Tuning 4-2-1 Supersprint manifold

[deafmazter]

Hello,

Does anyone here have a 4-2-1 manifold on their punto hgt? Do you notice any difference and is it worth it? Supersprint says that the catalyst has to go for the extra 6hp power gain. In my eyes 6hp more fore al those expensive stuff is nothing...

yeah with cat absolutely worthless. Decat and the whole exhaust line will gave a gain of 6hp

We will see, I have 2.5" catback exhaust already. 6hp is not that bad, almost 5% gain. Plan is to change cams as well and fit supercharger eventually
