98 Spec JDM ITR 4-1 Header, will this fit my AUDM B18C?

[JDMintegra]

planning on upgrading my exhaust to a full catback Mugen Twinloop but don't know if I need to swap out my AUDM headers with a full JDM header or buy a cat that bolts on a JDM catback system to the AUDM headers.

obviously I did consider buying a Toda or Mugen header but at the moment don't have the budget for it, so would the JDM head provide any real gains and difference in noise?

Cheers,

just buy a jdm cat

[tiah313]

if u hv the money u can get the headers too, it will give u some gain with ur catback system and is better than stock head for sure, but as u stated u gonna upgrade to toda or mugen head soon, then why bother wasting ur money buying old headers then sell it again when u got ur mugen one. so atm just get a jdm cat in order to install ur catback and then save up for toda headers =)

I was feeling kind and was going to give you some rep points until I carefully read what you advised and its not very correct.

The dude has AUDM header & JDM cat-back.

Buying a JDM cat isn't going to solve his problem, it won't fit into that combination.

He needs a custom cat.

If the set-up were to work with the JDM cat then he would need to buy the JDM header as well.
But he has said he doesn't have enough money yet.

thats why i told him just to get the cat, and save up for better headers, i didnt tell him to get headers

You didn't just tell him/her to get a "Catalytic converter"

You told the OP to specifically get a "JDM Catalytic Converter"

A JDM catalytic converter will not fit. The Op will need a Catalytic converter that is custom length/custom made because AUDM header & JDM cat back isn't just a bolt on affair.

JDM header, JDM dc2r Catalytic converter, JDM cat back is all a bolt on combination.

If there is AUDM header there it isn't bolt on.

^^^ wat this guy said

i think jdm dc2 cat will bolt onto aus dc2r header and bolt onto the mugen catback too.

Where you buying the JDM 98 spec ITR 4-1 from?

i think jdm dc2 cat will bolt onto aus dc2r header and bolt onto the mugen catback too.don't make me neg rep you.........

[tiah313]

up to you u as long as u have a reason =)
this is a public forum do whatever u like

[JDMintegra]

thanks bludger and tiah313, much appreciated comments as I was abit confused with the specs between cats, headers and exhaust. Planning to get the twinloop to cat and as you guys said a custom cat to bolt it onto my audm header :)
wish i had enough funds to get a toda :(

[JDMintegra]

planning on buying from here but deciding where to get the twinloop from, still saving for atm

[t200]

Anyone know the size of the AUDM headers that connects to the cat?

[dc2r-0636]

i believe its 2.25inch. JDM is 2.5inch

[TheSaint]

really u could probably cut., weld, chop etc to make anything fit with anything

but getting the right flange combination is a tricky business =/
