Question on exhausts
 

Assuming one were to take a b series all motor build that pushes decent numbers with a free flowing exhaust and put a stock axle back muffler. What kind of power losses might they experience.?

lol thats so gAY.. man just get an aftermarket exjh system for it and a silent muffler.. not a straight flow thru type one. for now run open header

don't go back to stock, if your current exhaust is too loud just get a silencer or try a different aftermarket exhaust which isn't as bad
