Yes it will fit.
Check this thread out,
It covers off a wide range of header types in comparison to stock and the HP gains associated.

Actually fitment depends on the collector size, if its a 2.5 inch collector it wont fit the stock AUDM ITR exhaust,

In order to have a system that fits properly your going to need the JDM Cat and the JDM catback system of your choice.

If you got it with a 2.25inch collector I think you wasted some hard earned cash

On the same topic, for all headers (TODA, 5zigen, Mugen) with the same 60mm (2.37") outlet - what size cats can they, or rather, SHOULD they bolt onto?

I have my 2.25" custom cat back at the moment, but my TODA headers are going in in a week. What high flow cat should I go with?

Sorry, hope I'm not stealing your thread. I figure it's on the same topic.

the headers will not fit on stock audm cat. You'll need to get a jdm cat or get an exahaust shop to make the bell shape join need to collect the headers. The if you're getting a JDM catback later on, that too won't fit the other side of your audm cat.

Go with the jdm cat, so 2.5inch. Should fit nice and snug

wont't fit with stock cat-back, ausdm b-pipe is shorter than jdm b-pipe. do everything all at once

[xtercii]

would it be a better idea to get an aftermarket high flow cat instead?
it will probably work out to be cheaper and flow better than jdm cat??

[Jomsy]

it would be best to get an exhaust shop to modify your existing cat, you would need the 2.5" flange though, be aware that alot of exhaust shops wont have the correct one so shop around first, you may need to buy a jdm cat and cut it up

alternatively keep saving for a nice catback system and jdm cat and fit the whole lot in one go, thats what i did :D

Yeah sounds pretty straight forward, but as Jomsy said many shops don't have the tools to do the bell flange. I had the same probably, so i just went for it and changed the whole lot to JDM goodness as well. Straight bolt on, it's awsome :thumbsup:

easiest way is to get a jdm 2.5" cat with flanges.

and extend the stock cat back.

Yep, thats what I did when fitting my Mugen 4-1 headders.

i got my toda header + JDM ITR caat + fujitsubo power getter catback in like 2 weeks ago. fits beautiful =pppppppp

JDM ITR cat will take a 2.33" - 2.5" collector.. but the JDM ITR cat is 'only' 2" exit diameter.. I thried to match the JDM ITR cat and my JDM Tanabe 4-2-1 header and the header's collecter was far too small for the JDM ITR cat.

[norma]

the audm cat is also longer than the jdm cat. too long for a straight bolt on of toda headers.

if you get the jdm cat, you may also need the donut...flexi-gasket thing.

This doesn't make sense. I think you meant Collector is only 2". But in that case it's not a jdm ITR header. Sounds to me like you have a JDM B16A header.

yeah , the JDM ITR cat is 2" at exit diameter .

what should I do ? cut and extend ?

[vincikwan]

damn it, i'll cancel my order on the toda header i guess. I thought all i need to do is bolt it on n maybe just slightly modify the audm cat.

To fit TODA headers, you'll need a JDM CAT, which has a 2.5' collector. Or get a 2.5' donut flange (jdmyard sells this) and get a custom cat made to mate with the catback.
