Like the title says... I'm looking to change out my 98' 2.5L muffler and don't want to deal with the dreaded drone of an after-market one. I heard a 03/04' Boxster S muffler will work, but I'll need to get the proper mounting bracket. Is this true, can a later model muffler be swapped into an older car? If so, would the bracket just be an 03' or is it something different...
