A) Short Ram intakes will not provide much if any gain for our trucks and would require a lot of work to get them to function properly as the location to make a short ram would put the air filter in the middle of the engine bay. A cold air intake is made for our trucks by K&N, however it is still in the engine bay, not sure how they can actually call it cold air.
B) Glasspack would have to either be welded on or you can use clamps if you do not want to pay for it to be welded.
