JDM > UKDM Confusion!

[Boozer_Matt]

I have read alot of the posts and information and know that the JDM EK9 exhaust can be fitted to the UKDM EK4 if a JDM cat / decat pipe is used.

But my confussion lays in the collector!

How does it match up if if the UKDM manifold is 2.25" and the JDM is 2.50"???

I would fit the JDM exhaust manifold too, but I can't afford that right now and also, with the car due to be fairly low to the ground soon, I don't want the manifold to foul on the road surface / speed bumps etc...

Please help me so I can make a choice on exhaust systems! lol

why not just by an aftermarket 421 manifold with a 2.5" collector?

 

[Boozer_Matt]

Can't afford that at the moment as well.

Getting coilovers and exhaust on Monday 7th April.

Will get new manifold after that when I have a few more pennies.

ebay is your friend at least temporarily...

Yea...I have been having a scout about on there.

I am just unsure if the collectors will be an issue on EK4 manifolds (stock or aftermarket).

 

[RagingAngel]

if you're wondering if it's going to fit... going from a 2.25 outlet to a 2.5inch inlet...no, it will not. At least not properly.

You either run the EK4 header + cat-converter for the time being hooked up the EK9 b-pipe ...or... well..that's your only option for the moment

I can't use the EK4 cat as it will be too long for the EK9 B Pipe.

I think I have it sorted now anyway.

Thank you all.

When people refer jdm decat, it can mean 2 things. The length and the collector diamater.
Regarding your exhaust, i can see in the for sale section you are interested in the 5zigen.
If you decide to purchase, all you would need is jdm length decat with a collector size of 2.25'' ukdm.

Will this be what I need then babyface?

Honda Civic EK EJ Vti Adjustable De-cat / Test Pipe by: JPerformance -

 

[babyface]

an adjustable one will be fine m8. However, try Wizard performance as i think they sell theirs cheaper and its still an adjustable length.

That one in the link is out of stock!

Checked Ebay too, but couldn't see any.

Bought one from Tokyo Express instead.

Delivery Friday hopefully.

Hope it's the right thing.
