89 GT convertible. All stock except for BBK cold air intake (even rims are stock). 10K miles.

What are the next recommended mods for a not-so-technical enthusiast? We did a complete tune-up and the car runs fantastic. Not trying to get into tearing the motor apart, although this may be my only option for next mods. I hear that gears should be next, and I know I should get come flowmaster mufflers. Any ideas?
