Hi my name is Landon I've owned three 88 mustangs all 4 bangers lx's all hatchbacks. I bought one from Vancouver that had some mods on it and I really need help on finding out what was on that car first off all it had a custom exhast with glass pack pretty much full straight pipe with glass pack by the axle very loud, second it must have had a different differrential in it cause all three of the stangs I've had have all gone 90KM an hour at 3000 rpms well this mustang I had went 90KM an hour at 2500 RPMS and it would smoke alot of cars cause I could reach a really high top speed but I have no clue what differential gears to put in which really ticks me off. and all this talk about the silencer I never heard of doing but im gonna try it I need some tips on that as well please if anyone could help me on the differential question that would really help thats my main problem thanks alot have a goodone! and both speedo's were tested and both were accurate so it's not the speed
