Do AXLE BACKS Really Make POWER??? DYNO TESTING & MYTH BUSTING AWE EXHAUST
HTML-код
- Опубликовано: 5 авг 2020
- Hey Everyone,
Do axle backs really add any torque or horse power? In today's video we are DYNO testing the AWE Axle Back Exhaust for the F30 BMW 340i to either myth bust or prove power gains!

![AWE Catback Exhaust Install [BMW 340i]](/img/1.gif)
This series ROCKS! Straight up honesty goes a long way in the car community 👍🏼
Great video guys ! Awesome job by Chris and Bryan !
Awesome test, thank you. It gives us some perspective
Damn you guys always get me pumped to mod my F30! Most of your myth busts so far had the expected outcome but it's really nice to have some data from cars similar to your own.
I literally just had AWE axleback exhaust (w/black diamond tips just like yours), installed today 08/06 at Speedlogic in Fullerton. Cars is a 15' 435i xdrive GC. Car was already 400hp. It certainly felt a little faster. Now you have proved my butt dyno was correct. Great relevant content as usual.
Thanks for keeping it honest guys.👍👍
idk how but you guys make interesting bmw content that is both more informative and more wholesome than other channels. thanks a ton, from someone with a g20 who is still addicted to your f series content.
Great video and series. Always nice to see someone taking a scientific approach rather than providing opinions based on feels.
Love the vids !!!
Awesome iv been waiting to see some results and dyno runs for the gen 1 b58
Awesome content!
Great video!
Great video. Maybe a video on how the dyno works and how it's setup might be beneficial. Might take care of some of the confusion in the numbers measured/expected 👍🤓
Chris seems like a jolly cool fella, nice video guys...
This testing series is awesome. I have the AWE axleback but am considering the midpipe as well for just a little more volume. No DP plans. I wonder if the AWE midpipe will add any more power on the dyno.
Nice video!
Second great video of a dyno tune on axle back exhaust. And most people think it does nothing or even loose horsepower
What about a muffler delete altogether? I’d like to see that one 👍🏼
It makes a difference on turbo cars
And straight pipe
Me too, been thinking about doing muffler delete for years but don’t want to sacrifice reliability
@@samflora7227 no car should break down with a muffler or a resonator delete...
@@samflora7227 lol
Solid gains for just a muffler! I wish I could upgrade my exhaust.
Btw the stealth microphone setup is on point lol
😂😂😂
Why can’t you? Local bylaws?
@@fabulousprofound i think thats sarcasm....hes changed it like 6? times hahaha
Thanks!
Thanks!!
The dynapack at AutoTalent in LA generally runs the same as a Mustang Dyno.
I miss these videos and Chris! RiP brother
Brian please dyno f30 n20/26 bm3 stage 1 with stock dp? Seriously f30post forum doesn't have a single dyno of bm3 stage 1 gain. I 😅
Makes me feel good my 2011 335 xdrive made 270 whhp bone stock
Agreeded with Stephen Lozano yal should do a cat/res/muffler delete an see what kinda numbers are put out
Is the stock axle back exhaust for sale ? I am local
Great video overall
Hi Brian, how's that f30 spacer video coming along? 😆
Could you please dyno test bootmod3?
Green and red truckers , getting some Mario and Luigi vibes here
Any videos on a G20 330i tests
I can save you almost 7 minutes. The answer is Yes. That said appreciate the testing done. I do have full exhaust all I need is the axle back to finish it.
Chris a cool dude
No kap
My 320xi has high flow downpipe, upgraded intercooler and stock muffler with stage 2 bootmod and im pushing 320hp.
Can you do the same for a 9th gen V6 accord
I have a Remus on my bimmer and thats how much the company was claiming on the gains.
Hey guys love the channel very in informative, I would love to see a video comparing botmod, bummer code, and xhpflashtool what do they allow you to do for your bmw, what can or can't you use if your car is still stock, which is or will be a better option for us with no upgrades or which upgrades do you need to have in order to use the correct flash, there are a lot of questions I have because I'm not a car guy so I'm uncertain and uncomfortable with investing in one of these flash tools, and also I really want to go from and to red with the xhp but do I need to only purchase the rwd license and I can flash it or do I need to get the license and then purchase the rwd package? I need the help please.
Steven N55 bm3 is for hp/torque flash tune
Bimmercode is to code car features or remove
Xhpflash is for a transmission flash tune
They don’t really overlap. Only thing that does bm3 has a tranny flash tune for some cars.
If you want power bm3 is the only one that will give it to you. And probably the best money spent
Would you see similar numbers for an f32 n26 engine that’s tuned stage 1
would engine heat soak not play a part to " lower " gains by the time the 6th run is done ... ?
is it possible to have a reduction in the initial acceleration by adding a freer flowing axle back exhaust?
I know you dont sell them anymore but id love to see a downpipe tested. Catted and Uncatted.
That would be a lot of work though. But yeah that would be very interesting.
Anyone know why they stopped selling them?
what about the deverter valve myth busting, stock vs gfb vs turbosmart
Kies: makes good content for my F83 and me
Also Kies: gets a dyno
Kies again: makes even better content
Keep it up guys.
And here is why i prefer buying Bootmod3 through KiesMotorsports than through Protuningfreaks even though it's the same exact thing.... Trust
I need to see bootmod3 results
Pleeeeease test a downpipe in an f30 🙏🏽
Why is the horsepower on his 340 so low?
because factory HP/Torque numbers are at the crank not the wheels
@@toddpope2134 doesn't matter. It's been proven multiple times that the b58 is under rated by bmw. Most dynos show 330~ hp at the wheels. Theres something wrong with this particular engine.
@@davids6263 perhaps loss due to awd? I think the dynos charts are usually for rwd. Or maybe this dyno is calibrated really (I mean REALLY) conservative
I clicked link for muffler to buy and it has an error on landing page
Awesome series! Aren’t 340i’s supposed to come with a base of 320hp?? Sorry if it’s a dumb question.
They test to the crank, this test is to the wheels
Was just thinking the same thing
I think it’s due to 320hp measured at the engine but lower hp measured at the wheel.
What! That seems like n55s number to the wheel. I thought I would get 300 at least. You think its because x drive? But, still an insane engine. Just wished I had that that or n55
Some Ewg N55s make more than this
That’s weird amount of HP for the 340 I had mine on a dynojet stock it made 303-305 whp I’m xdrive too
Hold on I’m lost a 340i is making ONLY 277 horse power to the wheels that’s desapointing can someone please explain why a 365 horse power when down to only 277 horse power
RIP Chris
Don't you think larger fans are needed to feed the engine the proper rate of air flow? I see dynos with tiny fans in front and other with massive fans.
$1200 for a noise change and 8hp. no thanks. Glad to see yall are doing the dyno tests right! Love this series!
I bought it for the noise change. The cables dp was for power. Love the sound
Noise change is absolutely worth it, cars are so quiet these days. Also 8 hp is nothing to scoff at, it adds up. Could be the difference between 295-ish whp and breaching that 300 whp barrier.
It's literally one of the power easiest mods you can do for a turbo car
@@TheFanatic340 Same here. bought it for noise but if it can add hp then its a plus..
BMW exhaust too expensive, should’ve bought a Honda
@@jeff8062 pay to play if you don’t got money then don’t buy it
I've seen over forums and other videos stock 340 doing 320 to the wheels so what is going on here???
American dynos are pretty weird. Our numbers are definitely inflated lol
So M perfomance exhaust adds power🤔
BRYAN, PLEASE MAKE THE F30 SPACERS VIDEO!!!!! PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE 🙏
Seems low for a stock b58 right? Cool nonetheless
Yeahhh dang it’s low but it still feels fast to me I guess🙄
The b58 in my X3 is making 382hp from the factory.
Its the all wheel drive
TheFanatic no lol it’s because it’s the wheel house not crank as advertised on commercials
@@anthonypipia6990 there is more drive line loss on awd as opposed to rwd
I thought a 340 made 320hp stock ???
I think to the wheel hp is different from to the crank hp. Marketing advertise the crank not the wheel
this is to the wheels, its 320 hp to the crank
No chance this is a 340i
277hp that very strange for a 340i normaly the 340i have ~326hp can you respond me why he have so low hp?? @kiesmotorsport
How is this 340 not hitting 300-325hp?
That’s what I’m saying my stock 2015 335 dyno’d in at 308 wheel
Mario and Luigi
280hp? Isnt it too low? Dont bmw advertise this as 326hp if im not mistaken?
They claim that at the crank, not the wheels. This test is to the wheels
Yeah sounded low to me too. BMW claims the 340i comes with 320hp but that's at the crank. I was surprised though because I've heard claims that BMW underrated the car and it was actually making close to 320 at the wheels.
280 wheel horsepower to find crank HP which is what bmw advertises add +15%
At the wheels Vs crank I'd guess
326hp is supposed to be at the crank. The 280hp measured in the video is at the wheels. Measuring at the wheels will factor in drivetrain losses etc.
Do you not sell anything for an e92 n52 328i? You NEVER do any videos for them. I get it that not as many people modify those engines, cause it’s not as easy to gain power from those motors, but there are tons of us guys out here who still wanna modify our cars. Please do more videos for us reliable motor guys.
If you could do the intake next, along with the axel back (stock tune) that would be awesome! Think a lot of people get these two parts first (I did).
edit: Chris is so cute no homo
You got a boost leak or something, too low
