Oh, and don't forget (This is my little secret.) Cut off the elbow at the end of the tailpipe so that the exhaust flows straight out the back. That way, you get a little "rocket engine" effect from the exhaust pushing rearward.

If you leave the elbow in the pipe, it throws off your alignment because your truck is constantly being forced into a right turn. Hurts your tire wear, too. But you can get around that problem by switching to dual exhausts.

Seriously, the best way to increase mileage in your Tundra, is to drive your wife's Honda Civic when you make trips to the 7-Eleven for beer.

Dont forget the big WHALE TALE on the roof for improved aerodynamics.

The whale tale is a must for the rear. If you put the whale tale on, you'll need the aerodynamic windshield wipers from k-Mart for the front. I prefer the big pink ones.

Sorry about the hijack......

I forgot to add the "fuel ionizer"

This is all you need:

Unfortunately I don't see anything that fits a Tundra, but maybe we can do one of those petition campaigns like Pistolpete did with Weathertech!

Funny you mention the ionizer.
I had a customerwho swore up and down he got 3-4 mpg better with it.
I then proceeded to show him he had installed it on the VACUUM hose to the brake booster.
He walked away in a huff
Nuff said

The "reasonably affordable" part of yer question threw me. I was gonna say, see if it will fit in the back of a Dodge Cummins...

I think I will start walking since I cannot afford gas

Many people claim that adding 4 to 6 ounces of acetone to a tank of gas will get you an extra 3 or 4 MPG.

Acetone is nasty stuff and will strip paint if you spill any. I've been using it in my old scratched up 2001 4x4 Tundra and I noticed a significant improvement in power.

My transmission clunks when it shifts into third gear, but it only does that when I don't have acetone in the tank. I'm not sure why that is, the only thing I can think of is that transmission shift points are programmed to react to engine vacuum inputs, and that the acetone improves the vacuum significanty enough to alter the input.

I'm too lazy to check gas mileage so I can't tell you if acetone helps it any.

I read in the paper about a woman who was carjacked. She told the carjacker "Take my car, but please don't take my gas!"

What a load of crap.

I am all over this, the whale tail, the tornado, TRD stickers.
I think with my new found mods, I'll get around 400 HP and 60-63MPG. SWEET!

I found that removing all of the catalytic converters in my exhaust in both of my Subarus helped gas mileage tremendously hah. Then of course you battle with the fact that you have to get it registered somewhere where they don't test for emissions =p

I finally got a good read on my '06 Tundra AC V8 gas mileage on the highway -- 22.8 mpg. This was achieved at a steady - and I mean steady -- 65 mph on flat road. My only mods are a Flowmaster y-pipe, Magnaflow muffler and 3 inch single exhaust, K&N air filter (leaving in the factory emissions filter in air the box), and Undercover bed cover.

As for removing the cats for better mileage:
There was a newer Ford pickup in front of our van pool the other morning in stop-n-go traffic. It had a modified exhaust system that was quite loud. The big bust was that it stunk, I mean really stunk, like cars from the sixties -- obviously, no cats. I tried to get the licence plate to call him into the CA Air Resouce Board but got ahead of us in traffic. If we all have to comply for very good reasons to have cleaner air to breath, why should one person be allowed to ruin the air for everyone else? (kind of like a heavy smoker lighting up on the bus.) I'm running a hi-po cat on my 1971 chevy just to do my part for cleaner air. Wouldn't removing the factory cats screw-up the ECU's ability to properly run the engine?

The only problems you're going to run into when removing cats are catalytic converter inefficiency CELS, which is easily fixed with mechanical, electrical, or engine management fixes. It shouldn't cause any problems with how your engine runs because they're just part of the engine's exhaust system.

I used a high flow cat in the downpipe of my old ~300whp WRX. It would have passed emissions and gave me a noticeable increase in fuel mileage when the other cats were removed. In a turbo'd car though, you do lose some spool if you leave the cats in.

Awhile back this was discussed (for about the 20th time in TS history) and I said that I would give it a try.

Well yesterday I filled my tank and put 2 ounces of acetone in *carefully*. I haven't driven it much, maybe a total of 30 miles, so I can't say anything about the millage yet. What I can say, and honestly this is not the butt-o-meter talking, it does idle smoother. I always figured it was my loud exhaust that made the truck idle kinda rough, nothing outragous...just kind of a bit shaky; normal in my book.

As for the increase in power.....can't say, and probably never will be able to because the butt-o-meter is not that accurate!

I'll let you all know if my millage improves at all. If it does work I'll be happy because I have a 2500 mile trip to Florida coming up, and if I can safe any money on gas by using this that will make me very very happy!!
