Angry™ M8 Stepped Core Baffles (2"-2.5")

(specify Level II, III*, IV*, V* with order)       * Angry III & IV, V require an SE or Aftermarket Tuner for 107 motors, Angry 1 & 2 do not unless other modifications have been made to your motorcycle such as intake and CAT, M8 114's are fine up to Angry 3 as well with no other modifications to the bike. We recommend Angry III on Stock 114" and up, or Angry II for allot of mostly downtown city riding depending on the local by-laws.

2017+ Milwaukee Eight Touring  - Developed Specifically for the M8 our Stepped Baffles Enhance the M8 sound and aggression as much as possible without detriment to the engine. The BIG difference with our 2-step baffle? our 2" inlet is the nature next-step up from your stock 1.75" headers, then we step-up to 2.5". - Tis aids in keeping the speed of the exhaust gas higher then "falling" into a 2.5" full length baffles. We also achieve a unique sound in the market due to the unique exhaust flow-path when combined with our tuned end caps. 

Disclaimer:  A stock engine tuner is sufficient for normal everyday street use, if the only engine/intake/fuel system modification you have done is your Forsch Mufflers! However an Engine Tuner is recommended (along with high flow intake) to fully appreciate these pipes, and if any other modifications have been made. Please note as with a stock / modified engine/exhaust,  Damage wear & tear may occur faster than normal by practicing aggressive riding such as applying instant full throttle at low RPM's! - read the HD manual - they don't like it when riders crank the throttle in a higher gear at low RPM vs gearing down and increasing, increasing RPM and reducing engine loads - if you pound it it all the time it will break, if you find you are always on the throttle - it could be time for Cams, Compression Increase, Bore kit etc.

These head pipes have been dyno-tested with our Angry slip-on mufflers, and have had excellent results. We mimic the older-school sound and performance of a 2-into-1 head pipe while reducing the sound and heat level on the right side of the motorcycle by keeping the factory cross pipe. Approximate gains of 10 HP and 10 ft lbs of torque on a stage 4 128 SE (see Dyno chart here) using the factory SE tuner and custom tuning. Expect more or less depending on your modifications. This head pipe also utilizes your stock heat shields.   Price includes pick-up and return shipping from and to you.
