Exhaust flames aside, the answer is left up to the individual, lucky owners.
From a performance standpoint, we at Supersprint know that the N54 engine has a great potential for substantial gains in midrange torque and peak Hp.
The Supersprint turbo downpipes and full exhaust is the right bolt on addition for boost tuning, letting the max Hp be increased to 430 and more.
Available from Supersprint Exhausts in Italy, since 2011.
