DC JDM header ?

[SuperTeg]

I was seriously considering getting the DC JDM header and I was just curious if any one had any experience with this header on your JR auto. I would think that it would be good for Supercharger because of it's 2.5" collector.
Anyone got any input on it as far as it being worth it? I currently hace DC 2 piece 4-2-1 and will be going to the JDM version.

It's a good header. We use them all the time with great results.

That was my first choice, but this shop said that I would need to weld the collector together. I didn't want to go through all that trouble of getting it welded.

I am going to try one on the Blackbird... as a matter of fact, it hangs on it now.

My concern is that it may be a give/take product. What you gain by having the larger collector may be offset by the losses of the LONG primary runners... Supercharged cars like really short primary tubes... thus, this is why the Kami is so popular with the JRSC crowd.
I hope that I am wrong and it makes LOTS of power.

yeah me too! I would like a better header for more boost, but I don't know if I want to mess with the Kami.

i have a question here, i just installed a DC JDM 4-1 header with a gutted hi-flow cat. I also have an apexi N1 exhaust, the thing is, after i put the header and gutted cat my exhaust has this "zinging" sound.
Is there any way that i can get rid of the "zing" sound?! I probably have to change the gutted cat to a normal one right, i lose some power that way though!
Before i put the header and gutted cat, the exhaust sounded WICKED!! A nice deep rumble, i want to get that deep sound back, hopefully not losing the gutted cat!!
ANY FEEDBACK would be greatly appreciated!

I get a buzzed sound when I warm up my car from my N1 exhaust. *shrug*
