I’m building a new engine for my daily-driven ciao as I want more low- and mid-end torque than my current engine (before the Athena engine I had a 43mm Olympia engine which had more low-end torque)

Current engine

– Athena (Eurocylindri) 50cc
– Polini high compression 38,4 mm head without decompression valve
– Modified carter (max intake size, extra channels for the cylinder, match ported)
– Original crank with increased intake timing
– 13/13 Dellorto with Polini filter
– Gianelli original power exhaust
– No vario

New engine

– DR Evo 43mm
– Polini high compression 43 mm head
– Modified carter (max intake size, matched to the cylinder)
– Original crank with increased intake timing
– 13/13 Dellorto with Polini filter
– No vario

Can’t decide which exhaust to use on this engine.
I want to have an “original look” so not too big or too noisy…

I’m not that happy with the Gianelli original power on my current engine, it’s suprisingly loud at high revs and I think it lacks power.
I was thinking of a Leovinci SP (cigar) but it seems almost impossible to buy anywhere?
What other good allround exhausts are there?
