Flowmaster Universal Resonator — Drone-Free Sound Control
Engineered to tame the frequencies that make a great-sounding exhaust unbearable at cruise, the Flowmaster Resonator attacks interior drone at its source. Developed in the Flowmaster advanced R & D lab, this universal exhaust resonator delivers a mild, refined sound level on tough-to-quiet applications, making it one of the most effective ways to fine-tune your Flowmaster exhaust system without sacrificing the tone you built it for.
Built for the long haul, this Flowmaster resonator features full 409S stainless steel construction in a durable 16-gauge material. It contains absolutely no packing materials, which means the tone you hear on initial start-up is the tone you keep for life — there is nothing inside to blow out, break down, or change your sound over time. That packing-free design is what separates true Flowmaster mufflers and resonators from the pack.
How It Works With Your Setup
The universal design makes installation flexible. Mount it in front of or behind the muffler, in new builds or existing systems, and pair it with other muffler types beyond Flowmaster — it is not limited to matching gear. It has proven especially effective installed in the tailpipes behind the mufflers in dual muscle car applications, yet works equally well in smaller-displacement truck and SUV setups. Whether you run a Flowmaster 40 Series muffler or another brand, this resonator exhaust component helps dial out cabin drone while preserving performance.
