2024 KX450 Pro Circuit Vs. Akrapovic Muffler Shootout 

Really appreciate your effort in making more YT videos. Listen to all of your podcasts religiously, without a doubt I am able to better understand what you’re explaining in these videos than the podcasts. Please keep them coming !!!!!

This is the morning content I needed.

Both beautiful pipes.

Been waiting for this to help make my decision thanks!

Great review Keefer

Great video!!!

I wish I wasn't as impatient as I am, I paid $10K OTD back in February 🤦‍♂ And then spent wayyyyy too much for the aftermarket goodies. But, oh well, I love it!

TI 6 vs FMF 4.1 mega bomb is what I’m interested in!

Good video Keefer, Do you have any more 2024.5 SXF 450 FR Content coming?

Eddie’s thumbnail looks sick!

Keefer you’re the man. Love these vids you’re doing. Maybe test some Luxon clamps next? 😬

The Pro Circuit Slip On is also a better option over stock. Good for the weekend warrior.

have you tried the get sx1 ecu

Omg I had a 2004 kx450F. And I miss riding so much. But I’m to poor lol and have children. Maybe someday I can again.

Dirt bike / off-road magazines take note of this channel. Simply great concise, to the point content with no annoyingly loud music intro...

Paid $7398 out the door for my 24 kx450.Leaves plenty of room for after market exhaust

FMF is even better. The FMF full ti pipe or the FMF slip on with stock header is also better than the Pro Circuit.

Where to buy the pro circuit exhausts? Everywhere appears backorder only

Thank you for this... I have your map in my 24 KX450.. Do you still use your map or you using a Vortec still? I have done the FREE MODS, exhaust,and airbox,and Keefer Map.. love the bike

I like the Akrapovic exhausts on my street bikes, but for my dirtbikes, i prefer the Pro Circuit. It sounds much better too...

Pro circuit sounds good

Keefer is the twin air power kit worth the coin vs just running a 3d printed cage with twin air filter?

Hi guys. You firmly suggest not to remove the spark arrestor from the Akrapovic cause it affects the bottom… Do you suggest the same thing with 250s?? I just bought a 2025 sxf 250 Adamo replica that comes with an Akrapovic muffler and immediately removed that final reduction….and it seems to me that the bike is quite empty down low…. Thank you

If you put higher quality packing in the muffler, like those pillow packing rolls, doesn't that fix the problem with the Pro Circuit?

2 things. 1. I saw you doing this yesterday at GH and it's already up on your channel. Amazing. 2. Were you wearing a vest to be hotter for LL prep?

Great video dude, but we need to get away from this "back pressure is good" idea. That was a salesman keyword that has no place in the real world. It's dyno and track proven that back pressure in a 4 stroke exhaust only hurts performance and power. Let the 1960s marketing fable die.

The price of these exhausts is getting out of hand. Cost of production of these things is no more than $200. I think the consumers are just flipping the bill for the race teams that use this exhausts for free as they’re sponsored by the brand.

$1700 for an exhaust system is Ludacris, I’m sure it’s nice but bro. a full system for a 2 stroke is $400.

$6k or $7k? Huh

The KXs are pigs now. At least it saves weight
