WHP over stock headers, Tone , Is it loud, LOL just loooking for some feed back

 

few months you'll have your answer my install date is Oct12 for the headers and HFC
here is how it will break out.
1.before dyno with my current setup on uprev
2.install of new Z1 headers with Z1 HFC and uprev tune.
3.Final dyno with headers HFC and new ECUTEK tune..
ill be posting a new thread with answer's anyone should have before they get installed
but this should be what most people are looking for and should answer what kinda numbers those make

 

This will be right up my alley as I have their cats and plenum also. If you get 20 WHP I'm getting them

 

from what i gather over at the 370z site should be good for anywhere between 10-15whp but like you i'm shooting for 20...lol
hoping to be in the high 330 range on the dyno..
Im going to take a wild guess and say ill be right around 343whp and probably 275tq after ECUTEK tune

 

found this thread for you dont know if you have ever seen it but this guy is running Z1 headers Z1 HFC and Ark exhaust
