2019 H-D trike exhaust
I’m told if you remove the catyaltic converter this reduce a lot of heat. Obviously there’s arguments over weather or not u need back pressure. American Customs alters your header pipes and says you don’t need back pressure. Other people are saying I would need to reprogram the bike. My question is this, has anybody put the American Custom header pipes on and did u reprogram the bike or not? How is the bike running? If I keep the stock mufflers on will the sound be louder without the converter? Thanks in advance.
