Have Stillen cold induction. Next step the new ceramic headers. Anyone running the headers on the stock exhaust and if so, any improvement? How about sound changes?

 

next step is to add HFC, that's what I have been
trying add. adding exahaust and intake make huge improvement.
I'm impress with the exhuast note.

 

HFCs a little deeper than stock but not much louder.

On the G35C HFCs + headers = loud... not sure about the G37 but I would imagine similar results.

 

I'm trying to decide to go with Stillen HFC or Berk HFC, any suggestion?

 

Man... what do people have against fast intentions ^ i would take stillen out and have the question be berk of FI

 

Terrible ask yourself the same question??? What do you have against STILLEN???? HUH!!!!!

 

hahaha... FI has pretty good exhuast note but haven't seen any
HP/TQ increase result on real dyno.... Stillen proved 5~6HP/5 TQ increased
on my dyno... do you have anything to prove... no offense I like both
Mod but would prefer better...

 

i got a 08 in graphite grey and i put the stillen long tube intake and cat back exaust an i love it def notice a difference get a sick sound too

 

I'm going to add Stillen HFC's this Monday. I'll post up how it feels with the Stillen exhaust and intake when its all done. It wont be dyno'd though.

 

the intakes are just loosing power guys... TRUST me

 

^+1

 

I like my Stillen exhaust... but If I were hear another one or change.. I would do a comparision and show the differences...

 

^ +1... Check the dyno... https://www.myg37.com/forums/attachm...5&d=1206985940 And that's with Stillen Intake and Exhaust...

 

yuppp

 

the most bang for your buck for power that I have seen is in the HFCs.

An aftermarket exahust is otherwise great for sound and helps to complete the exhaust system- especially since Infiniti didn't quite get the exhaust note as sweet as I thought it was on the G35C and 350Z. All of the aftermarket exhausts mods hae made the exhaust note much better than stock. Whereas on the previous generation I preferred the stock exhaust note over aftermarket.
