I was thinking about putting some extractors on my AE101 4AFE engine as well. Found some decent looking ones for $220 in a shop. Only downside is that I am borderline automotive illiterate so any advice or thoughts would be appreciated. Is it worth it? Will I notice the difference? Should I upgrade to 2" piping as well? I have the 4" cannon on there at the moment so that might be the only bit that won't need upgrading. As said, any advice or opinions are appreciated :laff:
