Message better than stock manifolds. The center cylinder runner and rear cylinder runner is the most difficult to optimize the flow of gases on with the log-style design. Looking at how the center runner meets with the log shows a perpendicular path between the two where the gases will collide head-on into the log after exiting the center runner. The rear runner/collector area has the same issue as well by the looks of the pics.

Dont mean to sound cynical about them - I can definately appreciate the work involved in making mold patterns and hats off to them on their progress, but I was expecting something a bit more impressive on the performance design front.

I have spent a good bit of time porting out a set of stock manifolds and know where the thin areas of the casting are at that prohibit you from really gouging them out without having material added to the outside of the piece. It appears that these patterns will address those areas quite well and allow for a more optimized core runner, but the path of the gases out of the center runner into the log look scary turbulent.

Do you know if this is the final pattern for the parts? Thanks for the update!
