I know the real power adders are longtubes and ORY. but with my truck at a 5/8 drop and plans to one day go lower i dont think i will be fitting longtubes on the truck.

Wondering if these would be worth the buy? I doubt ill see any major gains but wondered if anyone else had any input? Also will they sound any diff that stock manifolds?
