In my opinion, the Magnaflow muffler is the best on the market. Granted a little more expensive then some others, but you get what you pay for. As for performance, it's there also with minor restrictions due to the straight through design. I dropped off a Flomaster 80 series off my 2000 TA and went to a 4" cat back with the straight through magnaflow. The 454LSx CI engine, CAME ALIVE ! The Flowmaster had too much restriction. As for noise, not much more then the old Flowmaster. I even put a set on my Dump Truck with a 427. Even it seems to run better, not to mention sound better ! 2 Thumb's up !
