It has a HSC engine. Does the cone create a swirl in the air which the High Swirl Combustion engine needs? Or is it a silencer that I can remove to gain HP and fuel economy? I know these were lemons but it has no rust, was always garaged and has 130K KILOMETERS on it. See my sketch of it below… Thanks for your help.
