Our verdict

A single cat-back kit for the listed Wrangler years, aimed at a mellow tone. The listing gives two different pipe sizes and lists no warranty, so confirm the fit with the seller first.

Overview

On a Jeep Wrangler YJ, this Dynomax kit replaces the exhaust from the converter back with a single system built around a Super Turbo muffler. Fiberglass matting inside the muffler absorbs resonance for a mellow tone.

Dynomax pitches this as an upgrade for the named Wrangler that channels flow and reduces turbulence while staying quiet inside. The listing disagrees with itself on pipe size, and the warranty row reads no warranty.

Who it's for

Owners of the named Wrangler who want a replacement rear exhaust with a mellow tone will find the muffler design matches that goal. Anyone with a later Wrangler, a different Jeep, or a need for warranty cover should look at other listings.
