Lupo gti 4-2-1 or 4-1 exhaust manifold??

[Lupo_Gti_Kor]

Hi, this is only Lupo gti owner in korea. 

 

I ordered a Sprogley SM PRO intake this time.

I'd like to install an exhaust manifold soon, but I don't have any info in Korea.

Are there any differences between 4-2-1 and 4-1 manifolds?

And the 4-1 manifold is being sold in Kam Racing, but I can't find the 4-2-1. Can you tell me where they sell it?

There is an awkward part because I wrote it through a translator. Thanks for reading it.

It depends. The trade off is torque vs power. The way they work is very dependent on RPM and the resonant frequency in the pipe. So to get the best results, you need to be able to play with ignition timing and cam timing. And you can add a bigger bore exhaust and more silencing so you actually end up with more power (and/or torque), but run much quieter. Mercedes are very good at it.

You might want to read up on header and extractor flow theory... 🙄

And so cool to have a club lupo member in Korea! My guess you have a Jap import?

Yes mate! 

Koreans only like big and comfortable cars, so they didn't even think about bringing cars like Lupo from Volkswagen Korea. Polo only got diesel and it didn't sell well.

 

I hope the torque goes up to rev limit after 3000 rpm, so what type of manifold should I use? Let me know if you know the brand of the product! Thank you.

If you can play with the ignition timing and change the cam timing (both ECU work), then I'd go for 4-2-1. If you can't change the mapping, I'd keep it original.
