any companies sell packages?

OK, actually thought my r had an rsc catback on it, but out it in the air and find out it only has tips welded on lol. now im wonder if companies like unitronic, apr etc have packages? exe intake, tuning and exhaust?
I really really like the ie450t turbo kit but not the 6k tag lol.

apr sells their tune free with their downpipe right? not sure of anyone else.

nope never mind you just get a free upgrade from stage 1.
