Im thinking about buying the Thrush Turbo Mufflers for my 91 SHO. What size do I need? 2 inch or 2 < inch? I had these on my V8 SHO and thought they were too mild for that car, but on my v6 I think they might have the right balance of being not too loud but aggressive enough. Any thoughts? Thanks, Ryan Staley Pittsburgh, PA 91 Red SHO (14.807 @ 97.91 mph)
