      Factory-Style Replacement. Sick of the smell of bad exhaust fumes or that terrible muffler sound? The Jeep Wrangler Muffler is designed to directly replace your factory muffler using the same specifications and mount points as the original. Not only will this muffler not interfere with the function of your Jeep, but it may even improve it a little.

      Roving Fiberglass Filling. Featuring a continuous roving fiberglass filling, this muffler produces a mildly deep resonance that provides your Wrangler with a little bit of kick as it accelerates.

      Turbo-Style Muffler. What this muffler may lack in aggressive sound outputs it makes up for in performance. In older Jeeps, this turbo-style design can help alleviate exhaust flow backups that limit the performance of your Jeep. As a result, you may even notice some small performance gains over your old factory original.

      Corrosion-Resistant Aluminized Steel. For extra dependability, this muffler is hot dipped in an aluminized steel solution that resists heat and corrosion. Fight back against rust and never worry about having to replace your muffler again.

      Application. The Jeep Wrangler Muffler is compatible with all 1987-1990 4.2L Jeep Wrangler YJ models.

      Limited 5-Year Warranty. A limited 5-year replacement warranty backs this product.
