Vibrant SS Resonator (Standard Design) 4in inlet/outlet x 18in long w/5in OD resonator body

This is a Vibrant Performance standard bottle style resonator. It's built from 304 stainless steel, which means it's going to hold up well against corrosion and the elements. The primary job of this resonator is to cut down on exhaust noise, specifically the drone and rasp that can sometimes come with aftermarket exhaust systems, without creating a lot of backpressure. It features a true straight-through perforated core, designed to let exhaust gases flow freely while the packing material inside does its work absorbing sound.

With a 4-inch inlet and outlet, this resonator is sized for larger exhaust systems, and its 18-inch overall length with a 5-inch diameter body gives it a good capacity for sound dampening. The design is straightforward, making it a popular choice for custom exhaust builds or for adding to an existing system where you want to quiet things down a bit. It's a well-built piece that's made to last and effectively reduce your exhaust's decibel levels.
