Does your Billy Boat exhaust drone ( resonate )? Which BB Catback is yours? Pics?
Is Magnaflow the best catback for the H3?
I want a more free flowing system with a deeper, more throaty sound without any drone.
Thanks

My Billy Boat is the following Hummer H3 Exhaust Applications from Billy Boat Performance Exhaust
The Product is very good. Inside the vehicle the comfort is perfect. Outside the sound is good but not so strong. I would like actually a deep tone. A guy suggested to remove the resonate (kind of oval thing see pic) and after removing it I will get a deep tone. He said that without the resonate the results is: it is loud as hell. So I will try it.

yeah i chopped mine off and replaced it with pipe. no issues with bad smell. FYI cutting it off made absolutely no difference in tone on the V8. The muffler change made the difference. the resonator is a straight pipe in the inside with a double wall, no baffles, no insulation, the exhaust just freely goes right through it.

I appreciated the H3 flowmaster videos and sound....however...I just installed the 80 series and it sounds great at idle
...but I dont like the sound between 30-50 miles an hour...sound to much "drone" ...air flow does not appear to feel smooth/combined with the poor sound...
...thinking what to do next???...I heard 50 series was the best...but I listened to the tech...thinking he understood the engineering better /etc...what to do...lol

Di you mean the resonator? In fact I do not see any O2 sensor around the resonator. The O2 is around the catalytic converter, right?
Straight pipe size to exhaust?
