Here is the hot tip of the century for ERA FIA owners !
I had a rattle in one of my mufflers, I cut the pipe off to see if I could find something loose inside that I could fix. When I got it apart I was shocked to find that the internal diameter of the muffler was only 1 5/8" and the 3" pipe was just butt welded to the muffler!!! I contacted Classic Chambered Exhaust about replacement mufflers, they can make pretty much any size and length you want. I ordered mufflers with their 2 1/2" core (2 1/4" ID) and a taper to blend the headpipe to the muffler. They can make a 3" ID, however they are unable to fit packing in a 3 1/2" OD muffler and it would be quite loud. I installed the mufflers and the difference was AMAZING. It is only a little louder, but has to be at least 50 more horsepower !!!
