Yes, less than TWM's and keep in mind these are not cast. everything is machined, the throttle bodies and even the trumpets are all 100% CNC'd.
Here's another design aspect that I am proud of. The trumpets are extreemly easy to change. They actually screw into the base plate. So, different legths can easily be adapted for different applications. For example, a racer might want a shorter stack for a high-end track like Willow and a longer stack for a grunt track like Sears Point.
