I have custom made side exit exhaust on my car. There is not a lot of room to make a muffler fit! I was running 40 series FMs. I had to switch to a racing muffler since it is shorter! I want to get back to a FM, but it just won't fit! Does anyone know of a shorter muffler for me? I thought I found a FM with the inlet and outlet on the same side. Turns out the thing is huge! I also read is ran on camaros and fireturds! I was hoping one of you might be able to lead me to one. I guess I need to find out what amount of room I have to play with don't I. Thanks!!
