Anyone have any experience with the new exhaust manifolds that Year one sells. Looking to buy some just wondering about the quality.
Thanks.

yes , I got a set about  2006 /7  , the casting had/ has a poorly ground seam along the top  , also the high temp paint was not all that good, started rusting pretty quick, that never really bothered me. heat riser worked perfect !  also has a Y1 cast on the inside which can be seen on driver side , again no bother to me ,  apart from what I mentioned  good product no leaks cracks & they have been on & off a few times since I  first put them on .  one thing I did notice on passenger side was , the new TTI 3 inch exhaust i had fitted , the passenger side head pipe was really close to the trans cross member cut out , i mean really close , less than a 1/4" clearance ,  i easily got round this by using a old exhaust flange  enlarged to 3 inch & used it as a spacer to give the required clearance , now maybe the TTI system was at fault  or i was being too picky at clearance
