BBR – D3 Full Exhaust System (Yamaha)

The BBR D3 Full Exhaust System is built for riders who want real performance out of their Yamaha pit bike or play bike. Using an aircraft-grade stainless steel header and mid-pipe, the system is tuned specifically for each Yamaha model to improve throttle response, boost power, and cut weight. The signature D-profile muffler is lightweight, slim, and shaped to give you maximum tire clearance while still offering plenty of internal volume for consistent packing life.

This is a complete system—header, mid-pipe, and muffler—with a USDA-approved spark arrestor already installed so you’re trail-legal right out of the box. Carbon fiber touches on the heat shield and end cap keep the look clean and the weight low. Whether you’re hitting backyard tracks, local mini-moto races, or just riding for fun, the D3 delivers smooth, usable power and a noticeable improvement over stock.

Why We Like It

It’s one of the few pit bike exhausts that feels truly high-end—lightweight, great fitment, clean welds, and real gains you can feel off the bottom and through the mid. The carbon accents and D-shaped can give it a factory look that stands out.

Why It’ll Work for You

If you want better power, less weight, and a cleaner tone from your Yamaha, this system makes an immediate difference. The tuning gives stronger pull across the rev range, the spark arrestor keeps you legal on public land, and the optional Cancel Core insert lets you quiet things down for backyard riding or neighborhoods. It’s straightforward to install and built to last.
