Isaac has a 94 dx. I have a 96 dx with a ex vtec motor. We raced today at the end of his road and HE beat ME. He can change gears a little bit faster than me but his only mod was a autozone muffler
. His car accelerates a lot faster than mine. I know my engine is in good shape because i had a tuneup right after i bought the car. Is it built up inside or can i just not drive?
