Just finished welding up my homemade cross over exhaust and gave it the smoke test in some static WOT runups.   Here's some info....(Lyc O320 160 HP, Sterba 69X75  prop) 

 

run # 1 with new X-over exhaust 2270 rpm ( readings are as best as I could tell on the steam gage tach) 

run # 2 with the Y pipe exhaust  2220 rpm  

run # 3 with new X-over exhaust 2280 rpm  

 

so it looks like about a 50 to 60 rpm gain on the avg on a static runup.   Now on to making some heat shields for the alternator, starter, etc where those pipes come close to...
