The middle section is 2.3" piping if i'm not mistaken, comes with original FGK Y-section to split into the twin mufflers. inlet for mufflers would be 2".
Selling it for RM850 negotiable. Price is slightly high as i've got included the original FGK middle piping and Y-section. If i'm not mistaken, AutoEquip is selling the mufflers only for RM600 already. Initially bought the set for my car but it doesn't really suit fitting onto a Corolla SE :(
Dei... normality, i didn't know you were looking for these la... but i'm not selling the muffler only, selling the full set including middle piping.
