(Pic 8) ï¼ŠThe middle pipe flair can be removed by cutting the attaching welds for use with big bore and racing engines. However fuelling adjustment will be required. (Pic 5) ï¼ŠThere is possibility for the middle flair to come off, due to the spot welding. This will not affect any aspect of the performance.
