Seems like I'm flooding the board with different posts, to which I apologize, just have a lot to figure out and figure maybe I'll help some others in the process. Fortunately this post is more for a future state planning, so here goes...

Picked up a Dana 60 front end last night to ultimately replace my blown up 10 bolt once the 60 is rebuilt. It's geared to 3.54 and my 14 bolt is geared to 4.10. My question is which axle should be regeared? See my signature, I have a 6.5L NA, 700R4, and 305/75R16s. I'd like to find the happy medium between fuel economy and towing capability.

Then, I need to do something about my exhaust. PO put in a hacked up single 4" pipe all the way back, no muffler. This thing is LOUD. Too loud for hauling family on road trips. I'd like to quiet it down but still maintain a high flow for performance. Should I go back to dual exhaust? Maintain single exhaust? What mufflers would you recommend?

One step at a time ...
