Description
Khrome Werks 202665 4.5″ HP-Plus Chrome on Chrome Slip-On Mufflers for 2017-Newer M8 Touring Models
These 50-state emissions-compliant slip-on mufflers replace factory Touring mufflers when used with a catalytic converter head pipe. While Khrome Werks focused on compliance, the design still delivers strong performance, style, and sound. Dyno testing shows a 12% torque increase and a 7% horsepower gain. At the same time, the mufflers produce the signature Khrome Werks authoritative tone without harsh high-frequency noise.

Baffle Insert Descriptions
Khrome Werks 202708P Performance Insert
This insert restores torque curves without sacrificing high-end horsepower. While it slightly reduces exhaust volume, it works well for high-performance builds such as 124 and 128 big-bore engines.
Khrome Werks 202711P Ripper Insert
This 2.25″ straight-pipe insert bolts directly in place. As a result, it converts the muffler into a straight pipe and delivers an extremely aggressive exhaust note.
Khrome Werks 202712P Louvered Insert
This insert increases low-end torque while maintaining strong sound output. However, it slightly reduces top-end horsepower and deepens the exhaust tone.
Khrome Werks 202713P Decibel Reducer
This insert lowers exhaust volume to California-compliant levels. In addition, it meets SAE J2825 sound requirements used for state testing.
