Engine turn it? I've already disaster'ized it =P

I was looking at my exhaust options. Basically either half the Skylark's old exhaust or half the Firebird's old exhaust. I cut the Firebird's old exhaust in half. I thought about leaving the dual part from the X-pipe back, but opted against that. I should have enough exhaust stuff to be able to cut out and replace the remaining X-pipe piece with a good piece of mandrel bent tubing. On the right is 2.5" Skylark mandrel bent exhaust from a Summit universal kit complete with Summit brand muffler. On the left is what came with the firebird which is 2.5" regular bent exhaust with Flowmaster mufflers, I think 40 series but don't know for sure.


I should be able to make some quick back to back tests on how each sounds.

The Summit brand one bolted up.


The Flowmaster brand bolted up.



Wired up the control panel and megasquirt. It's pretty hokey but it'll get the job done. That battery is an old one out of my Skylark that I am pretty sure has a dead cell in it. I have the charger on it now and I think it'll get the job done just fine. It never up and quit on me, but would instantly drop to ~11.9 volts when the key was turned off, but would start fine the next day or even several later from 11.xx volts.




The outriggers for some anti-roll support. I won't get too crazy with revving it if things look shaky.



As the car sits right now waiting for rear gears and all the other work.
