170cv NI.BA Racing Downpipe

[Alfatan]

Ciao Alfa fans,

Sorry for the English, I don't speak Italian:
I'm a Alfa Romeo Giulietta multiair driver from the Netherlands. After remapping my car at Savali tuning (biggest Alfa tuner in the Netherlands) i'm now looking for a downpipe. I came across this downpipe from NI.BA Racing: Scheda tecnica
I have some questions about it:

1. Does anybody has any experience with NI.BA Racing?
2. What is the quality compared to the downpipe from Ragazzon?
3. What are your experciences with a catless downpipe on the Giulietta anyway?

Saluti,
Thomas

Hi, in my opinion ragazzon downpipe is way better for some reasons:
1) the curve after the turbocharger is more regular
2) the diameter in the first part is bigger, and after the curve it is reduced to perfectly fit the rest of the original exhaust.

Ragazzon costs more but in this case it's worth the difference

Hi Dave,

Thanks for you reply. I will then go for the Ragazzon. My "feeling" about the Ragazzon already was better, so this confirms my feelings. Thanks!

Excellent result! Did you use a lambda emulator?
