yeah...honestly idc as much...im selling my fujitas for stillen 3rd gen...and im getting stillen headers

3rd Gen is sound great! but i heard the installation was PITA and hopefully no water issue! and since you already has HFC install if you plan to put HEADER it will be freaking loud.I guess.BTW Stillen HEADER doesn't look good as well.
They done a bad welding job i ever seen. Search on G37.com you'll see

Ya don't get stillen headers.
Herd a lot of negative things about them. Bad welds, leaks, and such.

Your numbers are very low for a car with hfc, intake and exhaust.

My stock about a year ago was about ~265+whp (cant remember it exactly) and 230ish torque i believe so with all those add ons something is wrong i think...

I was thinking the same thing.

And looking through your pics again, I swear I can see through the mesh on the lower bumpers.

^Thats cuz he changed the fake mesh with real mesh lmao

so what headers should i get???

I would wait until something better than stillen comes out.
You can get IMPULs though
But you would have to fabricate them to fit the sedans. They aren't even made for the sedan yet. Only the G37
I had to get mine fabricated to fit, but the fvckers messed up a weld, which is being fixed right now.

But wait till something else comes out, which im sure it will.

yeah...im so depressed now seeing my dyno numbers...makes me wanna kick my car right in the *****...is it just me or does anybody else get times when they are so depressed and pissed at there car??

Ya i do, but then i get over it once its better lol
I think it's cuz of your exhaust setup. You have the HKS mufflers, stillen Y pipe and stillen hfc...u still have the stock piping from the Y pipe to the mufflers. You need a full cat-back exhaust system bro.

yeah..btw would u consider selling ur headers or ecu...ill pay good money...and yeah...i need to sell all that crap under and inside my car and start all over....get fast intentions exhaust, hfc, impul header, technosquare, injen cai...then ill be satisfied

I don't want to sell my headers unless they give me problems again cuz im getting them fixed now. I love my reflash lol
I'll be getting fast intentions hfc and exhaust soon
I hope i'll be in the 320+whp and 250+tq area.

But what do u want to sell inside your car?

my stillen exhaust w/ hks mufflers, fujita intake, stillen hfcs, black ravspec roof spoiler, custom painted trex grille, messed up ravspec front lip,...and anything else u can think of
