Sounds louder and much better like I wanted. September 24, 2018 at 4:58 pm #2184 BigMoParticipant Here’s the link to the video with the cat still on and the oem dB killer remover.

O2 sensors changes the fuel trim for changes to exhaust and air filter. September 24, 2018 at 10:14 pm #2195 QwandreeModerator Niiiiice. My leo vince is on the way from italy. Not running lean at all after the decat?

Duke 690 didn’t need a remap after decat but this engine is not the same. Author Posts Viewing 9 posts - 1 through 9 (of 9 total) You must be logged in to reply to this topic.
