I have a '98 Blazer 4x4 rebuilt motor, newer transmission, new cat back, all new brakes (calipers, lines, rotors, pads) new front axles, new front suspension, newer fuel pump, etc... nothing on this truck is old... it does have higher BODY miles, but it runs like a top... it does have a slip on cat, so it's not loud, but it's not quiet either....
