2 system and 3 system exhaust?

[markus_74]

Hello,

Need some info as above.

Does 2 system is only front pipe and end muffler?

Does 3 system is front pipe middle exhaust and end muffler?

Does use middle exhaust give more middle torque?

And what is the main function of middle exhaust?

Should I use this or not?

Thank you
Markus

Both systems have middle and rear boxes, but are made up of either 2 or 3 sections....

3 piece has downpipes, middle box and rear box...
