Catback system (6-2-1 design)

This very unique KSP exhaust system features a 6-2-1 layout merging both exhaust banks ad the muffler inlets then splitting them up again,

What that does is give a very smooth linear sound paired with the KSP exhaust manifolds it makes for a good high-revving exhaust system.

A plus point of this KSP catback is that isn't extremely loud, a few peculiarities these exhausts work best with NA2 swaybars, often you'll need to be good attention to the rear bumper clearance.
