Frequently Asked Questions
Will these mufflers fit my Indian Challenger or Roadmaster?

Are they louder than stock?
Yes—but they’re not overbearing. The 1.75" baffle offers a tone that’s slightly louder than stock, while louder baffles are available if you want more sound.
Can I reuse my stock tips?
