dont know too much about PORC products..i know a lot of people love theyre SYE..i have one myself also. but i already really like my rustys kit. id go rustys, but thats because i like theyre stuff...but nothing against PORC
Rusty's coils are my favorite out there by far. I ran the 3" ones for years and recently went up to the 4.5" ones for my fullwidth build...absolutely no complaints there.
