MBRP has just added to their quickly growing line of GT500 mustang exhaust. These new race and street cat backs are for the 2007-10 GT500s. MBRP Tested the street version and it made 27HP and 17Ft Lbs to the Rear Wheels. Thats very good, but the Race version made 41HP and 25 Ft Lbs!
These test were done on a stock 2007 GT500.
