Again, you have to think of your car's engine as part of a LONG pipe...starting from the air intake to the air filter and ending at the tailpipe. If you don't do stuff in the middle, doing things at either end really can't alter the situation a great deal....a little but not much if you look at it this way.
As known with the 5.4s I have exhaust manifold problems/ w/studs. The passenger's side has a crack in it and the drivers side needs to be removed, magnafluxed/planed and put back on. Should I replace them with headers or replace/repair/ the stock ones. If headers are the trick, what about sensors and stuff- one hypo shop says they aren't an issue, but a Ford dealer says my engine light would be onall the time (Ford dealer I believe was assuming). One guy told me to keep stock remove the muffler and run straight back off the cat. (sounds gay)Should I take out the y-pipe and run duals to the back? What has someone tried and figured out before I spend time and money with this thing- I want to get more HP out of it if the price is all the same. Am swapping in a Airaid air intake system too.

Think of your system as ONE LONG TUBE....you can open one end and then the other end but as you can see, if you don't do something to the middle, the returns diminish rapidly no matter how much you spend opening the ends.
I don't know enough to advise you on how you might cam this motor but you need to think this out in terms of a total process...if you are putting more and more air into the engine then you need more fuel to get more power. The only real "power" in air is if you turbocharge, and even there you'll need intercooling and bigger injectors to tame all that hot air.
I'm sure the many vtec boards have figured all this out.
I am looking particularly for headers and a supercharger and possibly a way to disable the governor's chip? I top out at around 110/115? I am fairly new to this so looking for all the help i can get to make my JGC as quick as possible (I got the 5.7L cause I wanted the tow package just in case (I live in PA) otherwise I would have got an SRT-8) But it is nice to take off the emblems on the back and watch the rice-burners cry
Currently I have:
AIR-AID Mass/Cold air intake w/tube
BORLA Cat-back exhaust
JET Stage-1 Chip

here's a good reference site for you, and it has a # you can call to ask this question:

That's why I tell people there is NO power in a muffler or a free-flow air filter. Usually you get the most power by removing both of them, so they can't "create" horsepower, then can only release a little more that might (or might not) be trapped in your engine.
was installed and now when you accelerate hard from a rolling start the temp gauge drops to near zero (acts like a vacuum gauge dropping to zero under full throttle). Does anyone know what could cause this?
Thanks, Ben :confuse:
Would a higher flow exhaust system, for example a Flowmaster muffler series 50 or 60 help, in addition to removing the twists and turns in a Highlander's exhaust system ? I have not found any catback systems for Highlanders. Would I really have to replace the catalytic converter, too? Or how would I know if the stock catalytic converter impedes exhaust gas flow? I also assume there are EPA regulations on catalytic converter replacements, too.
