hi guys
thinking of getting a header, but i dont know which one..
i have borla cat-back.

help out guys!!!!!

thanks a lot!!!!

 

borla headers have shown if im not mistaken the least gains

 

if you can go PM some venders and get the Diameter, Length, Variation in runners, material that its made of, and what type of power your looking for (low, mid range, or top end) i'd be glad to help you..

 

really for the cost of the headers and installation,its really not worth the gains.there are plenty of other mods which would net you the same or more.factory manifolds on these cars are not that bad.

 

I like my topspeed. good quality. or Strup. both are good brands

 

Agreed. You get better gains with a full exhaust. A guy had his at the dyno and installed and dynoed. He gained nada from headers. And he had Alpha Works.

 

Thats weird. 17RWHP gain on 20"s

yeah i'm surprised, i've seen a few dyno's for strups/alphawerks that are on the order for 15hp/20ft lb torque but on stock engines

 

Well if you look at the dyno, why did his car dyno so damn low stock? Something isn't right.

 

crawford or nismo.........search for more opinions and info

 

Way overpriced IMHO!

 

Two things: 1) Different types of dynos yield way different numbers, that is why you should always compare on the same dyno with the same conditions. 2) The added unsprung weight of the 20's and tires kills power. I have the same problem.

 

Thank you Ttank. You definitely can't compare the gains tehn between dynos because he might not have gained at all.

 

Sorry, but your humble opinion is dead wrong. Nismo, Crawford and the Nismo copy, BRM, are the only headers with a true collector. And, Crawford is the only header with equal length 22" Long tubes. My Crawfords were by far, the best "Go Fast" Mod that I have done. Installation was a major pain, but truly worth it. I'm just sorry I waited two years before I did it.

i dont think i would pay over 1k for Nismo headers. topspeed is supposed to be good, and the ones i have, ichiba, a japanese brand has given me good gains from what i can feel. car sounds great too, and the welds are really nice as well. 1k for headers? no way
