OOTV and I are looking for a set of used 6th gen performance slip-on midpipe/mufflers to purchase, borrow, or have donated for use dyno test/tuning the prototype new VFR800 performance header. The new header thread is here: https://vfrworld.com/threads/new-5th-6th-8th-gen-performance-header-now-in-production-in-usa.56300/ A cosmetically damaged 6th gen slip-on would be great if fully functional. Any brand or model that is open flowing is fine; Two Brother Racing, Delkevic, Micron, Leo Vince, Akrapovic, Scorpion, GPR, Staintune, etc We would prefer to accept a generous donation or loan and will pick up in southern California or pay for shipping [pay for shipping both ways if the slipon is a loan], but we are willing to purchase. WE ARE NOT PICKY. Thanks for your consideration.
