This 2-into-1 exhaust system is designed for large displacement, high output engines. Similar to the Fat Cat system, but has increased capacity for larger engines. The Boarzilla is an excellent choice for engines with performance modifications and plus 25% or larger displacement. The muffler includes a 2-1/2” core perforated baffle. Includes full-length header heat shields to ensure great looks over the long haul.

D&D’s philosophy is to trust their own R&D program, developing their product line to reflect what they learn during their countless hours of testing on the D&D dyno. But they didn’t stop after they made big power, they also built systems that are engineered to fit and look great! Inspect a D&D pipe, and you’ll find true craftsmanship—from the hand-ported inlets and collectors, hand-fit heat shields with machined and welded steel clamp brackets, heavy-duty mounting supports and flawless finishes, you’ll know you made the right choice for your Harley®.

All models are available in brilliant chrome or high-temperature black powder coat finish. Includes full-length header heat shields to ensure great looks over the long haul.

APPLICATION NOTES
• These Boarzilla exhaust systems will not fit FLSTC Heritage® Softail® models with factory saddlebags installed due to the upswept muffler design.
