Best Exhaust Resonators: Remove the Drone and Improve Performance
Tune your car’s exhaust with these top exhaust resonators
The Vibrant resonator is constructed of stainless steel, withstands high exhaust temperatures, and features a "true straight-through" perforated core. It comes with a five-year limited warranty.
The welds are good, and the unit is very solid. This resonator facilitates undisrupted exhaust flow and removes nearly all the drones and overall volume that is common with an aftermarket exhaust.
This resonator doesn't fit all vehicles. While it reduces the drone, it's not "ultra-quiet" as the product promises in the description. Also, your vehicle may still be loud when cold starting.
This stainless steel resonator is 12 inches long, features a 2.5-inch inlet/outlet, and has a 4-inch body diameter. It withstands high exhaust temperatures and is designed to produce undisrupted exhaust flow.
This resonator is a great, high-performance addition to replace OEM equipment. It produces little to no drone, cleans up the exhaust note, and takes the rasp out.
It may not reduce overall sound as much as you want or even bring it down to noticeable levels. Also, the welds may start to deteriorate after a short period of time.
This pair of resonators fit any 2.5-inch cat-back exhaust system. They are 18-3/6 inches long and feature a 2.5-inch inlet/outlet diameter and 4-inch body diameter.
They sound good even if you weld them on to 20-year-old stock exhaust pipes and headers. They make a difference in responsiveness, are just loud enough, and aren't too raspy.
These resonators may not make much of a difference unless you do a complete exhaust job on your vehicle. Also, you may still hear some exhaust drone when they’re installed.
