"I put this system on my 1998 Mustang GT. I am very happy with this flowmaster system. The only one thing that I don't like about it is that I have 275 wide tires on the back of the car and there is not as much clearance between the tire on the passenger side as the original exhaust. The bends should be changed slightly to give the same clearance as the original. Note that this would not be a problem on cars with tires that are not as wide or have different wheel offsets.
Other than that issue, the system sounds great, was easy to put on myself, looks good, and was priced right." —Kevin K from Eastlake, OH bought a Flowmaster Exhaust Systems for a 1998 Ford Mustang, GT, 4.6L V8.
