I am looking into my next piece of the puzzle which is the header and I narrow down the choice to DC 4-2-1 or a JDM Type R header. Question is would the JDM TR fit on my 2001 GS teg? and if so, anyone have any estimate as to how much a 2.5 cat converter cost? What's everyone's opinion on it??

get the type R headers Calvin the dc ones are nice but the type r do much more like there better in lower end torque and if you can find a shop who does this , just have you cat removed I hthiugh you had the 5zigen exhauts diesnt that take the cat of the system???

My 5 zigen is just the Axle back kit, so the mid pipe and cat is still stock, I plan on getting all that done once I figure out which Header to get. (Even Better if I can get a bolt on Mid pipe from 5 zigen...)

what type of sound do you get from your 5Zigen? also, have you considered the DC 4-1? thanks.

I personally love the sound, not too loud, nice range, deep (not too deep). It gets loud on the highway, but so far I don't mind it.

But to be honest, I haven't REALLY Heard it from OUTSIDE the car hehehe, inside it was just righttt hehehehhe

Yea thought about the 4-1, 'cause I do have in mind a JRSC in the future (far future). Also I have another option.. GReddy 4-2-1... so 3 choices... (also I am told the ITR header might not fit. oh well no biggie, hehe.

the problem you might have with the ITR header is the bolt pattern. it may not fit perfectly, unless you drill new holes. i know the ITR intake manifold requires a different bolt pattern to be put on, say, the GS-R. just a thought.

actually, i read somewhere that the HyTech Type-R header is suppost to give something like 20hp. but i'm not going to pay the price for that - something like $1000. :eek:

hmm yea I think I will get the GReddy header, best bang for the bucks.

Anyone have any experience installing them? if so any tips? ( any url?? )

What are your plans? All motor or turbo/supercharger? I personally don't like JRSC, just cuz too many ppl have had problems with them. I'd go turbo on your car. The B18B is an awesome motor to turbo. I think it can handle up to 8-9psi on stock internals.

If you go all motor, then LS/VTEC is an option as well. You got both high end and low end power!
