Two Brothers P1X Power Tip
Stationed in Germany and had the M2 Black installed on my bike. db rating was just under 99. Law requires 95 or under. Contacted TB to verify if this tip would work. The CS gentleman said yes and to really help lower the db, order a repack kit as well. So, I ordered this tip and the repack kit installed both to spec and it lowered the db by .5. So was still at 98db couldn't return the tip or pack kit since they were used and was out the money. Ended up selling the exhaust and tips. Will never order a TB exhaust again, not because I failed, because the CS for TB just fails.

Does its job!
I recently bought this tip because i thought my s1r exhaust was too loud for my community. It does what it's supposed to do without losing power. Very easy to install and I highly recommend it to those who has two brothers exhaust.

Better sound control than expected
These power tips don't look like much, but they work great, bike sounds better with these installed. Still has all the power yet quieter. Seems pricey for what they are, but Two Brother's have done the homework and made a good product, so it's worth it.

Good concept, mediocre execution
I purchased these because the Two Brothers exhaust on my ZX6R was a bit too loud and was looking to muffle the sound a bit more.
These are great for that, although it was actually a bit quieter than I expected. Fitment seemed weird; there was no way to put this on without leaving a weird gap in the exhaust, and it seemed like it could potentially rattle off (as unlikely as that is.) Also, the paint on the tip was very poor and it would definitely have scratched off (as other reviewers have stated.)
I ended up returning it because of the fitment/durability issues; it will definitely make your exhaust quieter and I do recommend it if you're looking to significantly dampen the sound!

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.

Fast fix p1x
BOUGHT TWO BROTHERS SR1 FULL SYSTEM FOR MY FJ-09. INSTALLED SUPPER EASY. STARTED IT AND WOW DOES IT SOUND MEAN. BUT I THOUGHT IT WAS TO LOUD AND I WAS DOUGHTING IT. THEY DID HOW EVER TELL ME THAT IT IS A LOUD EXHAUST. I CALLED TWO BROS THEY TOLD ME TO GET THE P1X I DID INSTALLED AND ANOTHER WOW BIG DIFFRENCE ON THE SOUND. WAY QUITER. NOW I LOVE IT. I CAN SAY THE ONLY NEGITIVE I HAVE IS THAT NOW IT HAS A LITTLE WIERD SOUND TO IT. BUT NOTHING TO NOTICEABLE. I WOULD RECOMMEND IT 100%.

Melted in first 10 hrs of riding
So I bought it for a group ride because well the m2 is loud, went for the ride and a few other since installation, maybe 10 hours of riding a bit in the canyons running higher rpms, any way I was looking at it and it looked like some paint was peeling up on the inner lip so I pulled it off and it had melted about half the diameter and about a 1/4in. Down kinda cool looking, but I can only imagine i was shooting small chunks of molten metal going down the road

Exactly what I was looking for.
I bought my new Two Brothers pipe, and it was just a bit louder than I was hoping for. Essentially any time I fired the bike up, Manhattan could hear me coming from Queens, and I didn't want that. So I bought the Power Tip, and it cut down the decibel level just enough that the bike still roared like the fierce machine she is, but without rattling the windows of all my neighbors houses in the meantime.
