4runner.
Had Flowmaster Super 50 installed and the resonator removed (bad decision). Drone like crazy. I checked on 4runner forum. 99% of the member states NO drone if you remove the resonator. That is a load of B.S. You have to be tone deaf...if you dont hear the drone at 1800-2500 RPM. Below that RPM band, no drone. Above that RPM band. No drone.
Came back today. Had a Flowmaster 2.5" branch resonator and small Dynomax minibullet (using as a tip) resonator installed. Welded.
LOVE IT!!!!!!!!!!!
No drone. Yes.I went overboard with two resonator....But no drone (maybe a hint)....at all RPM band. Step on gas. Nice flowmaster note. Now I can cruise without ear plugs.
These guy did a great job.
