Got my swap done a couple of months ago.
I took a chance with not having but a few miles on it to take it on a 1K mile trip
for Ruckus at the end of October.
It ran great except I had to replace the radiator fan and I had some sort of problem with fuel delivery for just a few miles.
It`s been running great ever since.
I`m just going to replace the exhaust system as I`m not happy with it.

Looks Great! Every time i see one of these swaps, it reminds me of how badly I want one...Then I remember I need to finish the body and interior work before I rip anything else apart.

Very nice job but I wonder why the PCV valve location has a long tube over it. Typically the 3800SC swaps have a very short exhaust system w no CAT and they can be loud.. If you are not happy with the exhaust sound because of the drone, try a Spintech crossflow muffler. Its not exactly quiet but it has the lowest tone of any of the mufflers that we've tried. I would advise not using the Flotech Afterburner crossflow. That muffler is very loud. ------------------

That tube is fake.
I closed off the port that was on the exhaust manifold and just stuck that tube on so it looks like it
might do something for inspection. 
Not needed as they didn`t even open the decklid when they inspected it.
The muffler on it is a spintek.
It`s the exhaust system that was on my 86 GT but I don`t know if the fire that it was in damaged it or what
but it doesn`t sound the same.
Plus I had to bend the left side outlet down because the system doesn`t fit on my coupe as it did on my GT.

Got my new exhaust in. Excuse my crappy welds. Stainless steel is probably not the best thing to learn on. Especially
flux core. The ones on the flex piece and the muffler are pretty good but I didn`t do them. An exhaust guy did.

After driving with the new exhaust I don`t mind the regular driving but it drones quite a bit on the highway.
This is a 3800 swap and I was thinking of trying one of those stainless cone baffles in the downpipe of the
exhaust right after the flange on the exhaust manifold.
I don`t have much of a choice considering it has the dual outlets that aren`t very deep to allow a baffle to go in there.
Appreciation of any options anyone knows of.
Thanks
