i wanted to know if i should get nismo headers? i have injen cai and invidia exhaust. and also get a motordyne spacer.

 

IMO, i think with the price associated with those Nismo headers, you would much better off going with Strup, DC, or other companies that offer the same performace for a whole lot less.

 

well someone is selling them to me for a great price that i don't want to pass up.

 

It depends on how much if its neard the 500 range then by all means do it. But if its more than that, i would rather buy strup.

 

yea..thats how much he said. how much hp gain should that add?

 

Headers would add at the most 8-10 whp. Have you ever considered plenum spacers or performance plenums? They actually add 3-4 more whp with less than half the price of the headers the person is selling you. search for AAM, Crawford, Kinetix plenums.

 

In california if you are looking for headers, go with DC Sports... They are the only CARB approved headers for the 350z...
