I bought a 2007 Road King Classic last year, had 7k miles. It was mostly stock except for these slip-ones. I’ve inspected every inch of these things off the bike and can’t find a single identifying mark of any kind. I pulled out the baffle and nothing there either. The pipe OD is 4” and the baffle is 2.5” OD (louvered section). The pipes condition appears to mirror the age of the bike so I would guess they are circa 2007 or shortly thereafter. They sound good, not quiet but not too loud either. I’ve since added a hi flow air intake and an FP3 tuner which have improved the performance a lot. Just now starting to tinker with the exhaust. Just added the Fullsac true dual conversion kit. Sounds good, will be taking it for a spin shortly to see if any loss of low end torque is noticeable.










Anyone have any idea what these may be. I thought they might be V&H slash cut of some sort but I would have expected some markings from V&H.

 

V&H would be a good guess!
Or a Chinese/Ebay knock-off!

 

I would guess Ebay Knock off , no numbers stamped on them .

 

Rush Big Louies, slash down style

 

The little piece going across at the end of the baffle is to help pull them out and a dead giveaway they are Rush. So is no print on them anywhere. Got 'em myself. One of the best slip ons there is for both sound and performance. The deep sound wont be beat by any exhaust system out there, they diffuse very well and don't push back anywhere when using them with cams that have a lot of overlap. I'd put them up against any exhaust out there performance wise too. There was a time dealerships were putting them on everything. Too bad they didnt stick with what works.

 

Thanks very much for the responses. I do like the sound a lot and with the air intake and tuner performance is much improved.

 

Identifying the mountings can sometimes tell you a lot about the mufflers. Most times, makers like V&H and Rush will provide their own, distinct muffler supports. Take a look at another similar bike and what their supports look like. This may help you decipher if the supports are oem, or some other brand, which will help you get closer to an answer.
