Optimize your 2023-2025 Harley Touring M8 CVO exhaust system with the Billet Cat 2:1 Exhaust featuring a Big Bore Baffle. This expertly designed component enhances exhaust flow and sound quality, providing a deeper, more aggressive tone while maintaining performance efficiency. Crafted for a precise fit and durability, it’s an essential upgrade for riders seeking superior control over their bike’s exhaust characteristics.

Features:

  • Purpose-Built for 2023–2025 Harley CVO Models: Specifically designed to fit and perform flawlessly on modern CVO Touring platforms with M8 engines.
  • Engineered for Power: Optimized to increase low-end torque and horsepower, giving you the performance boost you can feel from the moment you twist the throttle.
  • 2:1 Stepped Header System: Enhances exhaust flow and scavenging to improve throttle response and overall rideability.
  • Complete System Package: Comes with heat shields, exhaust gaskets, bolt kit, and baffle—everything you need for a proper upgrade.
  • Sensor Ready: Equipped with 18mm O2 bungs and 12mm adapters, making it compatible with both O2 sensor types.
  • Built for Enthusiasts: Whether you’re cruising or pushing limits, this system delivers the signature D&D power and tone trusted by riders everywhere.

D&D Exhaust Baffle Choices:

This D&D Exhaust system comes with the choice of two different baffles: Vortex Wrapped Baffle or the new Big Bore Baffle:
  • The 2 1/2" core Vortex Wrapped Baffle works best on stock displacements up to 114"
  • The Big Bore Baffle works best on the bigger displacements on stage 4 114" and up.

D&D's Big Bore Baffle Details:

Our Chief Engineer has seen significant increases in mid to high range power on modified engines from stage 4 HD 114 and 117 to aftermarket 124 and up with matching cam and proper tune. The baffle is an all metal perforated 2 1/2 core ( aka big bore baffle) and will be really loud. Since we are a performance-based company, we always give our recommendations based on getting you the best performance, however if you’re willing to sacrifice some performance, you can go with this loud baffle option for the M8 Billet Cat. We do sell this baffle as a replacement so if you already have the M8 Billet cat you can purchase a replacement baffle. However, removing our baffles can be quite difficult, you might consider purchasing the muffler housing with the baffle. The Billet Cat is an end cap design if you damage the end of the muffler you will not be able to attach the end cap when finished. If you decide to change the baffle, the motorcycle will need to be re-tuned.

Notes:
  • Will NOT fit with the Harley Cool Flow Fan.
  • Bluing and Discoloration are caused by improper tuning and will not be covered under Warranty.
  • D&D Performance Exhaust Systems are designed for closed course racing applications.
  • Not for use on pollution controlled vehicles.
