B-Day Present
My dad's birthday is comin up and I wanted to get him a replacement muffler for his 2000 F-250 SuperDuty. Its a stick with the 5.4L engine. I was lookin at the flowmaster 40 series (my buddy has that muffler on his F-150 w/4.6 and its sounds nice)...jus want the muffler, not the system. I'm curious if any of you are familiar with the size (diameter) of the cat exit going into the muffler. And if it would require much work to put that muffler into the factory setup. Any info on this would be greatly appreciated. Thanks--
Ray
