Achieving 20-22MPG
#26
Exhaust isn't going to make a difference, I wish people would understand that. Everyone sees those stupid commercials and think they're gaining HP and MPG's
Probably because he doesn't know how to calculate MPG, or his driving habits changed

BTW my buddies exhaust is a full headers and everything back system. It's got a fake cat that just a pipe, a resonator, and a fart can on the back. No o2 sensor either. If that changes anything....

I don't care what he tells you, driving more aggressively will decrease mpg's. He probably doesn't know how much his tank holds (including reserve)
Cars and trucks are tuned from the factory with the factory exhaust. Changing the exhaust will not make a huge difference, it will really not be noticeable
The only way my MPG's changed was my driving habits got better, not because I have a Flowmaster

For sure driving more aggressively decreases gas mileage but that just goes to show that even on top of worse driving habits the new exhaust improved his MPGs that much more.
I think part of it in his situation was that the stock exhaust was so so badly clogged up that it was hurting his gas mileage. Has he put a completely new stock exhaust system it might have gave him the same MPG increase.

I think the lesson we've all learned here today is that you shouldn't be clogging your cat up with anything at all. in fact, just don't even own a cat. dogs are better anyways.

My 2002 3.0 2wd (stock tires,225-70-15)only gets 19, city/highway makes no difference, always 19. I know it will be less with ethanol but I wont have those numbers till after I calculate a couple tankfulls.
It kills me that guys with taller tires and 4wd are getting better mileage than my truck.(assuming they know how to accurately calculate mileage)

Personally I'm just gonna get a high flow cat from Summit for $70.

Those things are a life saver, we used them on my aunts 02 mustang when we put a full magnaflow system in it.

i've always thought that was a stupid system. good ol american units we just say how tall, how wide, and what size wheel. give a ratio and you have to do math to figure out how big your tire is.... dumb dumb dumb.
