BBR – D3 Full Exhaust System (Honda)

The BBR D3 Full Exhaust System is built for Honda pit bike riders who want a real upgrade in performance, sound, and durability. Using aircraft-quality stainless steel for the header and mid-pipe, each system is tuned specifically for Honda models to improve throttle response and overall power. The lightweight D-profile muffler is a big part of what makes the D3 special—it trims weight, increases packing volume, and gives you extra tire clearance when the suspension compresses or when you’re tossing the bike around.

This is a full system right out of the box: header, mid-pipe, muffler, carbon fiber components, and a USDA-approved spark arrestor so you’re legal on public trails. If you need to keep the neighbors happy, the optional Cancel Core insert brings the exhaust note down to near-stock levels and can be swapped in or out depending on where you’re riding.

Why We Like It

It’s light, well-built, and delivers smooth power without any weird dips in the curve. The carbon fiber heat shield and end cap give it a clean factory look, and the fitment is some of the best you’ll find in the pit bike world. It feels like an upgrade you notice right away.

Why It’ll Work for You

If you want stronger pull, quicker throttle response, and a lighter system that fits perfectly, this checks every box. It’s trail-legal with the included spark arrestor, it bolts on easily, and the optional Cancel Core insert gives you flexibility for backyard riding or track days. For Honda pit bikes, it’s a dependable, purpose-built system that improves the way the bike rides and feels.
