I agree with a lot of the other comments I’ve read. The way you compared and transitioned all the clips and then did it quicker at the end so I didn’t forget what the last one sounded like… freaking perfect, thank you! Lol
Can’t decide if I should remove the spark arrestor or keep it in as the stock pipe doesn’t come with one and I ride MX/SX. Some say keep it in for back pressure and others say remove it to include PC?
Great comparison video! I installed a FMF Powercore 4 on my 21 YZ250F. Didn’t really make it any quieter, but got rid of that horrible raspy sound the stock muffler made.
It’s hard to go wrong with either, both are great quality pipes. I really liked the fmf, but in the end I thought the PC had a slightly better exhaust tone. Power wise I couldn’t tell a difference.
They are honestly both great systems but I definitely prefer the cleaner tone from the pro circuit. The fmf sounds great too just a little too much raspiness.
Nice comparison! YZ250F's are loud bikes - you think the PC is quieter than stock? Did you have the SA inserts in the FMF and PC pipes? The stock pipe performance is very good - did you find a noticeable improvement in the FMF or PC and if so which is best...FMF or PC?
Not sure it is quieter than stock with the insert out but definitely a much more enjoyable sound. With the insert it is quieter. I would like to get my hands on the ti6 pro, I think that would be the perfect combo for the bike. All three were very similar in power, pc felt a little smoother off the bottom than stock/fmf but no noticeable power gains with pc or fmf that I could tell, put them on a dyno and I’m sure there are some gains but I honestly couldn’t tell. I personally like the pc better solely because it has a much cleaner sound.
@@EnduroScum Thanks for the detailed reply. I've ridden a '22 YZ250F with stock and full FMF system and played with mapping. The stock system is very good and also very loud (raspy loud). Such a fun bike!
@@mxengineer1 the stock system is really good, I wouldn’t have switched if it wasn’t for the raspy sound. I really love the bike, what all mapping have you tried? I haven’t ventured too far off of the Yamaha map presets. Yamaha really did their homework! a friend just got the 22 crf250r and I want to ride it and compare. I see your videos of both and I don’t think you could go wrong with either one. You have some great videos, you get your hand on a lot of bikes!
@@EnduroScum I am fortunate to have friends that let me ride their bikes plus I have a few of my own! I like the "Hard Hitting" and "Keefer Free Flowing" maps on the '22 YZ250F as both make a nice change in character to the power - not big change but noticeable.
In person the pc has a cleaner sound, the FMF still sounds great but the pc has more of a high quality sound. Both are great pipes though and can’t go wrong with either.
@@motocam12 pro circuit to be has better build quality and sounds better than the FMF, but that is just my opinion. If you have the coin the pro circuit ti-6 pro sounds even better and not quite as loud.
I can’t really make a fair comparison since every bike/pipe combo are a little different. It’s been since 2014 since I’ve had a t-5 and those were dual shorty mufflers of my crf250r.
@@tylersvensson4468 it’s residue in the fmf from running leaded fuel from the guy I bought if from, hence the whitish gray tint vs blue smoke that oil burns. Thanks for your concern though.

Thanks!!
This is probably the best exhaust comparison on YT.. TY. 🙏
Thanks, glad it helped you out.
I like the FMF but that PC sounds really smooth!
Really can’t go wrong with either, I prefer the PC just for the cleaner sound. Both great pipes though.
@@EnduroScum just curious is there any way to get a spark arrestor on a PC pipe?
@@YamahaRider238 yes, they come with a spark arrestor.
Can’t decide if I should remove the spark arrestor or keep it in as the stock pipe doesn’t come with one and I ride MX/SX. Some say keep it in for back pressure and others say remove it to include PC?
The PC makes every bike sound like a kawi
Straight to the point and great job going back to back with comparison . I like the deeper sound from the Fmf. PC is cleaner though.
Pc definitely sounds the cleanest, find was pretty deep and throaty.
Best pipe video I’ve seen yet. Perfect
Thanks, I appreciate that.
Great comparison video! I installed a FMF Powercore 4 on my 21 YZ250F. Didn’t really make it any quieter, but got rid of that horrible raspy sound the stock muffler made.
Did you feel more power?
Pro Circuit sounds really good!
For sure, fmf is good, but the pc blows it away when comparing sound quality.
Great video
Thanks, glad you enjoyed!
FMF for life 😂 I want the whole track to hear me barkin😂🤘🏼🤘🏼
Haha! Nothing wrong with that!
I’m gonna have to say the fmf is my fav
It’s hard to go wrong with either, both are great quality pipes. I really liked the fmf, but in the end I thought the PC had a slightly better exhaust tone. Power wise I couldn’t tell a difference.
man I'm kinda partial to FMF but that pro circuit sounds wayyy too clean!!
They are honestly both great systems but I definitely prefer the cleaner tone from the pro circuit. The fmf sounds great too just a little too much raspiness.
I second that statement
The pc sounds meaner to me But the FMf has more of a growl But of you like
The normal snappy dirtbike sound i would go with the pc
Nice comparison video
Thanks!

As many people say, the stock muffler seems louder. (FMF sounds best imo
The Pro Circuit is a lot quieter, but the FMF sounds pretty cool.🤙🇺🇸
In person the pc has a cleaner sound, the FMF still sounds great but the pc has more of a high quality sound. Both are great pipes though and can’t go wrong with either.
@@EnduroScumwas the spark arrestor out of the pc
@@austinrocha7974 yes, that was without the sparky.
At this point it's really just "what looks best" as all the aftermarket exhaust sound the same.
Stock sounds really responsive
Stock is really good, a little raspy for my taste but power delivery/throttle response is good for stock compared to some other manufacturers
Stock suena excelente 🏍⚡️
how about a dyno test
@@4gclipseGT you foot the bill and I’ll have a dyno test done. There are places that have that info if you search.
Yamaha #1
I do love the Yamaha bikes!
Which one sounded the quietest in person? Kinda seems like the PC. Nice video seams
Pro circuit is slightly quieter and definitely has the cleaner sound imo
Which one would yall recommend
@@motocam12 pro circuit to be has better build quality and sounds better than the FMF, but that is just my opinion. If you have the coin the pro circuit ti-6 pro sounds even better and not quite as loud.
I don’t suppose you know the noise reading in the pc pipe?
I did not check the db levels on any of them, sorry.
Are these complete exhausts or just slip on?
In the comparison they are just the slip on mufflers.
Do you have to retune or re map a YZ250FX when you put on a slip on? I just bought a 2023 YZ250FX.
I run the keefer tune, so I had a different tune on before I put the exhaust on and did not change the tune.
@@EnduroScum hard hitting, aggressive or free flowing tune? I have all 3 on the phone app.
Are those just slip ons or full exhausts?
Yes, they are just slip ons in the video for comparison. I run the ti-6 full system normally though.
Is the pro circuit t5 louder than t6
I can’t really make a fair comparison since every bike/pipe combo are a little different. It’s been since 2014 since I’ve had a t-5 and those were dual shorty mufflers of my crf250r.
Pro curcuit
Pro c alot deeper
Yes, deeper and a cleaner sound than the fmf in my opinion.
Not a big difference 🤷🏻♂️
No, not a huge difference. The PC is a little cleaner sound than the fmf.
Performance difference?
@@jorgegama3848 a little more on the mid range power
pc pipe sounds best
Nice way to blow a motor revving it like that while still cold 😉👌🏻
Engine was operating temp, I cut the idle warm up time out. Didn’t figure people wanted to watch a bike idle for 5 min.
@@EnduroScum the bike was warmed the first time definitely not the second time lost about 50ml of oil in 6 seconds
@@tylersvensson4468 it’s residue in the fmf from running leaded fuel from the guy I bought if from, hence the whitish gray tint vs blue smoke that oil burns. Thanks for your concern though.
@@EnduroScum true
@@EnduroScum Always wanted to ask someone who has run leaded in a modern bike, do you ever get lead buildup on the valves or sparkplug?
Fmf exhaust sounds like it’s from the dollar store. All FMF exhaust systems sound like garbage.
I’m not the biggest FMF fan, I’ve always thought PC and Yoshi have a much cleaner sound
