Exhaust systems

My 08 SD is completely stock but will likely change all that over the winter.
Specific to the exhaust, is there real benefit in using a complete system, Akrapovic, versus aftermarket cans, Akrapovic Yoshimura FMF etc, and the stock header?
I do not intend on riding at the track anymore. Just want a solid hard running bike for the street.
Of course the intake system and fuel mapping will be upgraded.

Hi mate, welcome here!
Don't want to come down on you to hard as this is a great place to be with nice people (myself not included)
This subject has been flogged to death and over so maybe a search will enlighten you.

Plenty of maps both for tuneecu and power commanders here on the forum too.
In short full system looks good but as far as I know there is not much gain on a standard model and probably a bit loss of torque.
If you do other mods a full system might help.
Ditching the original boat anchor at the rear however helps to save about 10 kgs and makes a few extra ponies too.
