bigbl62 Posted January 17, 2005 Report Share Posted January 17, 2005 I recently added a Radix to my truck, shift kit,headers,pcm4less. When I first got the truck I installed a flowmaster muffler. My mechanic is saying now that I did all of the upgrades I should look into a straight flowing design muffler instead of the Flowmaster. He recommend the magnaflow. I love the sound of the truck now. I wouldn't mind if it was a louder. Should I swap out the muffler? What would be the difference? Hp,sound,etc? What are some good mufflers out there that would sound good and add some horespower?
