My idea exhaust is to get 3.5 all the way to a electric cut out area. then the rest can be stock exhaust piping to the stock muffler and tips. Maybe find some way to add a cat or something to the back to get rid of the smell.
Then when i want to open her up i have the electric cut out for fun times..
