Looks fantastic 
How much restriction will that baffle create with you pumping pressure through the system?
I think its not as bad as many people think. I modified the pipe with a 40mm perforated tube straight through so its resonable quiet while still offering enough flow.
On my other turbo bike I first had a 60mm straight through pipe and later a 35mm end pipe and I honestly could not tell the difference except there was no TuBa droning in my ears anymore. 😅
If theres a bit more back pressure, the wastegate will simply close a bit more to compensate. Thats the beauty of the system.
