Two Brothers P1X Power Tip Videos

Two Brothers P1X Power Tip

Many municipalities and tracks have begun to implement new, tougher regulations that limit the sound output of street bikes, offroad cycles and ATVs. Two Brothers Racing has developed a series of highly effective sound reducing tips which can help you be compliant.

Two Bros' P1X PowerTip sound suppressor is a recommended accessory for our exhaust systems with M or S1R series endcaps. A straight-through sound diffuser, the TBR PowerTip quiets the pipe about 7-8 dB with no significant reduction in horsepower. May be used with a spark arrester screen.

Easy to install - simply unbolt your existing M or S1R series endcap, drop in the P1X and reassemble.

P1 Power Tip also available for 3-4 dB of sound suppression.

Get This If You Want To Tone It Down
The P1x was DEFINITELY WORTH IT and I give it 2 thumbs up. The ride was much more tolerable and with the clutch pulled in, I was almost ninja-like. Once I got back from my ride, I decided to test the actual noise level to see if it the P1x actually helped or if it was all in my head like Derulo. The sound isn't as nice, sounds like it's getting choked by Royce Gracie, quite baffled but still more distinct than stock. The only thing I kept a bit lower is the price. Yea, $30 isn't bad considering the slip on is well over $400 but you would think something like $20 would be suffice for a product like this. Final Verdict: GET IT if your 2 Brothers is too loud for your liking

Does what is says
Bought these for Two Bros M2s on my FJR. There is a significant noise reduction. Before the P1X tips the exhaust sound was great, but loud and even caused buzzing in my ears. Now it is still great sounding, especially compared to stock, but much better for me and my neighbors. Also received the shipment on the next day. Very satisfied.

Huge improvement.
I bought the 2 bros system for my 2013 Ninja 650 and it came with the P1 tip (not P1X) as default. I know most people say to buy a juice box/power commander fuel controller at the same time, but I didn't. The stock bike was far too silent so I wanted a bit more sound, but with the P1 tip it was just excessive. People would give me dirty looks and I didn't blame them. I was also getting a lot of backfires, which is probably due to the lack of a fuel controller. Also, the power gains were pretty much non-existent. It felt like it just got louder when I pulled the throttle, and as a result of my desire not to be a jerk to everyone, I rode around gingerly. Perhaps there was more power at 7000 rpm +, but that loss of midrange made the throttle response feel terrible.

So with all these dilemmas, who would have thought that a little bit bigger of an exhaust tip would make such a difference?

The sound, first of all, is great. It's at a more reasonable level, but it sounds powerful instead of just obnoxious.

The backfiring has almost completely stopped, and now it's just a tiny pop now and then when I close the throttle going down hill.

And the power.. the throttle response is back to what it was, and then some. Maybe I lost 1hp at 9999 rpm or something, but I'll take it in a heartbeat.

I can only speak for my bike, and maybe it's all about the fuel controller, but this has changed my feelings on the exhaust system from regret to excitement. And such a small change, physically...

Amazing difference!
I just bought a cbr600rr that had its catalytic converter cut out and two brothers exhaust installed. This bike is obnoxiously loud and I always came off the bike with a ringing in my ear. I went on a few rides with the power tip installed. What a difference! Now I'm not suffering from ear ache and it still sounds beastly!

Worth it!
Worth every penny! In my opinion it was worth the price and helped tone the sound down around my neighborhood and made it easier to ride not to disturb to many of the neighbors around me. Easy installment only reason it didnt get exactly perfect score was because I really didnt feel a performance difference, other then that I back this product up 100 percent and if youre wanting that same deep sound without makin others mad and still be noticed this is for you! Revilla really delivered this asap with no problem alot more orders in the future they have my buisness!

Less backfiring, less noise
The tip was a bit of a pain to get in on my bike since the exhaust is angled in a way you can't unscrew the bolts without unscrewing the whole exhaust bracket. I can see it being a super easy install on many bikes though.

Once installed, the noise reduction was pretty significant. The exhaust is still much louder than stock but also doesn't shatter eardrums 2 blocks away anymore. The bike still sounds very angry!

I also noticed a significant reduction in the amount of popping on decel, and also the backfiring is much less explosive sounding. I plan to get my bike dyno tuned so this wasn't too much of an issue but for those who don't this would be a nice bonus as well.

Easy to install, seems to work as advertised.
This tip was easy to install on my Two Brothers M-2 slip on; just need a star driver to remove the screws which hold the end cap in place. It seems to lower the noise somewhat, especially at idle, but the tone is still pretty throaty. At high revs, the exhaust is still plenty loud. I gave it 4 out of 5 stars because I expected a more significant drop in noise. Maybe a 7-8 dB reduction just isn't that much.

C H on Jun 25, 2016
After buying the 2 Brothers Silver Series for my ZX6R , I found the pipe to be too loud. Even with earplugs, I found the slip-on to be obnoxious and it would cause rider fatigue. With the Power Tip, it tones it down the volume considerably and IMHO gives the slip on a better tone at highway speeds. You lose the idle rumble a bit but overall your ears will thank you for it.
Serge D on Jun 6, 2016
work very well and it make a big difference. its good for a normal riding and if you want to punch it the sound is still there. great product and i yes would recommend this product.

Bought this to go with my M2 slip-on. Works amazing and reduces the noise of my bike. A friend told me he could hear me coming without it from a couple miles down the road on the only road to my village in Germany. Helps reduce the need for ear plugs but still recommended to wear them even with this tip.

The two brothers m2 exhuast is very loud and wasnt sure if i would want a silencer or not....so i just bought it just in case. I run the slip on without it but if the noise ever became a problem I may give it some thought to finally install the p1x :)
Christian G on May 17, 2015

Tracy P on May 9, 2015
Softens the tone of my titanium Black Series M5. It was too loud out of the box, but this P1X makes it perfect. The exhaust is now muted on the long highway rides and in the neighborhood, but deep and throaty when you want it. Great add on for those who want their M5 pipe a bit quieter than normal, perfect for my Concourse 14.
Brett1098 on May 4, 2015
I purchased this because I wanted the option of riding around with my bike a bit more quiet as the Two Brothers tend to be a bit loud...AND IT WORKS WONDERS.

I love my two brothers exhaust. However, I had to much noise coming in my full face shoei. The P1X power tip works great. Love it. Easy install too.
Gerral S on Jul 9, 2014
I really like the reduced weight of the Two Brothers system on my ST1300. It improves handling dramatically. However, the noise was intolerable, both for me and my neighbors--especially at 2 AM, which is about my regular go-to-work time. A new re-pack did little to help the noise, so I decided to try these P1X tips, based on reviews on this website. I hope they make enough difference for me to be able to leave the TBR system on the bike.

Does it fit the 2in1 Comp-S Exhaust for Dynas?
A shopper on Jul 11, 2016
BEST ANSWER: These are listed as only being intended for use on the M-Series exhausts. They may fit, but I don't think they should be used, or will give you the expected results. I would contact 2-Bro's support to be certain, but I am going to answer no, they are not to be used/intended to fit. (from personal experience/use on a 2013 Zx6R).
