I have used this shop for emissions and muffler changes for the past couple years. The muffler I put on two years ago was $175 in parts and $50 in labor for a total of about $225. The muffler had a factory defect and broke at the welds. The part had a lifetime warranty and the shop replaced it but charged me $50 in labor. The replacement muffler looked cheaply made and am concerned it will break too. I asked about an upgrade to a Flow Master but we couldn't find an agreeable price. I wish they had a better labor warranty but it's probably standard. Also think they could have done a little bit better for customer satisfaction. Overall I am satisfied with their work and glad to have a muffler shop in Henderson. Especially like Dave who does the work. He's a top notch guy that cares about his quality of craftsmanship.
