i just took out my DC header and put on my 5zigen header today with my test pipe. gotdamn! my top end pulls harder than it ever has. normal driving seems to have some spunk too. Car is a little louder than it was due to the test pipe.

DC headers suck! dont buy them. i was a believer in them until now! the size difference between the headers is very noticable.

BTW, i was mistaken on the collector size of the 5zigen. its actually 2.25. i dont have any pics but will get some up soon. Just wanted to let you all know.

 

 

It's 2.25? Hm...interesting.

 

yea.. dc headers does suck... i remember putting mine in and it felt like my stock manifold..

 

They weren't DC JDM 4-1's, right?

 

price was about 370 something out the door. my DC and stock cat were such a bottleneck! my car breathes!!

 

calling yoshi - is this the same 5zigen header you have?

is this the same header vtecvoodoo said he has a while back? thanks

 

Was your DC a USDM or JDM? How's the quality of the 5zigen in comparison to the DC?

 

the welds on the 5zigen look SUPERB! i actually had a crack in my DC, which i discovered today pulling it out. i dont think it was leaking tho since it didnt have any black **** around the crack. there is a difinate size difference between the both. i wish i took pictures!

 

So you did the test pipe and the header at the same time but comparing that to DC and stock cat? Hmm .... not so much.

 

yea the 5zigen header is tight. A friend has had one for around 3-4yrs now and he loves it and probally will never get rid of it.

 

whats the size of the collector ?

 

2.25 is what he said.

 

didnt see that , thanks B2

 

Np

 

damn. working that post count, eh?

 

So you are comparing a USDM DC header (2" collector) with a stock cat versus this new header (2.25" collector) and a test pipe?

 

he needs to get a crown

 

yes i am

my friend and i had identical setups DC header, 5zigen exhaust. his 2 door, my sedan. he has a high flow cat, and i didnt. when we would race, we ran identical times. he would jsut beat me by literally an inch.( i can just see some quoting F&F here) his car does not move like mine does now. if we were to race today i'd destroy him. peeps tell me the test pipe doesnt make that much of a difference. the only reason i put it on was because the flange on it was the right size for the header.

 

Test pipes make a world of difference compared to the stock cat.

Test pipes and high flow cats...that's where the differences end.

 

If the 5Zigen is an JDM header it should have a 2.5" (65 mm) flange!!!! I assume......

He was using his DC with the stock cat, so it must be an USDM DC.

let's dyno!

 

These headers??

 

It could also be this one:
