Black Tip Exhaust

Oh man, here we go again.

 

In my opinion no. Its a V6 and I hate that bubble bee sound the v6 and 4 bangers put out with exhaust. The TRD exhaust has a very nice sporty tone to it. When its cold you'd barely notice it, but once it heats up its got good clean tone to it. When you put it on the floor, you here the intake more than the exhaust. I put the intake on before the exhaust. The TRD Intake alone with stock exhaust made a HUGE IMPROVEMENT. The sound changed drastically. If I would have done them both at the same time I would have thought the exhaust was making all the noise.

Hope that makes sense lol

 

I'm sorry, did you have something you'd like to add to that or a comment???

 

Yes. We've been down this conversation many, many times. You didn't add any power. Z E R O. Your butt dyno is just feeling the smooth vibrations of the exhaust note in your crack making you think you're going faster. You aren't. At all.

You added noise. No go fast juice. No "freed up some air flow" or "smoothed out the torque band".

Let's just cut this long conversation down right now. You like the way it sounds. So do we.

 

Cool.... btw could you share a link or something to this information showing where someone with a 17 Tacoma did the dyno and had zero gains in HP and torque VS the stock intake and exhaust? I'm very intrigued by this.

I find it extremely doubtful, but if you have real results please do share.

As there is obviously a lot of debate about whether or not installing a cold air intake is worth it, they do improve efficiency, and therefore must add some power over stock. The cold air intake increases efficiency in a few different ways. First, they remove all of the sound baffling in the stock intake, which this baffling is restrictive, and it’s only purpose is to reduce the noise of the engine at wide open throttle. Hits the reason i mentioned the sound difference after install above. Second, cold air intakes collect air from outside the engine compartment (where air temps are notably higher). Cooler air is more dense, which means there is more oxygen in a given volume of air…and more oxygen means you can burn more fuel. So with that in mind.....depending on your setup, installing a cold air intake can add some horsepower, and slightly more torque.
In almost all instances as a bonus, cold air intakes also improve throttle responsiveness, and many truck owners report improved fuel economy after installing an aftermarket intake.

In regards to exhaust. In addition to gaining an awesome exhaust tone. Much like the factory air intake, the factory mufflers are designed to be quiet first and efficient second. If you replace the quiet factory muffler with a quality after-market unit, you’ll see a slight increase in horsepower and enjoy a hearty exhaust tone. If you replace the factory exhaust system with an after-market tuned cat-back exhaust, you may see gains from 5 horsepower to as much as 20 horsepower (depending on the size of your truck’s engine).

Finally, if you replace the factory exhaust manifold with a set of after-market headers, you can pick up a few more horsepower…just make sure you understand that changing your factory exhaust manifold can change your truck’s torque curve. Long-tube headers, for example, often increase horsepower at the expense of some low-end grunt.

So for you to say "You didn't add any power. Z E R O. Your butt dyno is just feeling the smooth vibrations of the exhaust note in your crack making you think you're going faster." which is just a very ignorant way of saying you don't have a clue what you're actually talking about.

Bottom line is, I answered a members question with my opinion and no one said "Hey fuckstick Freetime" whats your input?

 

Your factory intake is a cold air intake. It's not drawn from the engine compartment. So no, you didn't add any HP there. You gained an intake note from the changed filter material.
Contrary to what you've said, most members here report worse mileage after installing intakes/exhaust. Whether from the installed equipment or their changed driving habits, we don't know.
You can install all the exhaust and headers you want. This isn't a 1970's NA/carbureted motor that benefits from bigger/smoother pipes in/out. This has been rehashed over and over here and on many other forums. You aren't changing anything in your performance for the better until you change the tune of the motor. Often, without the tune, you've made things worse.

As a side note, I didn't call anyone names. So, Brett, you can keep your stick for whatever you use it for. Texas is a weird state. Keep it over there, thanks.

 

And your saying Florida is LMFAO I'm going to excuse myself now.

 

im here for the popcorn

 

I've been a member here for 7 years, and I can tell you very few people will back what you are trying to say. Other than headers, those have been proven to give a little gain, but like you said, sacrificing lower end.

 

Careful of the wording. Even K&N says "up to x hp" which does include none. The sensors and ECU do a pretty good job of keeping shit stable and has been proven many times that for the tacomas CAI and cat backs don't do anything but change noise and take away low end. These are not WRX...

 

I don't actually know if those two add-ons will give you any extra power on their own.. What I do know is OVtune does, and there are dyno results to back that up.

Edit: The latest tune incorporates significant changes to ignition/fuel injection/VVT etc etc etc.. and that gave us appox 10% peak HP improvement (and a nice torque bump from 2000rpm on up). Now that you can feel!

 

A good friend of mine owns a performance shop here in the Houston area and has a Dyno and another friend/colleague owns D3 Performance here in the Houston area who also has a Dyno. I'm now going to see if they have time to do a quick run with mine to see if there are any gains. If I get the chance I will post the results here.

 

Nice!

Now, of course you'd have to put your truck back to stock, do a pull or two, install the upgraded intake/exhaust and do another couple of pulls to really see the difference. Too many variables otherwise I would think.

Anyway, have fun and good luck

 

Well this got out of topic quickly. I used to have a aftermarket black metal mulisha tip and it rotted away after a year just from the rain.

 

I've got a friend that works for Toyota mechanics plus ill do some research. I am going to see if he can pull an accurate number for a 17 Tacoma TRD Sport DCSB stock. If the Dyno numbers an even close no matter lower or higher then there are no gains. If its at least 10 points higher though then we know there are some gains.

 

Black out package?


They need to black out your bumper...

 

Actually, that won't work. There are way too many variables between natural, vehicle, and dyno settings, even with the same model dyno. You really would need to put it back to stock, or at the very least find another TRD Sport to run back to back with your own.

 

Looks good.
