I just got a 1989 nissan 240sx coupe and it is in fair condition but it is a definite fixer-upper. What is the best type of exhaust to put on it but none of that rice rocket farter stuff? Also my dashboard is cracked and the interior is shot. So basically what should i do to this car to make it decent without spending lots of money on it? for the engine it runs fine except first gear shifts hard, so what i think is the guy before might have put in a chip and changed the shift point....so is it supposed to be shifting hard and can i fix it.

thanks
