on me! well, i was driving in an unfamiliar area (known for its "bad luck") and ran over a parking curb... oh wells, I guess its that time for the SMSP i always wanted...

 

Thats not too bad. I've seen worse. Definitely a good excuse to upgrade though

 

damn vincent always have to mess your stuff up before you replace it huh?

 

it happens , time for an upgrade

 

Vincent, where have you been hiding?

 

Man, that sucks...and yes, the unfamiliar area is very unlucky.
Hope you had some fun bein a ricer for a couple hours though.

 

At least it's only a header. Good excuse for an upgrade.

that's true, i've seen worse header damage

 

No worries, my JDM DC is worse than that....

 

Damn that sucks, good thing there is no other damage. My mom did the same thing to her R and smashed the dc header on there.

 

whats the diff between a jdm dc header and just a dc 4-1 header? say for a b18b or b18c1?

arent the jdm dc header's 4-1? is it stil the same size bolt flange?

 

JDM DC 4-1 = 2.5" collector

Any other DC header is worthless. Makes no useable power.

 

well the reason i ask is cause i have a dc 4-1 header on my b18b.

dont all b-series have 2.5" collectors?

and if mine isnt a jdm then its not making anypower? that boggles me.

 

No, your header isn't making any real power. Most b-series are 2" or 2.25" collector.... only the good ones are 2.5"

 

if mine isnt a jdm 4-1 header then its just a standard dc sports 4-1 header? whats the difference between my header and the jdm header? and why would mine not make anypower?

 

Because there's a huge difference in the design, as well as the larger collector is a huge improvement. You won't see a good header, like smsp, dtr, header-tech, anr, etc... using a 2.25" or 2" collector, because it sucks.

 

so basicly ur sayin all 2-2.25 collector headers suck no matter what they are?

 

Yes.

 

so with that said, how could i put a 2.5 header collector on my engine? and if its not possible due to the fact that the b18b doesnt have a 2.5 inch collector, then no header on the market will provide gains?

 

The JDM DC will work, but you have to get 2.5" exhaust and a 2.5" cat....

 

so if i had a dc 4-1 header and a tanabe racing medalion ehxaust, im not getting any gains outta these?


this doesnt make sense to me. and how can u tell a jdm dc 4-1 header from a dc 4-1 header? just the 2.5 collector?

 

with the usdm dc 4-1 and the tanabe rm, you're probably making maybe 5-8 useable hp....

The JDM 4-1 doesn't have the carb plate on the header, thats another way to tell. Take a look at mine....

 

Measure the diameter of the primaries on your header. Some of the DC USDM models are actually 1-3/4" just like the DC JDM. The USDM DC GSR header is also 1-3/4" tubes but the 2" USDM collector. All you need to do with those are cut the collector off and add a taper with a 2-1/2" outlet.

 

jisecup...the search button is your friend... dont ***** out someone else's thread

you will not be making 5-8 useable horsepowers from your usdm dc header and racing medallion if you are already driving a type R
...more like 3-5 hps

 

I don't think he drives an R, but you are correct.
