I want to put dual exhaust on my 1994 crown vic. what do i need to do this

I am not sure but I am betting that you would need to have the motor tuned for it or something else done. I do not believe that you can just have dual exhaust put on and not have something else done, I could be wrong. I am wanting to do the same thing to mine.

Florida's kind of flat. Do you need to update the handling? If so, consider a set of Bilsten HD shocks. The run about $90 each on sale though. I have Dunlop SP5000 sport on our Taraus and we are pleased with them. They make the size for your car too. A word of warning though. Do all four times. The Taruas had severe oversteer when we changed only two of them. We went back and bought the other two becuae is was unsafe to drive. With all four, the car drives like it's on rails. Others with the CV like the Michelin Symmetry. I once had the Goodyear rain tire that had a prefered direction, fancy tread pattern and what not. It was most unsatisfactory on my Chevy Caprice. It wanted to follow any groves or camber on the road. Granted the Caprice was well worn. When I got Dunlop cheap tires on it, the car controlled much better. That's my experience. I'd be interested to hear what others thing. ~gator~
