Need to get some advice on headers. They will be going on a GSR motor. I have heard different opinions on 4-1, or 4-2-1 headers. Can someone give me sound advice? Dont wanna spend more that 400 on a setup here. Throw some brands and setups out there. Thanks in advance

 

I assume you already have an intake or an exhaust?...

I've heard 4-1 headers work well on a GSR

4-1 have more high-end power while 4-2-1 have more mid-range power depending on your setup...

DC Sports for me

 

in a previous honda tuning or turbo magazine.. well one of them, anyways..

they dyno'd 4 DC headers. 4-2-1 1 piece 2 inch collector, 4-1 2 inch collector, JDM 4-1 2.5 inch collector, and 4-2-1 2 piece header 2 inch collector all on a stock GSR motor.

The 4-2-1 1 piece was the best performer with i think was 7-8 whp.

The rest were all around 4-5 whp.

The reason, that the JDM ITR's high C/R needs the bigger collector and piping because its pumping more air out. They were saying anything under 10.9 C/R should stick to the 2 inch collector.

But you're gonna hear a lot of different answers.. so go with what you want.

 

I'm personally running DC 4-2-1 1 piece headers. (I owned them before I read the article). I have a 92 gsr.

 

I'm personally running an old school dc 4-2-1 header (2-piece) and i love it.

 

4-2-1 1 piece is what i had in mind, now that i see factual numbers, thats what i am going to go with. thanks 92gsr.

I got offered a good deal on a
4-2-1 Greddy stainless header. DC or Greddy Which to choose?


and yes, i have AEM intake, Apex'I full catback...

one of my boys had a greddy stainless header on his civic, it seemed to be pretty awesome.

 

you get what, you pay for, i personally have a jdm dc 4-1 . no bad feedback from me.

 

i have a usdm dc 4-1 header and im KINDA thinking of trading or investing in a 4-2-1 just to see if my midrange improves

the greddy headers have the same list price as dc headers i believe...

 

i have greddy headers on my 98 gsr and they're awesome... but they turn bronze instead of blue cause the piping is kinda thick....i might change to jdm itr though for the bigger collector cause im gonna have higher compression after i finish my rebuild....

I like the bronze look better than the blue

 

yes bronze rocks, dont the greddy headers have the 2.5" collector?
