By fit what do you mean? Will it physically fit? Yes. Will it bolt dierctly up to your stock system without modification? NO.

the lower heatshielf of the jdm itr header won't exactly prevent scraping, its made of the same thin metal the upper heatshield is made of. there are some companies that sell a 'skid plate' thats thicker and stronger. it fits into the same places the heatshield bolts into. heeltoeauto.com i know for sure carries one.

Re: which header to get? (Stock_LS)
Yes I could raise my car up but as it sits I am only about 1 3/4" below stock. I have been thinking about doing the skid plate thing but I'm going to sell the header. The headers warped at the flange (no idea how it did this since I followed the proper tightening sequence and even tightened it back up after it warmed up.) My next set up is going to need a custom header anyways so I will deal with the clearence issues when it gets in.

4-2-1 headers are for low end power
and 4-1 headers are for high end power.....it all depends on where you want your power to be.....also ceramic coated can crack easily i heard, so it would probably be best to go with stainless steel....
as for brand...ive heard good things about DC and Greddy.....

Comptech not only has nice low end gains but good mid range and high end. On a stock ITR the comptech peaked 1 or 2 WHP more then the JDM 4-1 with no loss to the 4-1 at high RPM's. I think other 4-2-1's are made for low end however the Comptech has shown it can do just as good at high RPM's on a bolt on vehicle. If your building a serious all motor ride go 4-1. Just bolt-ons comptech OWNZ and has no ground clearence what so ever.

Re: (maggsgsr)
Agreed. My only issue is the same issue that is involved with ECU chipping. Not all motor set ups are the same so not all headers work the same for each person. Alot of factors come into play when choosing parts for your car. What works for one person may not be the right choice for another. You can be close but for maximum power, you need to consider your engine setup and the end result you want.

the megan header is great. it's very good quality, nice welds. its actually a 2.5 inch collector. my friend has a couple at his shop, i can take a few pics if anyone wants and post them up.

My friend purchased 1 and it was missing welds. He decided to return the header and didn't even put it on the car. It does look like a kick *** header besides that.

Thats what I thought too...however, isnt that a little bit of a catch-22, how to decide which header to get?? For instance, on a GSR (which has vtec) you get most of your power at the high end after vtec engages. Granted, for the size of the engine, the compression ratio gives it pretty good torque at the low end as well, for the engine size, etc. So, where would you want the power? I mean, if you went for a 4-2-1 header, you'd improve upon an already decent stock compression ratio and torque rating. Doesnt the GSR accelerate on the low end pretty well already?
With a high end 4-1 header, you get your power once you hit vtec, am I right? So wouldnt a 4-1 header improve top speed as opposed to acceleration? Thats the catch right there though...the vtec engages and already generates power on the top end. So getting a 4-1 will just give it a higher top speed.
Which is better then? Faster acceleration or higher top speed? (I know it comes down to preference, but given the compression ratio, the prevalence of vtec, etc. what would be a better and more efficient combination?) A GSR compression ratio with 4-1 header for speed, or GSR compression and torque with a 4-2-1 header for improved torque?? It sounds to me like give the GSR's already suitable torque and compression the decision would naturally lean towards the higher top speed...Do I make sense, or am I overthinking the header issue??

Re: (MugenGSR2001)
who cares about top speed. it all depends on the design of the header. read up more on the design of the header and how it relates to your motor and what you want to do(goals, powerband ect.)

Pretty simple place to start , then deciding on what your goals are find the header which is most suited to your needs.

If I may ask, what didnt you like about it? Not enough power? Issues with fitting it properly?? Ive heard the DC sports headers (when ceramic coated) have a habit of flaking or showing wear too easily. Is this true? Im trying to decide myself which header to get (4-2-1 or 4-1) and which company to get it from. Any suggestions would be appreciated (dont mean to butt in on anybody's thread)...Ive already got an AEM CAI and a Tanabe catback exhaust for my 2001 GSR.</TD></TR></TABLE>
1st of all wut i dont like about DC are: the piping are'nt big enough like jdm itr, the way its bended its kinda like crossed to each other unlike jdm, comptech, etc..., and then the collector is so small too, and last but not the least the ceramic one i had it the weld is weak it crack, leaks air, theres a black smoke marks on the headers where it was welded on the top of it where the carb stamp thingy at... but right now i think dc made a copy like jdm, comptech, mugen, toda, but still not big enough piping and collector like jdm itr one.. correct me if im wrong.

look in the h-t classifieds...i saw this one the other day, not a bad price.
