3" Exhaust Install w/ DSE Quadra Link

[seattle67]

Hello All -- I'm almost done with the assembly of my 67 pro touring camaro, but have run into some snags installing a 3" exhaust system. I'm running a narrowed Ford 9", DSE quadra link rear suspension, narrowed DSE fuel tank and mini tubs.

I've seen some pics on the DSE site showing what appears to be 2.5" tubing installed, but even that is ridiculously tight. I REALLY want to avoid doing turn-downs at the rear axle, but pushing the 3" pipe over the axle and panhard bar, then around the fuel tank and out the back seems next to impossible. If anyone has tips or pictures demonstrating success in this area, I would greatly appreciate the help!
