Great product Review by jim
I installed this 606 system on my 2019 Softail Slim. The instructions were clear and all parts fit perfectly. I like this as it maintains the stock bobber look with a slightly smaller diameter cover. (Posted on 7/17/2019)

Flawed, but saved by excellent service Review by Belloc
The individual parts of this kit are well-made, but there were several snags getting it mounted due to some weird issues that would take too long to explain here. I did get it installed though, after a couple of hours of tinkering. I wrote out the problems I had in an email to DK that night, and Dwayne called me first thing the next morning, apologized for the trouble, explained various things and fixes for future kits, and promised to put several parts in the mail should it give any trouble in the future. So I guess this is as much a review of DK's service as of the kit. In any case, the kit makes a very noticeable difference in the bike's performance - there's a bump in power, and just as useful, a dramatic improvement in throttle response, all without touching the mapping or stock pipes, and without making it run lean (see DK's testing on this kit - it feels even better than their dyno tests suggest). I can't believe changing the filter made this much difference. The critical thing for me was that it doesn't make it run lean, but the only reason I did it was to get the breathers out of the intake after seeing all the oil in the stock paper filter the first time I cleaned it, and feel the improvement just cleaning that paper filter. Anyway, highly recommended. (Posted on 1/7/2019)
