Why choose these flow tubes
Designed specifically to work with BBK products, these flow tubes offer a reliable, race-tested path from the mid-pipe back to your crossover mufflers. The built-in O2 bungs mean you won’t have to add sensors later, reducing install time and potential leak points. The included collector bracket ensures a secure, stable connection, helping maintain exhaust routing under load and vibration. If you’re upgrading from stock tubing or repairing a damaged mid-pipe section, these tubes provide a clear, direct upgrade path that maintains proper scavenging and exhaust flow.
Who this is ideal for
- Performance enthusiasts upgrading to BBK long tube headers
- DIY mechanics performing mid-pipe-back exhaust repairs
- Fender-to-frame routing projects that require precise 2-3/4" tubing and reliable flange connections
- Shop technicians assembling or reconfiguring crossover muffler systems for improved flow
Use cases and installation insights
Install these tubes when you’re replacing or upgrading mid-pipe back sections and you want seamless compatibility with BBK long tube header systems. The universal fit and standardized 12-inch length make them a versatile choice for a range of vehicles. Expect a straightforward install if you’re pairing with BBK ball-and-socket collectors; you’ll benefit from the welded O2 bungs, which simplify sensor placement and sealing. If you’re fitting to a vehicle with 1-3/4 inch primary tube collectors, the flared female connection is recommended to ensure a snug, leak-free interface.
Practical tips
- Double-check your existing header primary size and collector style to confirm compatibility with BBK 1-3/4" primary tube collectors.
- Plan for trimming in tight-fit scenarios—the tubes are designed for universal fit but may require minor trimming for a perfect seal on some builds.
- Use high-quality gaskets and appropriate mounting hardware when securing flanges to maximize leak-free performance.
- Inspect the welded O2 bungs during installation to ensure sensor threads seat correctly and there are no gaps around the bung welds.
With the 2-3/4 Inch Exhaust Flow Tubes, you get a purpose-built solution that aligns with BBK’s performance philosophy: precise, durable, and ready to pair with BBK Long Tube Headers for dependable exhaust flow from the mid-pipe back. Whether you’re extending your setup, repairing damaged tubing, or upgrading to a more efficient configuration, these flow tubes provide a clear path to improved performance and reliability.
