They installed a new muffler in my old Subaru earlier this week. They called me to discuss and gave me a quote (only 99 dollars, including installation!) before beginning work and had my car done exactly when they said they would, which only took a couple of hours even though I did not need the repair done quickly. My car sounds great and I will definitely use them again.
