I believe that my new 2015 Foreman has a Cat built into the muffler behind the O2 sensor. (If someone knows I am wrong about the presence of a Cat in the OEM Honda muffler please let me know),,, I have decatted quite a few Harley Davidson exhaust systems with great success without any remap of the ECM as long as the intake system is left alone. The Harley ECM has limited ability to adjust fuel mixture and timing for the decreased back pressure in the exhaust up to a point. The advantage to doing this to a Harley is a huge decrease in heat in the Cat area & improve exhaust note, (sound),,,,
Has anybody tried this on these late model fuel injected models? I am interested in the outcome.
Thanks,
Dwayne
