Once you add the code it takes away the free shipping and charges $15.
 
Oh how I wish someone would come up with a Turbo! I think Slee Off Road has one for a Land Cruiser

Find a local import shop that tunes JDM stuff etc. and get them to quote you out a full custom turbo setup.

I thought about this cause there is literally a shop less then a minute from my school, but since I couldn't afford it at this time I decided to save mine and their time
 
Again, CAI or CAT back exhaust provide no real HP gains. They DO provide noise though. If you like a whistle, get a CAI. If you like to hear a whine, get a CAT back exhaust. If you like a growl, get a vehicle with a V-8. If you want to sound simply amazing, get a Ferrari (going through a tunnel) lol. With that said, here is what will provide HP gains:

1. CAI+larger throttle body+new engine MAP+CAT back exhaust.
2. Supercharger
3. Turbo

If someone will show me a dyno run with only a CAI or CAT back and you get more than 1-3 hp I will be impressed. I will hear you coming down the street though.

Do you guys think Toyota would not do these minor things if they increased performance or efficiency? While I am on the subject, why aren't superchargers and turbos on every vehicle if the performance is so much better? The answer is cost to performance gained at the expense of durability and reliability. The truth hurts fellas.

You can lead a horse to water, but.........keep swinging that lantern buddy, I know somebody is listening. Be Safe.
 
How does one quantify the butt dyno measurements of hp gains from exhaust or intake?

The butt dyno is a logrithmic function of the smile factor. The bigger the grin, the more power you have to be making and sound does that for some folks. I changed out my back tire on my mtn bike last week and now my bicycle makes 40 MORE horsepower. I rekon with the mods to my bicycle (brakes, wheels, chain ring, pedals, tires, seat) my bicycle is now at around 120 HP.
 
Age old cross-polination of the "Muscle Car Forum and the Off Road Forum".
Even IF the CAI and Cat-Back produced REAL RWHP (lets say 1-3%, which would be huge) You simply would not feel it.
A noticeable change would have to occur very Low in the power band AND it would have to be 10%+ at the wheels which would be that plus 18% to account for parasitic drive train loss and the cost would be Thousands of dollars.
Real power is expensive.
Rule of thumb: $1000=10RWHP
The inexpensive gains are not practical and those are weight loss, something we simply do NOT do in the 4wd/off-road world.
So, my advice. Love it/wheel it/ IF you want a noise maker - put a Magnaflow on.
As for power adders (i.e. super chargers, turbos, strokers, whatever) say Good-Bye to off-road performance OR reliability OR fuel economy.

You guys are just plain silly.

Everybody knows Louder=Faster.

Straight back from cats

Sorry to bring back an older thred... First timer here.. I've searched several times and read as many threds as i could but don't see anyone doing a straight back from the cats.

Has anyone done this? I was thinking of doing an electric cut out and a turn down or run a pipe all the way out.

Oh a real engineer would not be rekoning but would be building one of these:
Build a Bike Dyno- calculate YOUR HORSEPOWER!

BTW, got new grips on mine for Christmas and I estimate my mtb is now at least +10 HP now.
 
Straight to the...

...Bad idea mod thread.
 
I know a lot of guys are running magnaflow and no matter which one you get they all sound great but I used to have the 24" on my old 3rd gen and it always seemed too quiet. On my 5th gen I got the 12255 which is 18" and couldn't be happier.

It has a tame note on the lower revs and anything 2.3k revs and up just sounds like angels blowing muffler trumpets.

Also put a tip on and had the installer turn the pipe straight out the side behind the tire. Had to be different than everyone else of course. Will post pics of you think you might like that look.
 
i have been watching videos and trying to gather research on a exhaust for my 5th gen. i havent been able to find a sound though however that doesn't sound like a tuner car. does anyone know if a setup that will give a deep throaty exhaust sound.

Yes. A V8.
