Flowmaster Series 70 muffler and DRONE!!! HELP!!
#16
Update:
We put on a resonator. Helped a good bit, but there is still a drone... I am pretty pissed that I bought this muffler, had to add a resonator and still have that fart can sound. I should have bought the VT muffler instead it appears. I should have left everything stock and just been done with it.
Maybe it will get better as we go... The shop thought we could run a Cherry Bomb vs the resonator, but felt it would be louder...

I doubt its mufflers fault. Sounds to me like the y-pipe has been modified and/or no cat. Without any pics of the system or any real idea what you have its next to impossible to know. I do know with the stock manifolds if you put on an SPD y-pipe or get rid of the stock necked down y-pipe it can really make some stupid sounds and drive you mad. Been there myself. The root cause is the horrible stock manifolds.

resurecting this old thread (Wish i would have seen it before) Just put a 70 bb on my excursion everything else is stock. Drones like crazy! makes the whole truck vibrate when it does. I hate it. Exhaust shop is recomending a resonator as well. Really dont know what to do. maybe a magnaflow. I really dont want to hear the exhaust at all.
