help new cold air intake and exhaust

i just bought a new 2014 Tacoma TRD Sport with access cab and im looking to put a new exhaust and cold air intake on it. i know TRD makes its own intake but ive been told that K&N intakes are really good. i dont know much in the way of mechanical stuff so im not sure which would be better. the exhaust i found that i like is a flowmaster american thunder series cat back dual side exit part #817614. i think it would fit on the access cab but im not sure. i know i want a dual exhaust because i like how it looks other than that i dont have any real preferences . is this a good choice. any thoughts or suggestions would be appreciated.

 

K&N is pure garbage and the truck comes from the factory with a cold air intake. Use stock filters for your best performance. IMHO - Save your money for something that won't have negative impact on your truck.

After all I've read via Tacoma world. CAI intakes have had little to no effect of HP and fuel efficiency. More or less it's about the sound and the style. I must admit, I'm still interested but I've put it on the back burner for projects that will actually make a difference to my performance and HP. Good luck.

 

Don't knw how accurate it is...but aFe states a 13 HP gain with this CAI....

 

There are some great youtube vids on debunking car myths. One of which is CAI's. Look it up, easy to find, and use your own judgement.

 

TRD MAKES NOTHING. They contract out.

The old TRD intakes made by afe are great..... The new ones made by k&n are flawed and built on the wrong measurements.

K&n also flow great but lack in filtering.... U can do an oil analysis if ya want.


Many owners complain the flow masters fall apart from the inside quickly.... I agree, my 40 blew out rust.....

Chambered mufflers also are said to cost us HP.


Would u consider magnaflow, aeroturbine, or another non chambered?

Intakes.... Would u consider the afe stage 2 si?

 

Those making claims about intakes making no HP gains haven't seen the dyno proof over on xru..... Iirc there's some on here too.


The stock intake is made to be quiet.... To appease the masses.
This is done with baffles, chambers, silencers.... Whatever u wanna call them.

The afe stage 2 si, and urd tcai will yield dyno results.

 

Air filters alone do jack shit for us tho.

Gadget had his truck in controlled conditions on a dyno with the charcoal panel removed.....
Then with the regular air filter removed.......

He had no gains.


Then he removed BOTH those items......... ZERO GAINS.


run any filter u want... It won't increase HP any more than the acceptable differences in a back to back dyno.


When he developed his intake, he showed increased numbers..... Same with the afe.

Its a science.... Proper tube size, length, proper maf sensor distance and depth of mounting can make a huge difference

In my talks with him, he said he had access to some expensive testing equipment and went thru 7 or 8 versions of the urd intake before he found the right setup.

Rushing things doesn't make good products...... Just look at the new TRD (k&n rushed the prototype and used the 4 runner intake tube diameters as a reference). They spit out a finished product before afe did, and won the contract..... But again, its flawed.

 

Find one with the 1grfe?

 

Nicely put Justus Love the crowds who constantly claims the stock intake is a CAI already. I guess the stock air box sitting on the hot engine still makes it a CAI

 

I'm not picky about what exhaust or CAI I get but I do want a dual exhaust and from what I can find only flowmaster has one that fits the 2014. Same with the afe people keep posting about. Website says it fit 2012-2013 not 2014.

 

Just hang in there and do ALOT of thread research on here about any Mod youre interested in.....we all have made the mistake of rushing into a Mod only to find it won't work..or the wrong size etc. etc.....and welcome to TW..!

 

If you find 1 about the aFe...please post it.

 

^ This

Engineers work VERY hard on the intake systems of these to make sure they produce max HP, with minimal intake temp charges.

Unless you're building a turbo monster....don't bother.

 

I have a flowmaster 40 on my first gen and love it. I think the magnaflows dont sound as good as the flowmaster, but to each his own. The flowmasters are known to rob some low end power, and gain some top end, but minimal, nothing you'll feel. Personally I haven't heard a muffler that yet sounds good on the 4.0, but I don't think I have heard a Flow 40 on it yet

 

toyota pulls max power out of the factory?

I dont think so.

they have the engineers make the intake QUIET for the masses..... the silencers and baffles/chambers screw things up.

they keep the fuel mixtures rich for SAFETY also.....NOT max performance

these trucks cannot even carry their rated payload.

the engineers are pushed to make the trucks dependable, quiet, soft riding, and least of all extracting more performance out of the trucks.

why else would we have the USA trucks given a rear leaf TSB?

why else would TOYOTA hand out contracts to aftermarket manufacturers to improve on their designs?

really, the engineers CANNOT possibly be pushing that hard for performance on these trucks. Now, the sports cars Ill agree with.

when the supra came out they got down to the actual carpet fibers and finding the lightest possible carpeting to use.... now THATS where the performance is focused.... sports cars, not these trucks.

 

It's been proven quite a bit on this site that toyota was very good about getting all the power possible out of these trucks for the stock setup. Just throwing on an exhaust and a CAI does nothing, and that's been dyno proven. You have to tune it for the upgrades, and just about nothing short of some major change(supercharge, turbo, cams, heads, ex) does almost nothing on these trucks

 

not sure where u get ur information.........

http://www.tacomaworld.com/forum/performance-tuning/229882-n-power-gains-dynos-w-mods.html

the only thing u have proven is how much u have read inaccurate statements based on theories, and regurgitated it. People with uber high posts counts who THINK they know what is and is not a good product based on looks, or names tend to spew forth alot of this.... They are usually the same people running a bone stock truck and have never had the products they are dismissing, or have run a few items, and had bad results and become jaded and believe ALL like items are crap.

so, there is your proof in the link I posted for you, and if u would like more proof from actual people who DYNO their trucks, RACE their trucks on a track, made huge leaps for OTHERS by donating thier OWN time, money, parts, blood, sweat, and tears so that we may have the opportunity to purchase sleeves, rods, pistons, intake manifolds, intake manifold spacers, lightened pulleys, overdrive pulleys, and countless benched, dynoed, and patented performance products, I suggest looking on http://www.xr-underground.com/

or contacting one of the VERY few performance oriented folks who have been kind enough to come over from xru and shared their knowledge.

 

I'd love to see them and not from their company. I want third party tests.

Do you really think moving a filter 18" over will make a big difference? So silly. You guys are plain nutz.

Cold air intakes suck air from outside the engine bay.... filter placement is NOT whats makes something CAI.

So much drama over BS gains it makes me laugh out loud.

17 years ago when I was working my GT-40 crate 5.0 I put on a CAI made by combining a Kenne-Bell airbox, K&N cone filter, and running 4" diameter hose to my front foglight for ram air. THAT had REAL gains over the stock airbox sucking hot air from the engine bay.

Simply swapping the stock CAI for a aftermarket CAI and not doing any other tuning or mods will get you jack squat with a 4.slow
