Overview

The Two Brothers Racing 2-into-1 exhaust system is a performance upgrade designed to deliver maximum torque. Constructed from 100% stainless steel, it features race-inspired headers and a spring-retained collector for increased torque. The exhaust system includes O2 bungs to accommodate both stock and 18mm sensors, stepping up from 1 3/4" to 1 7/8" tubing before entering a 4" diameter megaphone muffler with a welded-on reverse cone.
Show original supplier description
The Two Brothers Racing Comp-S Gen II 2-into-1 exhaust system is engineered to maximize torque output for your motorcycle. Built with 100% stainless steel construction, this exhaust system boasts race-inspired headers that are lighter than competitive offerings, ensuring durability and weather resistance. From the engine, the exhaust gases flow through 1 3/4" stainless steel tubing, which is equipped with O2 bungs to seamlessly integrate with both stock and 18mm sensors. The tubing then increases to 1 7/8" before reaching the spring-retained collector, designed to enhance torque. The gases finally exit through a 4" diameter megaphone muffler, featuring a classic style with a welded-on reverse cone for a distinctive sound. This Generation II exhaust system is specifically designed for 2018-2024 Harley Davidson Softail models, including Fat Boy, Breakout, and FXDR. It's important to note that on 2021-up UK, EU, and international models, Harley introduced additional O2 sensors at the end of the mufflers. These sensors will require elimination using a Vance & Hines FP4 Fuelpak (Part # 66043) and blanking plugs (Part # 744444), or by consulting your local HD dealership.
