I've got the Sirio version matched to my Evo4 STI in my MP9 and am very happy with this combo, awesome power and delivery, and great run time, was getting 8 mins during break-in running really rich.
"Sirio hand select and assemble the major components of the STI engines with crankshaft, case and rod individually numbered - so that you (and Sirio) know exactly what you're getting. The sleeve is handmatched to the crankcase for optimum flow characteristics, This is all part of the STI package"
Quoted from an RC magazine review of the STI Evo4

I ran a tank through my set up yesterday at my local track. After a quick re-tune, it felt really good, even on top. Today is our opening day for outdoors and will report back this evening. I don't know for sure what happened at MotoRama , but after yesterday I'm feeling much better about this pipe

Been running the Big Boy pipes for a few races now and really like them,
Ran a series race this weekend, switched back to Byron Gen 2, was getting 13:28 of run time in my Losi buggy. Noticed about 2/3's through the race day that I had got hit in the pipe, leaving a good sized ding in it. Ran it that way in the main and couldn't tell if it was affecting anything, with a ding that size it ahould have. Was still getting 13 minutes of run time in the buggy. Might do the freezer trick to try to get the ding out.

I ran one practice run, two 5 min heats and about 5 mins into a 10 min main on Sun. I had cutch issues all day, but I'm very happy now with the pipe. The engine is now coming alive on top

I ran the pipe for the second day, and when carrying my car back to the pts i noticed something rattling around, the entire inner venturi in the pipe came loose and is rattling around 
there's a small dent, more like a very small flat spot on the bottom of the pipe, but nothing that should have caused this. anyone know what trinity's warranty is like?
heres an attempt at a pic, you can see the metal inside is the part that has come loose
