This thing is ok on the highway but wont get out of its own way around town! the drive home was 96 miles door to door, driven between 65-70 MPH maybe slightly more at times. I know its the 3.00 rear ,but come on!!!!! Changed the oil, pcv and air filters before the trip. It has a hole in the muffler, gotten larger after the good blow out trip home. The ex. appears to be stock all the way back, y pipe to single to muffler.Tranny fluid was a light pink . Seems like your getting going good and making power and it shifts !!! argh!!!!
