custom exhaust for 2011 30i

hey fellow members,
i would like to ask if i would lose power from custom exhausts for the 30i. i was told this won't happen with the 35i cause of turbos or something. But for the N/A 30i, would i experience loss of power?

Also, what price should i be expecting? SYdney aus

"[B]

Back pressure caused by the exhaust system (consisting of the exhaust manifold, catalytic converter, muffler and connecting pipes) of an automotive four-stroke engine has a negative effect on engine efficiency resulting in a decrease of power output that must be compensated by increasing fuel consumption."


So the answer is NO you wont loose any power
