233025 Aluminum End Cap for 4 Megaphone Series

This SuperTrapp closed end cap is engineered for the 4-inch Megaphone series exhaust, providing a clean, finished look to the muffler assembly. Constructed from polished stainless steel, it is built to withstand the high temperatures and vibrations typical of Harley-Davidson V-twin engines. By sealing the end of the muffler, this cap forces exhaust pulses through the side-exit gaps of the internal disc stack, allowing riders to fine-tune backpressure and sound by adding or removing discs. As a genuine SuperTrapp replacement part, it ensures the structural integrity of the exhaust system is maintained while offering the classic aesthetic associated with the brand’s performance heritage.
