I used the LMC duals and stock manifolds. No AIR tubes left the bungs in. 17.5 mpg highway (confirmed) and 10.5 city (guessed on city). One reason I like the 1987 it is still simple enough to work with.

I have the K&N air filter and TBI/carb spacer. The LMC exhaust has held up for three years now and no leaks. I used the turbo mufflers and every thing fit well.
