Is the abarth catalytic converter different to the standard sporting one? There is one very close to me on ebay and it seems a better way rather than a de-cat pipe?
Abarth GP, GP T-Jet, all T-Jet Bravos, MiTo (120 version) Same part. SS version uses different part mostly because the turbo is different design completely. There is no performance difference worth talking about of the A500 and other MiTo models either.
