Hey all. Soon I will need to drop the auto box from my VN V6, and after the whole thing being a pain in the arse so far Ive decided to do the manual conversion early. I compared the y-pieces today out of curiosity and found that the manual pipe has no o2 sensor fitting! It also looks a tad shorter than the auto pipe. The manual y-piece came from a VN V6 also, but a series 1 where mine is a series 2 if that would make any difference? Maybe the manuals had different headers? Bizzare lol Thoughts?
