a mustang isnt a mustang without some exhausts....plus the fact that your car is going to be a classic in another 5-10 years...

i my self would keep it street legal...flowmasters with cats...to pass inspection and what not...basically what i have (sig) i would do first to any mustang....makes it quick off the start and sounds sweet, especally b/c it wont break the bank, and its a noticable difference!!!! GEARS GEARS GEARS
