i am having my local dealer put on the GMS1 on in a few days (i want the upgraded hardware for future possibilities of trifecta/hp tune tune) I have a K&N SRI that will be put on right away. i am looking into either the ZZP top Charge pipe or the Injen. IMO the ZZP looks way better, but there arent any curves in the Injen, would that be better performance wise? its not money wise an issue, just looking for my best bolt on bang for the buck sort of deal. Im thinking of the MPx inter cooler, and then the MPx downpipe. love the sound of those, im just unsure to go with catted or catless. i love the catted w/ muffler delete, and i fear if i go catless itd be to loud. i dont want to be obnoxious, could i just go catless and keep stock exhaust? just looking for optimal power gains with simple bolt ons.

Also to go HPtune or Trifecta? all prices aside and brand"loving" aside, what would be the absolute best bolt on combination for the power (keeping the mpx exhaust cuz i love that tone )

thanks guys!

 

I feel that HPTunes are better

 

your intake
injen charge pipes and upgraded couplers from mpx
zzp intercooler
zzp catless downpipe or badmab downpipe.
new clutch
then hp tune it with torque management off and 24psi max, then you will be set.
must get clutch before an hp tune though, or you will regret it

i have a catted downpipe with muffler delete stock exhaust and it sounds awesome, but the catless with a muffler is the best way to go for power.

 

for the mean time while i save for my trifecta or hp ( depending on what i do )... will my K &N SRI, MPx Catted DP 3'' catback (decided on that, wouldn't be able to handle the raspy sound for too long) and Injen CP combo with my GMS1 throw a CEL?

 

It may throw a code with the K&N without a Tune.
I'd go Trifecta, although I'm biased. Trifecta has written over 2,200 SS/TC Tune/Retune files.

 

as long as the filter is facing up properly, then no codes will show up..and hp tuners will give you more options and power, but if nobody is near to do it for you, then trifecta will be more conveniant...gl
