Hello, Im currrently in Aghanistan talking with some buddies on mods that we want to do on our vehicles upon our return. Now what i want to do in particular is put a CAI on my 99 Tahoe along with a throttle body spacer. I already have the Flwmstr cat back with a KN filter set up; now my question is will I get a lil more mpg‘s with those few additions? Im not necessarily interested in power, although I do tow every now and again. im also easy on the pedal as well, so help me out gear heads, will that be a good invstmnt and will i be looking at a slight increase in mpg‘s? Thnx

The theory is, any energy it takes to build up pressure in the exhaust system is wasted energy. It is possible to free up 4-5 horsepower by replacing an entire exhaust system, though most of the gains are at high rpms, the exhaust will be louder, and you will lose some torque at idle. If you are attempting to increase power through other means (bigger valves, less restrictive intake, bigger carb, or adding a turbo) then you may need bigger exhaust to see the full benefit of the other modifications. A crack in the exhaust costs power if it is before the O2 sensor, it means your fuel mix is set based on faulty information. That can lead to poor combustion, bad emissions, less power, more fuel consumption, and possible engine damage. It can also lead to carbon monoxide poisoning for people inside the passenger compartment.

cold air intakes have the potential to increase mpgs. they provide a little more air flow which assists in acceleration, which the theory that if you get to your speed at a better rate(better acceleration), the less gas will be used in the process.so if a CAI slightly increases acceleration potential, you can have an opportunity for slightly increased mpg if you aren't too heavy with your foot. I've wanted to try a throttle body spacer on my truck, as I have heard good things about an increase in numerous things, such as power and better mpg's. upgraded exhaust doesn't really do anything to help with mpg's; it's all in the manifold. if the manifold doesn't conduct the flow of exhaust gases accordingly, the exhaust afterwards is pretty much useless for performance. that's what headers are for. they are better designed to relieve backpressure on the exhaust valves and allow for a better outward flow of exhaust gases, rather than compressing them at the highest point of the manifold, as stock manifolds do. that's basically as far as you can get with the non-muscle car today.
