Just had the local muffler shop swap out my stock muffler for a magnflow muffler... WOW!!! I have watched many uploaded videos of magnflow mufflers and NONE of them do any justice to the true sound that comes out of those tail pipes. I am very pleased with how grumbly it sounds at idle, how it growls when you open it up, and how it gets flat out mean at WOT. I am thoroughly convinced that I have made a wise purchase. I can not wait for my AFE Stage 2 CAI to be delivered. I am so excited to see how well these two upgrades work together.
By the way, props to the muffler shop. Paid $150.00 cash for the muffler and install.
Purchase and install both took place at Brad's Muffler off of HWY 6 between Santa Fe and Alvin. The part number is 12278. It is the 18" case. They recommended that I kept the stock y pipe and said that it was actually very free flowing. They have been in this business for a long time so I value their suggestions highly.
