Two Brothers P1X Power Tip
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...

definitely tones down the exhaust
Has more of an affect than I thought.
I ended up removing it as I prefer the sound without, but would buy again. Really easy install for when you need to cut it back a bit.

Works as described but...
It takes too much off the dB SPL of the exhaust for my taste. Also the metal used seems very soft... Already has a few visible nicks and dings.

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.

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

An absolute must have for a TBR exhaust
Installed on my 05 CBR600RR In less than 5 minutes using the smaller o-ring. Bike was incredibly obnoxious without it and would just irritate everyone walking around trying to enjoy their day.
This bought the sound down to a much more comfortable level, enough that you can have a conversation with someone while standing next to the bike. Sound is much more deeper and throaty. Above 6k RPM still plenty loud and fun! Makes longer rides much more bearable, and uninstalls in 5 minutes. Gold finish looks great inside a carbon fiber black exhaust. Worth every penny.

Looks good and easy to install
I bought this to keep the sound level of the new muffler as close as possible to stock. i can't say it reduces the sound, since I didn't try the muffler without installing it. What I can say is that with this tip the new muffler is barely louder than stock. It sounds great as you wind up the engine, but above 45 mph it is barely audible above the wind. I was afraid it might detract from the look of the muffler, but it doesn't. Highly recommended.
