Andrew, can you link your Youtube channel to your ls1tech account, or at least put it in your signature? I imagine those following this build are your target demographic.
And when can you fly to Phoenix? We can put together a "cheap LSA swap for your classic muscle car" video series.

I would love to do that video series! Wish I had the time to do that in the near future :-(
Also, I just crested over 1000 subscribers, which is super cool. I am not Cletus McFarland, then again, I am not trying to be. LOL

I finally had an opportunity to make some mechanical changes. Due to life circumstances, I still do not have a garage, but the generosity of "car guys" never ceases to amaze me. I am currently in the Louisville area, and a car buddy in Jasper Indiana offered his shop and skills to make this possible (thanks @herblumpp!!!).
Since going with the shorter tires, the cruising RPM on the highway has been a little too high for my taste with the 4.33 gears. In edition to the gearing, I was getting really tired of the Detroit Locker clucking and chattering around corners. It's great at the drag strip, but given that this car lives on the street 99% of the time, a more street friendly differential was needed. A buddy of mine had a used 9" carrier sitting around so I bought it from him. It had a 3.25 gear and a clutch type differential. The gear wasn't optimal, but I decided to go with it.
We made some adjustments to the gear mesh and added a Strange aluminum Daytona pinion support and a CV pinion yoke from The Driveshaft Shop. This way I have two complete carriers that I can swap back and forth if I wanted to in the future.
Got the car up on the lift and saw this:
That's the life of a daily driver. Pulled the driveshaft...
The axles...
Then the old carrier...
Then installed the new carrier...
The 3.25 gear is a little tall. On the highway it is a little over 1700 RPM @ 75 MPH. The engine doesn't seem to complain, especially with the mild cam, but you can tell that it really wants to be closer to 2000 RPM to be happy. The gears also whine like crazy. I was expecting this, but was hoping the whine wouldn't be so loud.
The biggest improvement was the clutch style differential. This makes driving on the street a lot smoother.

The second part of the update was to install tailpipes in the exhaust system. My buddy was talking about building them from scratch, but then I saw that Flowmaster makes tailpipes for the 67-70 Cougars (PN 15807). These are 2.5" diameter, like the rest of the exhaust system, and I figured they would save a ton of time.
Having the car on the lift makes fitting the pipes a lot easier. I kept the original Hooker V304 stainless mufflers.
To make exhaust disassembly easier down the road, we added some Jegs brand v-band clamps. These were not super expensive and have an internal locking lip to keep both halves aligned. The v-bands were rotated out of the way in the final installation.
The end of the tailpipes got some turndowns and the pipes were tucked up and behind the rear valance. I also painted the tailpipes black, which makes them basically invisible when looking at the car from the rear. Even in this picture they are hard to spot...
The end result is a bit of a mixed bag. I was expecting the exhaust to get a little quieter, but that didn't happen. The exhaust note got deeper and but not quieter. I am probably getting too old, because I want it quieter, especially on the highway. I think the next addition might be a H-pipe, and if that doesn't do it, I may consider either adding two bullet style mufflers ahead of the Hooker mufflers, or going with a Super Turbo style muffler.

The H-pipe WILL smooth it out, or at least knock off a lot of the rough edges. An X-pipe might do that too, though I have no direct experience with that.

I doubt the crossover (of any type) will do much for volume. It will change the quality of the sound though --- subjective, but a HUGE step in the right direction. I'm not a fan of V8 sound sans crossover. After 11 different configurations on mine over the years, I finally realized that there simply was no aftermarket muffler that was going to be quiet enough for me. So I went OEM.....quiet with plenty of flow. Happy I did.
And --- nice work as usual Andrew!!!!

Which OEM mufflers are you using?

Would resonators help quiet or down or only help if resonance is a problem? I was planning on two in the tail pipe next to the gas tank if I’m not digging the sound/drone once I get there

I added an H pipe and went to the largest case 3" Super Turbos available, coming from Ultra Flows. The case on my Super Turbos is much larger than what you're running, which provides more room for packing. That quieted my car down a ton, to the point that I could have a normal conversation with my passengers and hear a lot more squeaks and rattles than I was aware of before. They are still noisy though - you can hear the car coming, it's just much less obnoxious. If you want a quiet car, an OE muffler and some resonators would probably be the way to go. The problem is finding a place to package them.
