Automotive enthusiasts beware! Based on our own experience, this muffler was a letdown. The pros? It looked good and gave a slightly deeper growl to our car .unfortunately, the cons far outweighed the positives. The installation was a nightmare and required professional assistance. Even after installation, the muffler did not provide the promised increase in horsepower and had a noticeable drone at highway speeds. Save yourself the headache and look for a better option..
