I can tell you right now that everyone hands down for power uses longtubes on the truck motors. However, space considerations obviously come into play here. I am running shorties, but am concerned with them coming very close to the frame. Block huggers are also an option. Just remember that you can use car parts too. Some of the older gen 3 vettes came with titanium exhaust IIRC. I can also check the clearance rack at summit for you if you decide on a particular type. I still think my idea of the motorcycle muffler zoomies is the best though
