new owner of a 98 GT it has a flowmaster exhaust which I would like to make louder eventually other then that it's stock. But what are some good mods to start out with. Any advice ?
Hey now. I hacked off my cats because I'm poor.You car is a SN-95 also less known as a FOX4, not many refer to their 94-04 mustangs as FOX4s but it is still technically correct terminology.
BackPressure was recommending you cut off your rear cats and I was trying to tell you not to do that. Save your energy and wait until you get an aftermarket exhuast mid pipe.
