Soo I decided to spend some cash befor income tax.... I bought a 2.5"DP offroad from ZZP..

Since my Monte is a 05 The Rear o2 is pritty much Pointless..Would it be ok if I just Tied the o2 sensor ontop of the heat sheild?? Would that be fine?? It would'nt make my car run anydiffernt with it out, and 420 code.. (just put a plug in dp).

Keeping stock muffers for now What should I do with resonator? (Delete / Keep?) I dont hear a sound differnce on youtube at all....

I will be buying a pcm and 3.5 pully Hopefully this spring and thats when ill ask for the 420 code to be deleted...

 

if your getting the pcm make sure the rear o2 bank code is removed. other than that you should be ok. i have an 05 as well. runnin a magnaflow high-flow cat and an slp exhaust. havent thrown a code yet but the pcm is a great idea. just waiting for the weather to break here to put it in

 

I wasnt sure if I wanted a HiFlow or offroad but sicne people say with Hiflow will mostlikly throw a code. soo I just went with offroad, not cat to worrie about...

I wanna know what you think about the pcm upgrade too once you get the chance to put it in...

 

ill be sure to let ya know
