Dual exhaust only has advantages for V8 engines or high output V6 engines, To get the best performance from a dual exhaust you would also need to increase the air intake as well, the two combined increases the efficiency and the horse power of the engine but the ecm will have to be tuned to accommodate the physical changes in the system. So it could get a little pricey.

Hello, On that engine, it will allow it to breath better, and have more power, and better mileage if you drive it decently. Dual Cats/mufflers/resonators on the 6.2 from the factory is the only to order these babies; moreover, on the ones without, the heat under the engine compartment is HORRENDOUS. Three to Four year old Sierra's/Suburbans without duals show their age much faster,...Hoses, alternators, water pumps, and on and on. Hope this Helps, AskTrannyMan PS: The majority of 90 thru 2010 Town Cars/Crown Vics came with duals or was a minor charge for the option when ordered.
