I had a complete muffler job at the Naperville location.Dec 2016. Covered under complete warranty I would have to pay for labor. If something went wrongJust 2 days ago a pipe came apart because it rusted broke off because of the way they installed the pipe Went back today they told me it would cost $800 to fix Weren’t doing anything about warranty they are terrible I talked to one of the mechanic he told me they should of asked my permission which they never did. I hope there is something corporate could something for me I am a single senior I don’t have $800 to fix my car
