aFe Equal Length Catless Downpipes Sound Testing and Review

- NOTE: Most Ford shops will not service your vehicle without catalytic converters. I recommend getting the catted equal length downpipes so you won't have this issue nor the CEL.
From talking to numerous engineers the catted will yield slightly more torque while the catless will yield slightly more horsepower.

Great job on this. the detail was spot in your review was great
I have the atak, super quiet when cruising you can barely tell it’s aftermarket but it’s super deep and gets really loud when you get over 4000rpm. Couldn’t be happier
Man I just discovered this! How are you the only person that seems to have these? More people need to know about these equal length pipes!
Same here!
These downpipes were taken off the market by the government. If you can get measurements a muffler shop can recreate it.
@@Attemptingtospare SPD makes an Equal length midpipe now that is much easier to install and has the same effect.
@@OnlyDigs ya the trombone resonator delete
@@Attemptingtospare Yessir, I was the first one to test one on a non raptor F150. My truck is in a lot of SPDs advertisement videos.
Sounds so much better with equal length downpipes, smooths out sound
Sounds so god damn beastly!! 🔥🔥
How low does the EL loop hang? Thinking about adding one but worried it will stick out too far
Great video! Thanks for taking the time to put this together. I have the same system except I have the SPD catted downpipe. No check engine light with SPD catted downpipes, and more RTQ with cats vs straight piped. The cats also help take out the rasp, however the X-pipe is what really causes the worst rasp, especially going catless. What tune you running? I currently have the AFE Scorcher Blue and love it.
I use the aFe Scorcher Pro. Only go this route if you're willing to risk sacrificing your warranty or if you have an amazing dealer that doesn't immediately penalize you. They send custom tunes based on all the parts you have in the truck. Although once I get a turbo compressor wheel upgrade I'll likely be taking it to a local shop.
And yeah I actually am going to go catted equal length in the future. Catless has more HP, catted has more TQ from the engineers I spoke to. I use aFe because they're the only ones with an equal length design which further helps performance.
With the catted downpipes, do you get backfiring? That's the one thing I found lacking with the setup in the video. I mean the raptors hate to backfire, very rare, which is generally a good sign about a tune; but just curious if you get more pops~
@@geezernyounggun5136 When you say pops, do you mean detonation? I had my truck go into limp mode one when I was street racing, other than that no issues. I'm really looking forward to what COBB Racing is about to release!
Michael - can you describe the circumstances that put your truck into reduced power mode? Tune you were running, fuel octane level, engine temp, transmission temp, ambient air temp. I ask this, because mine did it several times, traced it back to the transmission needing an update flash. Never had an issue since.
@@geezernyounggun5136 I have the AFE Scorcher Blue, the one time it went into limp mode I had been driving normal, booted it off a light, and lost power at high rpm in 3rd gear. The code was a misfire issue, and never happened again since.
Michael - that was the same scenario mine decided to not shift out of 5th, then once on 7th, then on 3rd. My codes were misfires as well. As soon as I shut the truck off and restarted all was well. The frequency started getting closer together and more often I thought it might be the tune, so I set it back to stock. I was in town when I took off from a light it was still in third, gear and didn’t shift and went into limp when I pressed the accelerator to get up a hill. I took it straight to the dealer, the code was misfire, limp mode kicked in because the engine was under load in the wrong gear going up the hill. All that was needed was a transmission update. So just a nugget here, if it starts happening more frequently, you may need to have the transmission control module flash updated.
Thanks for posting. Super informative video. I'm curious how you got the coolant temp to read an actual degree value? I have a 2019 Limited with the HO 3.5 so maybe thats the difference.
Raptor has h.o 3.5 aswell, but nice brag attempt
Forscan. It will let me make a ton of changes to the truck, like coolant and trans temp above the gauges, lighting options, etc.
Limited can get the H.O. as well, only limited and Platinum F150s from 2018 or 2019 and newer.
Yep as OneOneNineFilms said, Forscan is the way to go!
What branch of service?
lmaoo i was like wtf i think ive seen this raptor around before.... turns out you live 10 minutes away from me LOL....i was like if this is home depot this is definitely the same one... truck sounds awesome man! i was looking into truck options for my daily as my genesis is totally impractical especially during inclimate weather ... i was looking into the new 2019 ram 1500's and also raptors and it just so happens i came across this video
Haha very cool - We should meet up sometime haha. Home Depot is like another home to me lol.
And definitely go for a Raptor if you can. The 2019's new shocks, wheels, and Recaro seats (option) along with terrain control system etc are insane. Definitely go for a Raptor. A ram can't compete in any which way lol
what year is your raptor?
Hi, thanks for the vid, great quality, I have a 2017 platinum f150 eco boost, wanted to do some exhaust work for some hp/tq gains, that being spd adapters, spd 3” catted down pipe... my goal is to as much as possible maintain the trucks current quite bark, but confused to whether even do the down pipes if I’m not increasing bore size on resonator section and muffler back to tailpipe, I know spd has a 3” performance resonator kit, but then the next bottle neck is the muffler, anyways correct me if I’m wrong but basically wondering if doing the adapters and downpipes but leaving the rest back of that stock hinders any gains.... and if it would then what would be your recommended set up from resonator to tailpipe to keep her quite...regards
Kyle - Don’t worry about the bore size. If you go with equal length catted downpipes you will gain bottom end torque but lose a bit of top end speed. The opposite is true for catless downpipes. The cats will reduce the bark and will be fine with the resonator, and still sound good. If you do the equal length performance catted DPs, don’t waste your money on SPD. That is really a cheap means of getting minor gains for a stock system. aFe has the equal length catted down pipes.
I'd like to go a bit further with your truck so I can share better recommendations (Alex here). Which engine are you running? 2.7 EcoBoost, 3.5 EcoBoost, or 5.0L? Makes a difference in terms of exhaust setup.
Quick question I dont know if you can help out in this or anyone reading this. I installed the 3" SPD resonator delete and the Corsa db exhaust recently. I want to install the 3" SPD downpipes with the turbo adapters too but someone told me that the turbos would get "lazy" in low rpms because the 3" pipes were suppose to work the turbos at higher rpms. Something to do with proper back pressure. Is this true or can someone enlighten me on this lol my bad I'm not a gearhead.
Jorge - It isn’t that they get lazy, but they don’t operate efficiently. If you go with performance DPs, you are really tossing about $150 away for minimal gains by adding the spacers. The only issue with back pressure, is running an “open” exhaust or very low restricted mufflers, then back pressure is reduced and it will be greatly inefficient. Back pressure is needed, but it is a fine balance between too much and not enough. The 3” pipes are what is stock diameters, so that isn’t a problem. I highly recommend equal length catted downpipes because you will gain low end torque, but trade off for top end speed, which isn’t important in a 4x4. Turbos usually don’t spool at low RPMs, because boost isn’t needed, until you need more RPM and power, then they will spool up and provide boost, once they reach the right RPM and speed, the turbos stop producing boost and the engine is running under its own unboosted power. If you are driving down the highway and have “rolling” gradual rises and falls on that stretch of highway, as you ascend a rise, your boost pressure might reach 3-5 psi to maintain your speed, but when you come down the other side, the boost drops out. Does this make sense? Basically, turbos are only operating at boost when added power is needed. If not, they spool down until you need more power... the unneeded residual boosted pressure is then released through the blow off valve located at the intercooler.
Driveway engineering is great. Just do it.
Thanks for the informative video. I like the way it sounds.
I am running basically the same system, except I have Stainless Works downpipes with high flow cats. I had to put spark plug extenders on the O2 sensors to keep it from throwing a code. Were you able to get around throwing a code, without cats?
Nope.. after about 50mi I get the code. No issue to have it, just a warning, but I'm going to try to find a way with extenders and the like to get the code to go away, just one less thing to look at lol
You have a $60k truck... just get a $500 tune
Ehh this is 3 years old, my B
Okay so I have a 18 raptor with just the borla atak on it how do I get the turbo whistle through the exhaust?
Interesting, but this is exactly how I thought it would sound (and what ford now seems to be addressing on the new raptor). The Unequal length headers give V6's the classic "work truck" uneven sound, the sound that is pretty much universally disliked, unlike the "smooth" even sound that you'd expect to hear from a high performance V6, for example a 370z. I personally think either header setup sounds pretty sweet. Never understood all the flack about the sound, it doesn't have the mean "American Muscle" V8 sound, but you do get cool turbo noises too so in my mind that makes up for it. I guess that's the ricer boy in me that doesn't care how it sounds as long as it's turbo'd, lol.
Always wondered why ford went with unequal length headers on the ecoboost trucks, EL headers seem like such an obvious move. Most people unanimously agree that EL headers sound better on 6 cylinders. Subaru's, not so much lol.
Yeah the burble from keeping unequal length on an STI sounds WAY better
Catless downpipes still can get P0420-P0430
Do you like the exhaust smell without the cats?
love the smell lol

How do you shut off the cats so you don’t get a check light?
brent - You don’t want to take the O2 sensors out of the mix, how Ford sensor lines work in a daisy chain configuration, up and down the electrical stream. If something is missing that another sensor in that stream is relying on for information, that will trip a series of other CEL/MIL. Then it becomes a game of chase down the sensor, when there isn’t anything wrong with it at first, but could malfunction in the future. Also o2 sensors are important for engine operation, not just to keep the environment happy. They determine if the exhaust entering and leaving the catalytic converters is running rich or lean, which in turn tells the PCM to increase or decease the air/fuel ratio. Just get the spacers for the o2 sensors and that will eliminate your CEL issue, and ensure your engine is performing optimally.
@@geezernyounggun5136 right, u can use o2 sensor spacer without tuner. and i planned delete cats on my 2012 F150 today
What year is your truck?
2017!
If you're over 3500 miles you may want to check your oil pan gasket mine has 3400 miles and it's already leaking
At 18000 or whatever and not cracked yet, but apparently there is an aluminum one now... I'll be asking the service department about it for swapping the damn plastic one for the metal.
How do you not have CEL ?? Tuner ??
He does lol
Are u still getting rid of stock exhaust and how much ?
Asking to buy the stock exhaust set? If so feel free to shoot me what you feel is a fair price (Instagram DM: nj_raptor)
So...this is what Ford is doing on gen 3 right?
Yep! Basically. Though the "trombone loop" is after the muffler which I find to be strange still... But better than not!
Not sure why all F150 Ecoboost vehicles don't have the equal length downpipes. It really is the secret sauce to avoiding that horrible sound at higher RPM with stock length downpipes.
It's so it's quiet from the factory and to fool some into thinking it's a v8
Just like Subarus equal lengths make the sound Soooo much better!
Probably easier to just slap the Borla Atak mid section assembly.
Yes, but you don’t get the extra performance; also the sound is more raspy, less deep, and less turbo noise. You will get louder crackles though, that's what I miss about adding the resonator.
“Basass”
yuk!!! I have an eco boost too and exhaust sounds isnt their strong point!!
I guess you don't live in Florida. Sounds like what we call a ricer . Honestly but the stock stuff back on. You can make 12.80's with a tune, intake , downpipe and other little things and YES STOCK EXHAUST!!!!!
I live in Florida and I have the ATAK exhaust which is much louder and a bit deeper, sounds nothing like a ricer but ok 😂
This sounds nothing like a ricer. The problem is most exhaust companies try (and fail) to make the ecoboost sound like a V8, understandably so, because that's what most stubborn truck owners want. This exhaust sounds like a high performance V6 should, similar to the Ford GT or a GTR. Also, these trucks (including the regular f150 3.5 ecoboosts) can run much faster than that with some simple fueling system upgrades and E85 tuning. It's not hard to make 600whp and get these trucks into the mid 11s for under $3k.
