The only real difference removing the resonator makes is sound. If you're referring to a performance difference, then you've fallen for a placebo.

now now perdue, everyone knows louder more obnoxious sounds make a car faster!

...it's the only reason anyone with a brain would put a fartcan on their exhaust...

say what you want to, and anyone else can make whatever joke they want to. Even if there's no Hp gain, there is a definate Torque increase. The car does pull harder in higher rpms without the resonator. Forgive my stupidity but i always though that allowing more air to flow into your intake easier would mean the pcm would adjust for more fuel automatically. More air + More Fuel = More power? without the resonator on there is an extra hole in the intake box to allow easier breathing of the intake. Thus, according to simple auto mechanics mathmatics...removing the resonator WOULD allow for more power..

then why have an intake at all? mind as well pop a cone filter on the end of the TB and call it a day. that would be the MAX air entering the engine with the least restriction. it would be hot air, but hell, that fartcan would cancel out the effects of the warmer engine

Removing the resonator does not give any power (if there is it's so minute that you can't even feel a difference), it make just makes more of a throaty sound.

Just leave the stock intake alone until you get a real (non ebay) intake. There's nothing to gain by messing with it.

just for your information...i dont have a fart can exhaust...my exhaust is still stock.

that's cause you're smart enough to know better

most of the idiots who try to rig up some sort of "free air" system instead of just spending 100-300 bucks on a good solid intake think the smallest things produce these hidden effects. the resonator is used to muffle sound, just like the exhaust resonator, nothing more, nothing less. removing it does nothing, as we've already said, and it's better to just spend the cash and get an intake that is built to produce more power, better acceleration etc.

I've been there, done that, years ago, and I know all it does is increase sound. Which makes sense since the resonator was designed to rid the car of the sound you are experiencing for people who want a quiet car.

If you think that removing that resonator gives you any noticable power increase, I would like to see what you say if you get a true cold air intake(filter in the bumper).

Ok, first of all I want to apologize if I came across as harsh before. I know a lot of people are giving you crap, and that doesn't help learning at all.

HP/torque:

you can't have an increase in torque without an increase in horsepower, because horsepower is calculated from torque. (hp=torque X RPM) You could have an increase in torque without an increase in peak horsepower, if the increase in torque were on the low end, for example. Peak horsepower for our engines is generally between 4-6k RPM, though, so an increase in torque in that RPM range would result in an increase in peak HP.

air & fuel:

you are assuming that because you have a more open air box, that you're getting more air into the engine. That may not be true, as the filter is probably the largest restriction. Even if more air makes it into the lower part of the air box, it's very possible that no more air is making it into the intake tubing than before. Even if it is, it could be a little warmer air, which contains less oxygen, which would offset any slight increase in air volume.

you are right that more air & fuel in general will mean more power, but it's dependent upon the correct air to fuel ratio. Too much or not enough fuel can mean power loss, and if the PCM can't adjust for the amount of oxygen (amount of air with temperature taken into account), then it can't get the A/F ratio close to the best mix (stoichiometric), and you can get power loss. That's why tuning is so important.


I'm not trying to be a jerk about this, but it is best that you understand that removing the resonator does not make a measurable difference in the power the car makes. It does make the car sound meaner, faster, and IMO better, though. And if you still think it made a notable difference in actual power, the only way you will prove anything is to do dyno runs with and without the resonator, and show a difference. Keep in mind, though, that the difference from one run to the next can be a couple horsepower, so even if you did a run both ways, it still wouldn't absolutely prove anything - it would have to be a repeated test showing a consistent difference.

It is probably just in your head. Kind of like when people change their oil and put the same kind in they always use and say it feels peppier. Just in your head.
