A number of folks have commentrd on/asked about the curve tool. Years ago, a buddy got it for me as a b-day gift. This Eastwood product looks to be the same thing. May be available cheaper elsewhere but for those interested, there you go!

Seems like I keep posting the same shots, doesn't it? But there really are differences as I keep making incremental changes.
I'm liking the ways the angles play. Everyone seems to be getting along.

And pretty quickly, it's back to the fiddly stuff. First attempt at one of the upper filler piece templates. I'm still noodling on the details of the design for this area.

Your engine and exhaust look so good thru the openings in the firewall. Maybe you should find some heat resistant transparent material to make windows.

Chris, you are a bad influence... I ended up getting me a bead roller (manual for now), so inspired by your build! Of course mine will be nowhere close to having the same amount of detail or craftsmanship (IMG:style_emoticons/default/smile.gif)

Ha! Says the guy with the CNC...
Mike, you’re going to love the bead roller and believe me, you’ll find all sorts of things to do with it.

Finalized the muffler assembly by adding the mounting tabs and used the mount as the fixture.
Using the tapered head bolts automatically centers the hole in the tab with the mounting boss. Neat little trick.

All mounted! I'll replace the bolts with something more appropriate.

Next, it was time to add these rings that help seal the exhaust as it enters the muffler. The only thing left is to add the tabs and springs to help hold things in place.

Chris, did you purchase the Boxster Trans mount, or build it?

Hi Stephen - It’s Renegade. I went with their LS and Boxster 6-speed kits. I’m a fan of “buy vs build, if it’s available...”
Though I did mod the front mount and added those spacers to move the whole drive train forward 1.5”.

Made a little tool / fixture to hold the spring tabs at the correct distance and angle. This is clamped to the exhaust tube and muffler then the tabs are welded on.

Then used that tool to install the tabs and complete the muffler install. Turned out pretty tidy.

Broke the warranty, would not expect anything less.

I like the tool, I would have just V banded them nice tight seal and done. What is the reasoning behind the springs? I never had much luck with them.

Stephen - It makes more sense when you see the whole install. With the muffler mounted to the trans, the whole engine/trans/exhaust is sorta one piece. There are v-bands at the junction of the headers and the exhaust tube. I actually got v-bands but decided on the spring approach to allow for a little movement, just in case.
I can always update to something else, if for some reason this doesn't work out.

Finally, something new: I got some of the parts finish coated.
The exhaust tubes and muffler mount have been ceramic coated. The shop that did it does mostly guns but is seeing more requests for exhausts.
The color is a nice titanium that has a sort of very light metal flake to it.

The parts look great and what a nice change from all the bare metal and rust! (IMG:style_emoticons/default/laugh.gif)
This thing may turn out looking pretty cool after all...
