Exhaust down pipe.

Post by **GreenyUK** » Tue Jan 28, 2014 12:22 pm

Hey up.
I've just has my car mot'd which it pasted

but with a kind advisory of down pipe needs looking at lol.

So basically my car is uk model with the jdm engine, at the moment I believe the exhaust setup is ukdm, the cat measures 350mm which I believe is uk?

I can get hold of a jdm decat pipe which measures aprox 270mm from looking at a picture.

So what I need to know since I know need a down pipe is what to get if I wanted to fit the de at also.

I've read a thread on here about the different lengths etc but still I'm none the wiser as so many people seem to have different opinions

I also have at home a cat back mongoose system which came off a jdm car.

So help would be great

Ps the actual manifold is a Megan racing item however the down pipe section just looked standard.

Hopefully someone with more knowledge on 4th gen exhaust will comment. On 97-98 5th gens the difference in exhaust between UK & JDM is in the length of the CAT and midsection. If you are not changing the midsection don't change the decat. I hope that it is the same for 4th gens.

Right ok see, I've heard it's the down pipe and cat that's the difference with sizes lol

It might well be on a 4th. I am not up to speed on 4th gen exhausts.

Why not just get a new flexi section welded in and a decat while they are at it?

Well I can get hold of jdm down pipe and jdm cat now, as I already a cat back system at home that came off a jdm car, I'm hoping that it should all just fit

IMO if you already have the JDM cat-back in the shed then it makes sense to get the matching JDM downpipe and decat. You'll side step any potential fitment issues when mixing up exhausts.

I have a JDM decat in the shed if you are interested?

Yeah that's true. Feel abit stupid now really

Wonder why I started this
