This is the sequel to ZZP's popular 2.5" straight through resonator that we use in the Ecotec/Sonic/Cruze/and other cat backs. Our smaller version provides 75% of the drone and noise dampening of the larger resonator at almost half the size. The 3" version measures 16" end to end, with a 10" x 5.25" body.
Our unique three chamber design cuts rasp down, gives your exhaust better tone, and helps reduce overall volume on your system. Many competitor's (Borla, Vibrant, Flowmaster, Dynomax, etc) resonators are fully straight through or lack the quality packing that we use, meaning only a slight change in tone and still leaves a lot of rasp. You can put these resonators basically anywhere and they will still provide that great ZZP exhaust note you've come to expect.
