SP Concepts Cutback Exhaust for 2018-2026 Harley Softail

Product Description

SP Concepts Cutback 2-Into-1 Exhaust for 2018-2026 Harley M8 Softail

Give your Milwaukee-Eight Softail an aggressive performance look and deep exhaust tone with the SP Concepts Cutback 2-Into-1 Exhaust. Designed for performance-focused Harley-Davidson riders, the Cutback combines stepped stainless steel headers, a compact 4" rolled-cone muffler and a CNC-machined billet aluminum end cap for a distinctive short exhaust system that looks as good as it performs.

The Cutback uses heavy-duty .065" stainless steel headers that step from 1-3/4" to 1-7/8" and then to 2" at the collector. This stepped-header design helps maintain exhaust velocity while providing the flow needed for performance-oriented Milwaukee-Eight engines, making it a strong choice for stock motorcycles as well as bikes equipped with intake, camshaft and other engine upgrades.

A 4" rolled-cone muffler houses a 2-1/4" coiled perforated baffle designed to produce increased torque and the deep, aggressive exhaust note SP Concepts systems are known for. The compact Cutback muffler design gives the bike a clean, performance-inspired appearance while the CNC billet aluminum end cap provides a premium finishing touch.

Every Cutback system is hand TIG welded from top to bottom and uses machined stainless steel header collars for a durable, high-quality installation. The exhaust features 18mm oxygen sensor bungs and includes 12mm adapters, allowing compatibility with factory O2 sensors or applicable wideband/autotune sensors.

Choose from Stainless, Black, Polished, Black ONYX or Platinum finishes to match your build. A Low Rider ST-specific configuration is also available for the proper installation on FXLRST models.
