I have a boll joint press tool, but it doesn't have adjustable arms, so I tried out Duncan's 2 jaw puller.
The bushing install was completed last week. This week I laid down a layer of insulation on the bottom of the trunk and another layer against the trunk firewall (where the ECU mounts). I noticed that was getting quite hot as well, but I guess it was never intended to have a header on the other side of it. I wrapped the pipes in the frunk too, but I haven't been back in there to see how much of a difference it makes.
Aly hooked me up with some exhaust bits, such that I can soon get a proper y-pipe made up, and I might be picking up some new mufflers soon...
