I've got a DC 4-2-1 installed with a 2 1/4 collector. Car doesn't seem much more faster, but it makes my car a lot louder.

 

got a dc jdm 4-1, along with my 2.5 inch cat, 2.5inch piping, and muffler, i gained a peak 12ish whp.

 

jdm dc TIR here too

 

5zigen jdm extended length so i have to run a test pipe, but it rips

 

Greddy Stainless Steel 4-2-1

 

<FONT COLOR="royalblue">I have a 4-2-1 Ceramic DC Header. I have notice a performance gain on low end, but on High end it can't breathe. I suggest you get a JDM 4-1 DC Header. Less Performance on Low end ( better than Stock ) but great performance on High end. Combine that with a Good Exhaust System and you easily add 15-18 Whp. Also get Stainless Steel! The ceramic one starts looking like shyt after a while! </FONT>

 

Last time I checked you could only run 1 header on your car at a time.

OE Exhaust Manifold for now. lol
Currently debating about SMSP or HyTECH.

 

DC JDM 4-1, Carsound Cat, Stock ITR Exhaust....haven't had it dynoed, but after I installed the DC, I could actually feel Vtec crossover. So, thumbs up for the DC on the butt dyno...

 

Its header! An inline four cylinder engine only needs one header.

I was waiting for that one

For the $ I would probabaly get a jdm itr header, Oem, Bigger collector, Slightly more expensive than a stainless Dc header.
Back in 99 I had a 4-2-1 Dc header on my gsr, it was okay, biggest difference noticed was the wieght.

Oh and two answer your question 4-2-1 provides more midrange power, and 4-1 provides more top end.

Use the search button there is tons of info on this site.

 

i have the oem jdm 4-1.

I'd just do the smart thing and save your $$$ for the high quality headers.(sms, hytech, etc..)
Thats if you're going all motor.

I dropped in cams at the same time as the header.. so i cannot accurately gauge the gains

 

TODA

 

im about to buy a megan racing jdm 4-1, $270.

<FONT COLOR="royalblue"> I guess nobody has checked out the Dyno Graph for header?
