Wanted, Slip-on pipe for R1200GSA K25 and low/lowered rider saddle.

[sparro]

The bike I recently bought has the Remus headers and midsection.  However it came with the standard heavy zorst.
Looking for a Remus, Akra, Leo Vince or similar slip on that i can just bolt on.

Then I'm also looking for a lowered or low version of the rider saddle for the bike.

Thanks
