they don't have any holes in them but I think that two may be doubles. Like Cyl #1, #2, #3 and another #3. but I can't tell. I can pack and ship them. Let me know. Thanks, Daniel
i have the same set i'm trying to sell super cheap HM 405. One of the pipes has the end cut off
Also an aftermarket 4 into 2 set that only has a sticker on them saying made in japan
