| Dual Exhaust on a 4.9 Sixty Special
I'm just wondering if anyone has installed dual exhaust on a 1992 4.9 Sixty Special, Fleetwood or Deville. I want to keep my car stock but thought I would replace the stock exhaust with duals cause I think it would look so good and maybe get me a little better performance and gas mileage. Anyone out there do this? Your thoughts, comments. |
