I have a 94 GT with Flowmaster 40 series. I am not satisfied with the loudness of the exhaust. The tone is great, I am very pleased with the sound. I want to amplify the sound but don't know how to go about it. I guess my best bet would be to add an X-pipe or H-pipe of some sort. I just want a louder exhaust that is not too obnoxious. Any help would be greatly appreciated. Thanks.
