depending on your driving, it could increase up to 4 or 5 mpg. But gas mileage will be determined by driving style.
no
no lol its just louder it adds 50 hp what if the twin exhaust is the some size of the single exhaust
The GXP is the Turbo Charged one. Instead of having the 2.4 single exhaust engine that the NA has. It has the T/C 2.0 dual exhaust. Which produces more H/P and better gas mileage.

Dual exhaust and P71 210. Single exhaust 190
For a 1998 Lincoln Town Car : It depends on which state it is sold in and if it is single or dual exhaust Single exhaust ( 200 or 205 horsepower ) Dual exhaust ( 215 or 220 horsepower )
by having a exhaust shop weld on a y pipe then just run the dual pipes out the back
V6 Dakotas come with "dual exhaust manifolds". If your asking about exhaust systems, all I've seen are singles in and out or single in with dual tips (mufflers). The pipes to the mufflers is Y-pipe to single.
1) Poor gas mileage 2) Dumping pure fuel into exhaust system (possible ignition and fire) 3) Plug catalytic converter 4) Won't pass emission test

As a rule exhaust is emitted on the opposite side of the fuel filler tube on single exhaust vehicles for safety reasons.
If this is on a vehicle that needs to stay emissions legal, then yes, you need to keep your cats. Otherwise, you can remove your cats and it will remove some of the restriction in your exhaust system. This would translate to more horsepower, torque, and a little better mileage. You'll also have a smellier exhaust. As for single vs duals, that will depend on your engine. If you let your exhaust piping get too big in diameter, your exhaust gas velocity at low RPMs will drop, and you will feel a loss in low end torque. You might see an increase in peak horsepower. For a large engine (making 400+ HP), you could still be fine with a single 3 inch exhaust. If you really want the dual exhaust, at 400 HP you probably should go with 2 inch piping. Maybe 2.25. Any larger and you risk losing low end torque. If this is a 4X4 going mudding, or going to be an exclusive track car, you could go larger, because you'll be keeping that engine at higher RPMs. If you want the dual exhaust look, but want to keep the low end torque, there are mufflers that take a single inlet and have two outlets. This would allow you the best of both worlds.
