collectors for 1 5/8" primary ceramic coated Sanderson
shorties, nearly as compact manifolds with half the weight.Tail pipes exit behind the wheels, all 2.5".20190412_074559.jpg

Was the compact x pipe sitting right under the existing crossmember passenger hump? Interesting.

Reworked the plug gaps today.
Also on the heads, Decades ago, the EGR lines at each port had been terminated about an inch out, and folded over to keep them from leaking. I plugged them a better way as I serviced each cylinders' plug today. At cylinder #5, the extracted EGR nut and flange were wet with what looked like oil or carbon-tainted fuel residue. (black ) So I did a comp test with the EGR replugged and the cylinder was at 80 psi. Random tests around a few other cyls were 100 or over. Didn't do them all. I'm not losing oil or water. No water in my oil. No smoke since dialing in the carb and timing. Not too concerned. Exhaust valve ?

The car pulls to the right. I could do a "hillbilly alignment" . But usually if I properly just replace the bad component, it goes right back in line. So I like to check that first. But I can't find the play. This looks like it's just simply out. My tires are all new, so I might just bring it to the shop to align.

I clean everywhere I work. Since I was under there checking the steering linkage. I cleaned up the rack, front crossmember, and oil pan. The car got the "Rusty Jones" dealer undercoat option in 82. This would give the frame impressive longevity. However, the product would eventually degrade. Dirt sticks to it, and it all hardened into this cake I am scraping off everywhere. It's like Pompeii under there. Then there's the 38 years of oil and grease all over the place.

Found out I had some leftover 10 year old Metallic Jade Green Duplicolor Paint Shop the other day. So I loaded my little 6oz. gun and gave the two small grey primer areas on the body a quick shot. Fresh paint.. but still less noticeable than the grey blotches on a dark green car. The base coat revealed I need a little glazing yet. But I can deal with that when the time comes.

Nice, good job on the undercoat when almost new. Slightly mismatched paint is better than primer, been there. Yes, the X pipe tucks under the single hump. The lowest spot for pipes is to give the oil filter clearance. Minor contact on big bumps but my car has soft springs and sits fairly low.
