Frequently Asked Questions
What Harley models does this fit?
This system fits Harley-Davidson Milwaukee-Eight Touring models, 2017 and newer. ⚠️ VERIFY exact years/models for this SKU against Drag. CVO models require the Bassani Floorboard Spacer Kit (part 09-0121).
What are the specs?
Hand TIG-welded stainless steel. 1-3/4" headpipes step up to 1-7/8" into the collector, feeding a 4" OD straight-can 11" muffler body with matching aluminum end cap and a removable spiral-core louvered baffle.
Is it 49-state emissions compliant?
⚠️ VERIFY per SKU. This system comes in a 49-state high-flow catalyst version AND a race-only version. Both are not legal for use in California on pollution-controlled vehicles. Confirm which version this barcode is before publishing.
Do I need a tuner?
Yes — a fuel processor/tuner is highly recommended. Popular options include the Vance & Hines FP4 or Dynojet Power Vision.
Is it hard to install?
Most Bassani systems are DIY-installable in about two hours with basic tools. Replace exhaust gaskets and torque to spec to avoid leaks.
