hi guys .. am new here ..

i have G35 2003 COUPE/auto

air-intake ((k&n)) , spacer 5/16 , Underdrive Crank Pulley , buddyclub consider

soo what next ???


am planing to buy a test pipe and headers but in my country in summer the
temp is 50 c' ((soooooo hot )) so which headers you advise me to buy ??

the (((stainless steel))) or the (((Ceramic Header ))) and which one is powerfull and what kind ????


any advise ???

 

It doesn't mean u'll get more power with one of the two... It's quality... Stainless cost more cuz it's stainless steel... Stainless steel will hold up longer...

 

soo what do you advise me ?

 

stainless...

 

does the stainless ok with the hot weather ???

 

I would buy either Crawford Z or DC sports headers and get them Jet Hot black coated to keep the under hood temps down a little.

 

dc headers model NHS 4201s,

 

dc sport headers or even a good copy. i had stainless steel copies of the dc sport header from some guy in texas. he threw in test pipes too, paid 500 dollars total including shipping. just as good as any other headers. sounded great. jethot coating not necessary.

 

... ditto. some fujitsubo y-pipe clone (gruppe-s) w/dr.gas reducer, dc clones (pro-1 or topspeed), and some hi-flow cats (crawford's), and you're off. retune would be next.

 

If you get stainless, make sure you get them coated. If you're not going to coat them, then get the ceramic.

Ceramic produces less heat than the stainless. Considering you're in an extremely hot climate, I'd go ceramic.

If you have the money, stainless headers and coating them would be ideal.

 

Satinless all the way!

 

i bought the JDM headers with the tset pipe ... the car is not pulling in the
4th like befor when it was stock..... i can just reach 230 k/h



and today i changed the stock Y pipe with Nismo Y pipe .. the sound become louder but still not pulling in the 4th....

i do not know why??? ..... the test pipe is 3 insh
the Y pipe is 3 insh
the stock exhoust is 2.6 insh


so what is the problem????

 

do you have a reducer cone?

 

i will uninstall the headers and the test pipes ...

also the air-intake and everythings .... i will back to stock ....
