Wow I am truly blown away by the quality and sound of these !!! Flowmaster you deserve every penny for these. They even make this very cool burble sound when im down shifting....totally unexpected bonus. The sound of these on my 07 mustang GT are outstanding....Flowmaster knew what they were doing when they made these !!! My car sounds like a mean monster and they added HP too. Thank you Flowmaster and Amazon !!!
