On the exhaust setup you were telling me about, what size pipe do you have run before and after the muffler? Do you think I need to run a smaller size after the muffler to keep back pressure? Like a 2.5" inlet to a 2.25" dual outlet? After thinking about it, I like your setup and it's much cheaper. Now I got to find out if IMCO makes a DI DO muffler. Thanks.
