Hi, I am new here.

I own a 2014 390 Duke which has been run for 44k kms. Recently, I adjusted the valves and de-carbonised the engine. Now I wish to install a free flow exhaust on it. I was using Daytona on my old 2008 R15 which was a full exhaust system but on the Duke, I wish to attach Leo Vince Cobra (universal exhaust). I have the bent pipe with me, which used to remove the cat. Anyone using full exhaust system here?

Also, can anyone tell me how much extra torque I can get from it?
