Do AXLE BACKS Really Make POWER??? DYNO TESTING & MYTH BUSTING AWE EXHAUST

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.

[@antdiesel3]

Great video and series. Always nice to see someone taking a scientific approach rather than providing opinions based on feels.

[@ernestoduran5610]

Second great video of a dyno tune on axle back exhaust. And most people think it does nothing or even loose horsepower

[@gen13pinoy]

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 😅

[@ricardojcjr]

Awesome series! Aren’t 340i’s supposed to come with a base of 320hp?? Sorry if it’s a dumb question.

[@zacharytennant]

They test to the crank, this test is to the wheels

[@Anthony_G3027]

Was just thinking the same thing

[@92miata]

I think it’s due to 320hp measured at the engine but lower hp measured at the wheel.

[@dailydriven991]

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.

[@thejungatron6792]

Seems low for a stock b58 right? Cool nonetheless

[@JL-di2ut]

Yeahhh dang it’s low but it still feels fast to me I guess🙄

I know you dont sell them anymore but id love to see a downpipe tested. Catted and Uncatted.

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 👍🤓

[@_Forever555]

Awesome test, thank you. It gives us some perspective

[@SNeto67]

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.

[@dylan-nguyen]

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

[@robertalicea5585]

Can you do the same for a 9th gen V6 accord

[@Fluke2SS]

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.

[@piratehacker7025]

My 320xi has high flow downpipe, upgraded intercooler and stock muffler with stage 2 bootmod and im pushing 320hp.

[@nsflarna]

And here is why i prefer buying Bootmod3 through KiesMotorsports than through Protuningfreaks even though it's the same exact thing.... Trust

[@jhill92]

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.

is it possible to have a reduction in the initial acceleration by adding a freer flowing axle back exhaust?

[@mattcoppola]

Why is the horsepower on his 340 so low?

[@t.p1234xyz]

because factory HP/Torque numbers are at the crank not the wheels

[@davids6263]

@@t.p1234xyz 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.

[@Specter1031]

@@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

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

[@ACURACALABAR11]

I think to the wheel hp is different from to the crank hp. Marketing advertise the crank not the wheel

$1200 for a noise change and 8hp. no thanks. Glad to see yall are doing the dyno tests right! Love this series!

[@TheFanatic340]

I bought it for the noise change. The cables dp was for power. Love the sound

[@ErectileSceptile]

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

280hp? Isnt it too low? Dont bmw advertise this as 326hp if im not mistaken?

[@zacharytennant]

They claim that at the crank, not the wheels. This test is to the wheels

[@Inventi0ns]

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.

[@Nekahplz]

280 wheel horsepower to find crank HP which is what bmw advertises add +15%

[@lordgibbness]

At the wheels Vs crank I'd guess

[@mingyagi]

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.

Please do more videos for us reliable motor guys.
