Beginning the winter project planning. I’m starting with the exhaust since Pypes has some nice GP buys this month. Plus these are the basic designs, so other systems (torque tech, custom/cobbled together) would be similar in nature. This is for the 77.
Exhaust choices:
Option 1:
Pypes SGF11 - 2.5” "Rear-Exit" System w/ X-pipe
• 16 gauge, mandrel-bent, 409 stainless steel pipe
• Street or Race-Pro mufflers
• Factory fit tailpipes, cad plated clamps and stainless hangers.
Option 1a:
Same as above with
this crazy x-pipe, simply for the cool factor, of course. All the cool kids have cutouts.

And look at those flames LOL
Option 2:
Pypes Crossflow setup

• True 'straight thru' flow path. There is absolutely no loss of flow thru the
muffler.
• Driveshaft tunnel X crossover kit for maximum ground clearance even on lowered vehicles.
I plan on using this one for the 67, so worst case scenario is I could take it out of the 77 and put it in the 67 and do something else in the 77. Appears to be same kit, although I have to confirm that.....
The added ground clearance is very enticing. Just looking for thoughts. The temporary turn downs have to go. LOL
