Re: exhaust help...fast!!
My buddy has duals on his 89. The way he has them routed is by going just on the outside of your gas tank sheild and in between the leaf springs. There are dropped down a little bit though because if they were directly between the two, they wouldn't fit. You also have to use 2" or 2 1/4" tubing because 2 1/2" is to big. Hope that helps ya out some.
