My car is at a custom exhaust shop getting your exhaust fitted. These guys do a lot of high end work. You know what they said about your exhaust?
"This is by far the nicest home-built custom exhaust we have ever seen". "You sure this isn't an actual Borla exhaust"? if that isn't a compliment, I don't know what is!

Wow! That is a heck of a compliment! Honestly, I'm just happy that you are satisfied. When it's all said and done, I'd love to see a video and hear it. I have no clue how it will sound, I just hope its mellow. I yelled through that muffler and was impressed at how much sound it cut down. Clearly, it flows very well too!
Any way, Starting things off with a top shot.
When I powder coated the valve covers, I kind of forgot that I needed to add a breather. So I went online looking for a 3/4" bulkhead barb, and found that it is a common part used as a boat's bilge pump exit. So I picked one up. Bonus, It's stainless! It was a bit wide at the flange 1-3/4". So I put it in the lathe, cut it down to 1-3/8" and drilled a 1" hole in the valve cover. slipped the seal in, and passed the fitting through and secured it with the nut. This worked out well! I didn't have to disturb the powder coating by any kind of welding.
It also cleared the spark plug holes, and it appears that it will clear the brake vacuum supply, I can always adjust its exit angle.
I got my 4AN 90 swivel today too, so that allowed me to adjust the wastegate cooling lines to a much more appropriate orientation where the bend radii are much better.
I also started working on my fuel tank lines. I've always hated the hose clamped lines at the tank, so I went ahead and added a couple of push connects to the tank. This way I can use the high pressure nylon lines instead of metal lines for the fuel. Just so long as they are well protected, they will last forever, and are much easier to work with, at least once you get the ends on!
I scavenged the plastic fuel lines from a 4th gen Firebird. I welded on the little ends that I cut off of some fuel rails.
I also put the quick connects on my fuel lines going to the fuel rail. I just need to find a place to put the fuel filter, and get the lines all fitted.
That's all for today!

Its sounds crazy good!! It doesnt have that typical 3800 tractor sound. It sounds a lot like an old flat-plane crank Ferrari. Its an odd but pleasant sound. Oh yeah, no adjustments were needed to fit it. The only part that was cut and welded was the J pipe that goes from the flex joint to my downpipe. Success!

That is a great idea! I might have to start doing that as well.

It sounds NOTHING like any 3800 I've ever heard. Sounds downright exotic! Thanks for posting that!
