yes u can get the apr stage 2 without testpipe, thats what i did. Problem is it still feels kinda slow. so i installed the testpipe and was happy with the results except for it was really stinky. i knew testpipes are stinky but mine was BAD. so I just put HFC a couple of weeks ago and it doesnt stink anymore but lost hp for sure

 

i dont notice the smell, maybe at first but that was because my engine was burning the wd40 that was sprayed on the pipe to get the bolts off, once that was finished burning i really dont notice a smell at all, i do now have a p0420 code calling out the cat tho, so i gotta save up for apr stage 2

my question is, my cruise control doesn't work, from what i hear, it is a clutch switch that is known to fail and from what i understand, apr uses the cruise control switch to active the diff modes of the software, so with my cruise control was inop, will switching apr modes work?
