The 3800's do drone bad at cruise. My fbird was almost unbareable once I put mid length headers and a medium cam on it.
I have full 3" to a pypes race pro 3" in and out, and a vibrant resonator 3" in out right before the exhaust. It's good at cruise and a bit throaty in boost. The vibrant resonator was just the smallest clean looking affordable one i found, but there are a bunch of different options.

Turbines quiet exhaust quite a bit. It's best if you use more than one.....
D!CKS!!! 
Made a plug for the tailpipe that fell off, and it's actually somewhat reasonable. I'll have to make the commute a couple of times to see if I can live with it.

I realized the power door locks aren't working since the speakers went in. Once all the fuses checked good, I set to check power at the relay. Then, I noticed that the housing is metal and probably needed to be grounded. I zipped a screw to the firewall, and viola! The locks work again.
Burnout in the garage!
A few more bugs to work out, and I'm good!👍

Ok, now, I'm becoming borderline suicidal. Drove it in to work today, and as it was idling in the driveway, I though something sounded funny. I get in and the oil pressure is down about 20psi from where it was. I made the 45 mile commute (mostly highway), and at the last traffic light before work, that funny noise was worse (sounds like multiple rods) and the oil pressure was down even further. I wouldn't call it dangerously low, but coupled with the noise, I am definitely not a happy camper. I'll try an oil change and bump it up to 10w-30, and see what happens.
Wow it just doesn't end. I hope it works out ok
I feel your pain. I had the engine out of my Malibu three times this winter. First was to replace a pistons I broke last summer. Figured I would do rings at the same time because it's the right thing to do. File all the rings, put it back together and it idles perfect, has great oil pressure but seizes anything above idle. I screwed with it for a few days, jacked the engine up in the car far enough to get the oil pan off! Took all eight rod caps off and two mains in a futile attempt to find the issue. Put it back together after I didn't find anything wrong. Started up, oil pressure was at 45psi cold idle, went to 20psi within about a minute. Oil pressure would drop to zero at idle after it warmed up, lifters would start tonrattle, give it some throttle and it would build about 8psi which is enough to shut up the lifters. Pulled the engine again and stripped it down. It ate three out of the five cam bearings....FML!!!! Swapped the whole rotating assembly over to another block I had hanging around. Threw the big cam I had in the garbage and put it back together. I drove it for around five miles and the oil pressure dropped off in this engine too. I changed the oil and filter and it went back up. Has been good for a couple hundred miles now. Hope it keeps running this time!!. I ran down a hellcat Challenger on the freeway with 5 people in mine last Saturday.
A drop in oil pressure is not good. I wiped the mains on my 403, it registered as 7 psi and was just down on power. Fresh crank and bearings, correct? What about the rods, resized? Does the 3800 still have the same crappy aluminum oil pump cover? Most of the bottom end issues I saw in shops were the pre 3800 motors. Sorry to hear this, I used to have a 45 minute commute as well, our 04 Corolla, bought in 05 with 13,000 km was a life saver, reliable as hell and 50 mpg. It did eat tires despite two alignments at two different shops, not uneven wear, just wear out. Even the nice Goodyear tires got 60,000 km and we're completely wasted, rated for 100,000 km. Just a thought....
