Vance and Hynes 2/1 slip on muffler for HD
Purchased for my 2014 FXDL Harley Davidson low rider . Could not be more pleased .Perfect fit . Extremely well manufactured , heavy materials , not cheap , quick 45 minute installation . Bike now sounds like a Harley , fairly loud but not obnoxious. Best unexpected news was it helped to smooth
out the normal Dyna vibration issues . Cut it by 2/3 rds for sure ! Great Great item here at a super price . More HP , substantially less vibration and a great Harley sound !!! Well packaged and immediate delivery , thanks Dennis Kirk !

Vance & Hines 2 into one slash muffler
IVE RODE A SHOELHEAD FOR 32 YEARS AND FINALLY DECIDED IF I WAS EVER GOING TO GET A NEW BIKE IT WAS NOW , I WENT TO THE H-D SHOP LAYED DOWN 7K AND RODE EVERY BIKE THERE BUT THE SPORTSTERS ECT !! THE SWITCHBACK WAS ALL SOME AND I DIDNT PLAN ON DOING ANYTHIING TO IT BUT MY OLD 74'' BIKE SOUNDED BETER THAN A 103 CU IN ENGINE . SO THE SEARCH STARTED. FOR THR MONEY AND REPUTATION I BOUGHT THE V-H 2TO 1 AND IT WOKE THE 103 UP LIKE A DIFFRENT BIKE NOT DEFENING BUT A DEEP PIPE SOUND LIKE NO OTHER . I DID NOT WANT A PIPE THAT WAS DEFENING BUT ONE WHERE FOLKS KNEW YOU WAS CLOSE AND WOULD WAKE UP MY 103IN ENGINE . NOT QUIET BY NO MEANS BUT NO HEAD ACHES EITHER PLUS EXTRA PONEYS THAT NO DOUGHT CAME ALIVE . IM ONE HAPPY CAT ON MY NEW SLED AND THE V-H AFTER I PUT IT ON WAS LIKE RIDING HOME FROM THE SHOP THE DAY I BOUGHT IT . RAISEN PIE FOR THE ENGINER.

do I have to put on a fuel module for this muffler?
keith g on Dec 2, 2016
BEST ANSWER: No more needed from stock. Ive had this on my switchback for a little over a year. This summer I removed the baffles for a while but decided I liked it better with them in.
I bought the Vance and Hines slip on but unfortunately the sound is still muffled because of the factory headers, I would like to know if you have just the headers for the slip on without the converter for the 2016 FLD?
Ronda L on May 25, 2017
BEST ANSWER: Everything but the muffler is Stock. Sounds a lot better than stock muffler. My 07 1200 sporty I traded in had short shots so my low rider sounded pussified with factory exhaust. Was almost depressing. Plan on getting full exhaust, air cleaner and fuel pak eventually anyway.
