Im looking to get a header for my 04 STi but cant decide on what to get. I want to keep my boxer sound so unequal length preferably. So if you guys can tell me what header you think would be the best for the most top end gain would be great. Thanks a lot!

 

stock ported and wrapped. All else will crack....

here joel this is the guy u got the bov from

 

Which ones have you had or seen crack?

 

Pm blinguskahn for more info. I have not had experience personally but he has. He will be able to give you the header low down. But a lot of AM ones leak, and then crack. Even the expensive ones.

 

where do i go to get ported around south bay and how much$

 

Where else other than GST Motorsports in Hayward.

www.gstmotorsports.com

 

You can also do a core trade in + $ for having your stock ones ported, polished, and coated by Crucial Racing / Method 4

 

Yeah I don't know if GST is actually doing the work their or getting it from Crucial. But they will point you in the right direction.

 

x2 for Crucial. I'd suggest the injen crossover pipe as well as my stocke decided it was going to rip open under full boost. BWAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA!!!!

 

the borla i had was good quality

 

the invidia I have is good too, haven't cracked...I've seen the borla ones cracked though =X

 

yeah man just port ur stock and don't buy the gruppe-s headers they suck!

 

I guess I got lucky with the gruppes header. with a sti top mount and the header on a retune, I gained 27 wtq on those two mods alone...

 

Damn 27whp with gruppe-s headers.. I need to get me a set
