someone had a similar knocking noise that was vacum line under the manifold/connected to bypass valve...research this forum and see if it pops up, he even posted a couple of videos so we could hear the sound. to be honest, your knock sounds pretty bad. how that came about from changing the exhaust is pretty questionable, that is why i asked if you were there during the install.
today i found out that one of the piston is gone ((

engine couldn't handle that supercharge stage 2 unfortunately need to buy new pistons ... i ll go with forged pistons
