Frequently Asked Questions
Do these slip-ons require fuel or ignition tuning?

Will these fit my 2010+ Softail?
No — this part number is specific to 1991-2009 Softail models. 2010-and-newer Softails use a different chassis and require different mufflers.
What's included in the box?
The pair of Twin Slash slip-on mufflers with mounting hardware. You reuse the stock header pipes.
Are they street legal?
Slip-on exhaust legality varies by state and local noise ordinances. Check your local regulations before purchase.

Best Sounding and Looking 2 into 1 slip-on IMO
Replaced my S&S Grand National slip-on with this bad boy. I never was satisfied with the S&S sound....kept hearing YouTubes on the Vance and Hines slash cut ....it sounded like a Harley should to my ears, so I bought it and am very happy that I did! It not only sounds cool it looks cool. Oh and if you own a 2026 Heritage, you do not need the saddlebag mount that the order system say you do...save yourself the hassle of returning an unused part.

Sounds amazing
This thing makes a massive difference. It's a great inexpensive option to get that sound. I got the chrome, and it lines up and matches perfectly. Looks like it could be stock. Certainly doesn't sound stock. It's not monstrous by any mines. You're not going to get pulled over or annoy your neighbors, but it sure has a deep aggressive sound to it.

Looks and Sounds Great
Great looking and sounding muffler. I only gave it four stars because there is clearance issue with the rear axle on my 2026 Heritage. I had to put a shim between the muffler and the frame mount to ensure the muffler wouldn't contact the axle when the suspension was fully unloaded. I think this is something that V&H should have addressed when designing the muffler. It was a simple fix, but shouldn't have been necessary.
