Going to get a new muffler for my 3.4. Don't want to spend the money on the Borla or even magnaflow. SO, going with the flowmaster. I heard that SLP Loudmouth was unbearably loud in the interior. I currently have the 1in/out and am going to get the 1in 2out. What series of flowmaster should i get?? Anyone got one? Also, heard a camaro with an unknown brand of muffler. Sounded great at idle but bad at speeds. Will flowmaster do this to me??
Thanx
