Last but not least Chris and team put back the hot side on the car and then started where the 4" downpipe terminated at the firewall to finish the exhaust which is 4" ovalized s/s tubing and a single 4" race muffler. We were planning to put an e-cutout on there by the firewall or just past it; however there doesn't seem to be much room. The lowest part on the car is the torque arm so far.
Of course the transmission and torque arm mounts had to be notched/clearanced to clear the 4" exhaust. You can see on the frame the welds from the frame boxing kit they added to further stiffen it up.
They are making headway and the stars may finally align where it is driveable in the next few months. Going to have traction control via the Holley Dominator EFI using boost by gear/time. The ZR1 front hubs have speed sensors and then a trigger wheel/pickup will be added to the rear pinion flange. The Holley plots the acceleration of of the front wheel vs. driveshaft speed to determine if timing/fuel should be pulled. The brand new tires are now officially 2 years old... so they need to be exercised ASAP
