the factory manifolds are known to crack , They've also been known to warp and break the ears off the head. You'll see some reduction of egt's and some increase in spool up.
Your HX-40 and HX-35 should be flanged the same so nothing to worry about there!

HTT, ATS, BD and a few others offer the basicly the same manifold!
It may be wise to upgrade before your current manifold cracks or warps enough to damage the head!

If I can be of any assistance please feel free to give me a call!
Thanks
Lucas
