RE: DA 50 Muffler Options?
For that Yak I used the KS rear exhaust can and the KS 25mm drop flex header and it all installed like a glove. Mine came in at 18lbs and flew very well.
I'm on my second one using the new 3w55i on a 3W header and the same canister and all I can saw is WOW and I'm still at 18lbs
