Brian,
Great idea of using the same muffler on the same car with the change being the header / WG portion.
I like /prefer the idea of comparing the euro HE's but many may still think the B&B's are the best in class.
I still hope it will be possible that the boost curve can be monitored by the dyno against TQ & HP for comparison. Many have this capacity.
This is a better place to see any differences in the WG taper profiles, header efficiency, boost onset points, and full target boost achievement points.
Further, the turbo chosen may be important to help display what I suspect will be a large advantage of the 993HE's with its increased wast-gate capacity.
With a stock 930 or K27-7200 this dose not seem to be and issue.
As you know, the small turbine quick spool K29's and HF's are thought by some to be susceptible to over-boost. The 993's should allow for a higher initial boost setting and more stable boost management through out the operating range.
Keep up the good work.
