I'm thinking of deleting my rear cats on my 98 4.6 liter. But my buddy says just doing the rear cats sound funny. What yal think or has any one done this before with chambered mufflers or slps
i got my rear cats removed with a flowmaster 10(chambered) muffler. it sounds pretty good. If you take out all 4 you have to mess with engine codes and such
just do the rears. You cut out all 4 the engine is going to throw codes all over the place and it won't run right.
