2007 Shelby GT500 Muffler Upgrade??
I just bought a 2007 Shelby GT500 convertible and am loving it. Except I cannot say I am inpressed with the exhaust tone= too quiet at idle and when accelerating! Can anyone advise what muffler change they have made and what would you recommend (Flowmaster, Borla, Cessini, etc?)? My bud changed to Ford Racing muffler but not too impressed?
Any websites to "hear" the new sounds, any magazine articles on this?
Last, what do you think about change to aftermarket cold air intake and/or K&N air filter??
Thanks for your input, Ron.
