system vs backbox

[JG_VTR]

obviously an exhaust system is better, but what are the real differences?

[hesslevtr]

you mean cat back
manifold back
or including manifold

[PinguFurio]

im confused.. what are the differences?
cos i got a de-cat full exhaust system . .

[hesslevtr]

back box obviolsley is just a back box

cat back is a better flowing middle section and back box

manifold back is above plus de cat

everything is uprated manifold plus the above

hope thats easy to understand
