What I have done, as have many others is have an exhaust system custom made, it is cheaper $ wise, than purchasing one from a company... Also, you can specify the size you would like. I have a custom fab 3" exhaust system, including the downpipe.<P>EDIT: You might want to just call around, and ask how much the custom ones are vs. the name brand ones, and that is when you will realize the price difference and savings.<P>
