Since 1989 Billy Boat Performance Exhaust has designed, tested, and manufactured the highest quality stainless steel exhaust systems available. Originally specializing in Porsche 911 performance exhaust systems, oil coolers, and intercoolers, B&B introduced the Tri-Flo line named after its unique 3-into-1 Porsche header. Today in its state-of-the-art facility, Billy Boat continues to develop the highest performing exhaust systems for most sports cars, trucks, and SUVs. With an in-house dyno facility and R&D staff, we stay on top of current vehicle trends and deliver products that fit and perform to an unsurpassed level of standards.

Each Billy Boat Performance Exhaust system incorporates 3-generations of fabrication skill and racing talent. Every system starts with T-304 stainless steel, known throughout the industry as the highest quality material practical for after-cat exhaust applications. All exhaust tubing is mandrel bent on sophisticated CNC machinery for a precise fit and uninterrupted exhaust flow. What’s more, the use of T-304 stainless steel flanges offers high strength and complete resistance to harsh elements. All hangers, resonators, and tips are T-304 stainless steel as well.

Billy Boat Performance Exhaust mufflers are crafted in-house with years of racing and street development invested into the design. Each muffler is tuned to match its application for the best possible performance gain and sound quality combination. For strength, the muffler end-plates are radiused at the inlet and outlet preventing premature cracking. Additionally, reinforcing gussets are used when necessary.

    Billy Boat Bi-Modal Fusion Exhaust System for the Cadillac XLR What is bi-modal exhaust? The Cadillac XLR Fusion Exhaust is a bimodal exhaust system, meaning it has two passages, or modes, that the exhaust can travel through the muffler.  Each of the mufflers has two outlets, with one side having a butterfly type valve which allows the exhaust flow to be shut off, regulating which side of the muffler the flows exhaust.  One side of the muffler is the quiet side, and one side is the loud side. The quiet side is a smaller, muffled and chambered tube, while the loud side is 3" tubing straight through. How loud is the Cadillac XLR Fusion Exhaust? Through our development and customer feedback Billy Boat has shortend the muffler for the Cadillac XLR, making the loud side of the muffler louder, which results in a tone similar to the famous Bullet system.  In the closed position the Fusion tone would be slightly louder than the standard Route 66 exhaust system (good for highway cruising with minimal to no exhaust drone). What controls the valves in the Cadillac XLR Fusion Exhaust? The Fusion exhaust butterfly system is controlled by a vacuum valve, which was built and developed completely in house at B&B.  On the XLR with the NPP option, this valve is controlled by the Cadillac XLR's ECU.  The valve opens based on RPM and throttle position. The problem is the factory exhaust is very quiet, even with the valve open. Billy Boat's expertise here is getting the tone right for your Cadillac, and they think they have nailed this one.  Even in the closed position, the tone is deeper, louder, and more aggressive.  Open the valves and the Fusion's overall volume and tone increases to the point heads will turn when you drive up. Is the system 2 1/2" or 3"? On the Cadillac XLR it is 2 1/2".  Will the Cadillac XLR Fusion Exhaust bolt up to my stock H pipe or my stock headers? Each part of the Fusion Exhaust system will fit to a stock H-pipe or the stock headers. The parts can be mixed and matched (rear exhaust, x-pipe, and long tube headers). Billy Boat has combined the best of the Bullet exhaust with the best new technology to give you the Fusion System for your Cadillac XLR. The muffler tips are double walled, 4" round or 4.5" oval. The entire system comes completely polished and the result is a truly spectacular look and sound that gives this high performance sports car the look and aggressive sound which will have heads turning everywhere you go. All B&B products are precision built in rugged fixtures, completely TIG welded, and are a direct replacement for stock exhaust components and include all hardware and gaskets. No machining, no cutting and no welding means easy installation. We provide the perfect mix of performance, sound and style your Cadillac XLR. Each Billy Boat Performance Exhaust system is backed by a lifetime warranty against rust, corrosion or burn through and 2 full years against defects in materials or workmanship. This exhaust system is available with either Quad Round or Quad Oval exhaust tips. Tips are available with your choice of polished Stainless Steel tips--which are finished to a gorgeous mirror like shine--and new Black Satin Ceramic Coated Exhaust tips--for a more unique and aggressive modified appearance.
