Is this Arrow muffler titanium or steel @macduff?
I wear good ear plugs and can still hear my 2017 EX at idle.
But I can't hear the garage door opening or closing.
Nor can I hear a transport truck idling 30 feet away.
At highway speed I can hear the hum of the mufflers.
If I crank the throttle I can hear them howl.
Nothing quiet about the mufflers on the 2017 EX.
A further note on running these without baffles . In the week or so I did this the part throttle cruise became a little on/off jerky which may mean it leaned out more than the o2 sensors /Ecu could adjust for. Baffles in and it’s nice and linear.
