Has anyone tried the novarossi 2630 pipe with the mega zx12 dsII+?
How is the performance compared with the 2607 pipe? I run on a
short track and need low-medium power, so the 2630 with
6 fins manifold is a good choice? I know 2607 is the way to go for
all picco-based motors but is kinda hard to find.

Thanks,

well i have tried the 2630 with the medium manifold on a JL evo3. similar engine, performance was ok but i soon went back to the picco pipe.
