I was quoted $200 USD to have my stock muffler replaced with a flowmaster super 10 (I already have the muffler in hand, leaving resonator stock). I was told it would be about $80 to replace the muffler and $150 to add the piping needed to connect the muffler to the dual outlets, and I could get it done for $200 out the door. Does this sound like an accurate/fair price? I’m new to this kind of stuff so unfortunately I don’t know myself. I’ve seen some posts here with people saying they paid roughly $100 while others said they’ve paid upwards of $400.
