Mk2 golf 8v upgrade to mr3 exhaust manifold and down pipes

[Alex Mckenzie]

Hi all
Looking at freeing up the flow,
I understand you can upgrade the exhaust manifold and down pipes from a mk2 8v (RV), the question! Will the manifold and pipes need to come from a 2 litre ?.
Is the 1.6 litre the same as the 2liter

Cheers

For clarification. I've been advised changing my stock exhaust to a mk3 manifold and pipes will give better flow, thus extra hp. I've found a wrecker with one off a 1.6 mk3, I just need to confirm if the manifolds and duel down pipes are the same 1.6 & 2liter.

Any advice would be appreciated

Has to be from a 2 Litre M3 Golf.
I think you will find the 1.6 M3 is actually a 1.8, ADZ, engine.

Thanks for the info, now just have to find a 2 litre

Yep i did this to my mk2. Works even better with no cat and resonator

doing this mod

I read the gain is 5-7 hp increase, can you notice it increase or i sit just a dyno thing.

the increase is top end only ?

with less back preasure do you lose torque?

I'm considering a diffrent cam in a few month, anyother worth while mods ?

Hey mate,
did you end up upgrading your exhaust manifold to the MK3 version?

I've got the manifold waiting to go on mine but its not yet at the top of the to-do list. Interested to hear experience from others before i set out to break something that's currently working OK

The standard MK2 manifold on Aussie cars is a joke, you could block the gas flow with a 20c piece. It looks like a decent size pipe but it tapers down to a pollution legal (strangle) size.



Here's the dual pipes in my MK1.



The dual downpipe manifold from a MK3 is a great improvement. It depends on what mods you've done to the motor as to how much extra power you get but 5hp on a standard motor sounds right.

How difficult is the swap? I'm assuming and hoping not the head off like in your pictures?!?

Head doesn't need to come off but makes it much easier to get to all the bolts.
