Help picking HFC's Gen III

[Roddy]

Hey guys,

I need to add a pair of HFC's to my 06 Viper. Right now the ones I am looking at are the Random Technology HFC's from Viper Parts Rack ($599 per pair):

Would these be a better option or easier to install ?($299 per pair):

Right now my car has cat deletes and a corsa cat back. I'd like something that just simply bolts up. Any advice would be really appreciated. I'm adding these and a custom tune to decrease the EXTREME smell of exhaust fumes.
