Thoughts on cat backs. Sound over function? Any before and after dynos?

Lol. How do you think more air gets through the filter? Those stock units do a pretty dang good job. They o ky way to increase flow is to remove eesistance in filter.

How is that accomplished?

Show proof that these after market filters do not allow more particulates. And marketing mumbo jumbo does count.

But just so those that don't know can find out. The main reason you get more air in isn't from the filter element. It's from the size of the tubing being larger, larger air filter element, and less restriction by removing all of the sound chambers that the manufacturers have to install to meet the federal imitations guild lines. Remember the old saying, fastest way from point a to point b is a straight line.

You can buy a cheap box filter for the oem air box and still get "more dirt" in the system. But the CAI/SRA systems themselves don't add any extra dirt. Unless you're buying the cheapest EBAY system and a cheap paper element, most name brand systems like K&A test their elements not just the pipe. This is why they guarantee them and why manufacturers use them.

Plan and simple, you are wrong.

That's got to be load in the cab. Which is fine when you step on it. But at regular speeds like around town and hwy, how does it affect the in cab music/talk volume? I like my flowmaster dual rears, but the bends are crap and it's just not the sound I want. So I'm thinking of going to a side exit.

Not intrusive at all when just cruising around etc. we have little ones and we use my truck more often than my wife’s CX-9.

One other idea is a full Dynamat install for the cab to keep the noise out.

You're the one giving our the wrong information. You prove it lets more dirt in. Seems you know more than those that make the engines, the vehicles, and the filters.

1. What does Ford or other OEM have to do with aftermarket parts??? Nothing. So points 1 and 2 are meaningless.

2. You belive people selling aftermarket parts marketing is factual? Lololol. Marketing folks love people like you.

3. There are numerous tests on-line that prove those aftermarket CAI filters let in more dirt. This is why you omitted links.
Actual test results are easy to find. Found these results in under 5 min.

"Comparing the AC Delco (rated the best from the test results) to the K&N: The AC Delco filter test ran for 60 minutes before reaching its max restriction while the K&N and AMSOIL filters each ran for about 24 minutes before reaching their max restriction. Another interesting bit of information is that the AC Delco accumulated 574 gms of dirt and passed only 0.4 gms. After only 24 minutes the K&N had accumulated 221 gms of dirt but passed 7.0 gms of dirt. Comparing the K&N to the AC Delco the K&N plugged up nearly 3 times faster, passed 18 times more dirt and captured 37% less dirt. The AC Delco filter which passed the smallest amount of dirt and had the highest dirt capacity and efficiency but also had the highest relative restriction to flow. Obviously the better filtering media is also the most restrictive".

And


That said, both the cotton gauze type (K&N) and foam filters (Amsoil & Jackson Racing) showed the same levels of filtration. Both performed poorly compared to the fiberous or paper filters (Napa, Baldwin, and Mazda).


But you keep believing commercials and people trying to sell stuff without question.

Filters vary a great deal in their quality, but consistently K & N's are near the bottom in terms of filtering efficiency.

AFE generally gets more air flow through a combo of 3 things that I've seen: 1) well designed air box and tubing, 2) much larger surface area filter, 3) offering several different levels of filtration varying from oiled (least efficient, most air flow) to dry (most efficient and very similar to stock but still having much more surface area, but less air flow than an equivalent sized oiled). The additional surface area is key.

A panel filter in the stock air box is usually not a good idea unless the pleats are much deeper, increasing surface area. Most don't.

Anecdotally speaking, my stepdad has a ranch truck that is a '99 Ford Powerstroke 7.3. I did some minor work a handful of times on this truck. It's had a K & N filter in the stock air box since it was essentially new and this filter was clearly allowing dust to enter the intake from the finger wipe test. This truck is also still running with 527K miles on the odometer and the original motor. It now needs ether to fire up in the morning but it was still a daily driver until over 500K miles. Point is that I wouldn't use a K & N, but in reality, the dirt they allow in is unlikely to ever make much difference in the real world for most people.

As far as Cat back exhaust systems go, I have no personal experience with them on this vehicle but plenty on other vehicles.

IME, even if the dyno doesn't show much, they really make the vehicle feel a fair bit more responsive.

Funny how you didn't post the link where you got that "test" info. That's okay though, neither did the user Crashmaster when he posted it to Acurazine. LMAO. Don't try posting other peoples "COMMENTS" off as test results.

Post the link to the site where a 3rd party tested the products. Do not post copies of other automotive forums and try to pass them off as test results.


For got to mention this. You asked what does Ford and others have to do with aftermarket parts?
You know what it does, but you choose not to acknowledge it. You know, Ford doesn't have a CAI for the F150. But yet they'll sell you one from Roush. And they'll even sell you an extended warranty. Now why would they do that if the CAI would damage the engine? I'm guessing Roush probably showed Ford their test results and Ford most likely did their own tests and came to the conclusion that hey, it does work!

Heres one for the K&N crap.

Oh I love me some test results!

So lets take a look at their numbers.

First thing you have to remember when dealing with tests like these is this is not and can not be compared to "real world" use results. As the tester stated " Temperature & humidity of the test dust and air used in the test are strictly monitored and controlled. As Arlen learned in attempting his own tests, there are many variables that can adversely affect filter test results. A small temperature change or a small change in humidity can cause the mass of a paper filter to change by several grams."

What this means is, if a person wanted to get the highest test results for a paper filter, all one would have to do is make sure the moisture in the air was low. Allowing for optimal moisture levels could give a benefit to one and not the others.

Also keep in mind we aren't talking about which filter is better for performance (power and efficiency). Per the tester, " The Flow Restriction response curves for each filter have the same basic shape. However, note how the AC Delco Filter, which passed the smallest amount of dirt and had the highest dirt capacity and efficiency, also had the highest relative restriction to flow. The less efficient filters correspondingly had less restriction to flow. This illustrates the apparent trade-offs between optimizing a filter for dirt capturing ability and maximum airflow."

In other words, the AC Delco sucked! From the very beginning of the test it flowed 4 times less air than the K&N air filter. This affects performance and fuel efficiency.

Per their numbers, The K&N filter flows almost 4 times the air from initial restriction, while only allowing 7 GRAMS of dust to pass through!

Now lets put that in to perspective here.

In a real world scenario, K&N says you can go 50k to 100k miles depending on the conditions. For my 2013 Chevy it's around 45k.

So per the test results, If the K&N hit it's max restriction rate at say 80,000 miles (seeing it flows almost 4 times more air) and the AC delco hits it's max at 45,000. Take that 7 GRAMS of dust and spread that out over the 80,000 MILES!!!!!!

Note, that it's IMPOSSIBLE to tell for sure (grams per mile) as some days will be dustier than others, but still 7 grams divided by 80,000 miles is .0000875 grams per mile!!!! OMG! YOU'RE GOING TO BLOW THAT ENGINE!!!! LMAO.

When people make statements like yours "you're just letting more dirt in", it's not being truthful.

You really know how to skew results to fit your opinion.

Ford Performance literally sells cold air filter upgrade kits for the 5.0. You increase surface area and pipe diameter, you get more air in at the same filtering efficiency with the same pleating per area. It’s not rocket science.

 

[tombf150]

I'm running the Corsa Sport and S&B intake on my 2022. It sounds great in my opinion although there are days I wish it was louder.

 

[missileboy]

Just to clear up the speed limiter assertions made earlier in the thread-

FORD Performance Gen5x 3.0L Stage 1 (you buy as part of the FP700 kit for the 21-24's), is speed limited to the Stock F150 limiter of 100mph
You can buy a Stage 1 update/cal file from Whipple that bumps the limiter to 135, but then you lose the warranty (3yr/36K miles)
If you get the Stage 1R (to upgrade your stage 1), that gets you 55lb injectors, a smaller pulley and a new tune/135mph limiter and about 40 hp (per Whipple's site)
If you buy your Stage 2 from Whipple then , that is a 135 limiter from the get go.
