Exhaust- Headers- and HFC pair up
 

alright guys just want a little insight on which may be better in result of whp gains, yet also provides more sound than just the exhaust. I do live in CA so I do have to have the car "pass smog" every 2 years unless I keep taking it to my dad's friend haha, also no straight or test pipes cause I've already had a cop use a mirror under my car for being "loud"

I just installed my Fast Intentions cat back exhaust system with 18"resonators.


should I do one of the two ideas I have? or if you want give your own experience of what you have installed


Idea 1.
-Stillen/DC Sports/Meagan Racing Steel Headers
-ARK HFC
-FI 18" res Exhaust system

Idea 2.
-FI Long Tube Headers
-FI 18" res Exhaust system



Like I said if you guys got a better idea for gains and sound let me know

Go with the long tube headers, since you're also here in Cali HFC are still and "illegal" mod and will cause you to fail smog regardless. So you might as well just go all out

idea 2 ftw

So CA is screwed on exhaust lol.. so LTH sounds like more of a concensus. Anyone know what the whp gains look like on the Z?

FI all the way!

How about hooking me up with the FP option :)

you gotta call and ask tony for that lol

mine is actually rocking the CF mufflers currently. had to get state inspection so for visual purposes the mufflers went back on lol

FP option will be back on as soon as my lazy self decides to take the 30 min to jack it up and swap out the muffler section.

:tiphat:

Im rocking carbon fiber mufflers too haha only way to go :tup:
and so pretty much your are swapping the mufflers with straight pipes kind of like the AAM short tails with muffler delete?

yes. I have a set of axle back sections (no mufflers) that match up bend for bend with the FI axle back sections. no hacking up of tony's beautiful engineering was done. whole separate section was made so no I can go mufflers or no mufflers with taking out 6 bolts.

the hardest part of the switch is the one blot on each side that is behind the sway bar lol

Those look amazing! lol and I bet your neighbors hate you... hahaha :tup: How it should be haha

surprisingly the neighbors don't care but I have had complaints from people on my daily route to work. the crazy part is with that exhaust I've been heard from about 3-4 miles away maybe even more lol
