    Muffler delete interesting problem

    So I’ve installed a delete. And it’s great. After 3K revs. there’s a bit more drone than stock (with valve unplugged) but not unbearable. The problem I’m having is city driving between 1000-2900(ish) k revs it’s very boomy. Would a silencer or resonator combat this ? Because it sounds lovely...
