    Abe - Back in 94 I had a 1989 Scotsdale with a 5.7 and 3spd auto. My mileage was around 11 - 12 on the highway. I installed Edelbrock tubular exhaust system which utilized all the correct emmisions. The cat was left in place and I finished up the system with the Thrush CVX catback exhaust. My mileage increased to 15 on the highway and it had a nice mellow tone to boot. I installed everything myself and the cost at the time was around $550.00 complete. Hopes this helps.
