Hello,

The power difference between the R1 and RS exhausts should be about the same. It comes down to the sound you want. The RS will be very quiet, while the R1 will have a bit more sound but is still mild.

The R1000 should yield more power overall since it's a single 80mm design. If you want loud, this is the way to go.

Hope this helps!
