Two Brothers M-2 Slip-On Exhaust
Great TwoBros exhaust!
I bought this exhaust after doing a lot of research on different aftermarket exhaust and this one ended up being one of the better ones out there for a slip-on. I got the carbon fiber black series model and it looks and sounds great! It definitely gives it a little lower end growl and is louder than stock. It also adds a few horsepower to the bike.
The install was pretty easy. The hardest part was getting the servo cables disconnected on my '07 R6, but it still was pretty easy. It took me about 45 minutes to fully install, but it would definitely have gone faster now that I know exactly what to do. The instructions they give are very informative with pictures so you can make sure you are doing everything right. Overall I am very pleased with this exhaust and look forward to using it this season. Revzilla was great as always with very fast shipping!

I bought the slip-on for my girlfriend's Ninja 250. We didn't like that the stock exhaust was so quiet so we checked out a few options. We took a look at the Yoshimura, Akrapovic, and finally found Two Brothers. Fortunately, we had friends that had each of these exhaust slip ons and we loved Two Brothers the most. As others have stated, it is VERY loud, but we love the deep guttural sound to it.
The item came with installation instructions. Installing the slip-on was more difficult than taking the stock exhaust off, lol.
We are very happy with this item and would recommend it.
I also wanted to add that we got the item in two days!! Ordered it on Monday and it came in the mail on Wednesday. Love RevZilla. Can't wait to buy the next item!

This product is great
This slip on exhaust was probably the greatest item i have purchased for my bike. The look is amazing and for it just being a slip on the sound is extraordinary.

Looks and sounds great on my Ninja 250
I was surprised at the price on RevZilla, its roughly $100 cheaper than going straight through TwoBrother's website and is less expensive than other sites as well. It makes my bike look nice, sounds wonderful and I feel more safer with my bike actually being a louder than with the stock. Also a noticeable boost in power. I highly recommend this for the price. It's not difficult to install either.

The notes on the TBR are a symphony! In my opinion, its the best sounding slip-on.

Great sounding/looking exhaust for the cost
Overall I'm happy with this exhaust. I installed on a 2011 zx6r. It is pretty loud but not as insane as some others I've heard. I rode my bike for a few days and decided to order the P1X insert to tone it back a bit. I like to use my ear buds for music while riding a lot.
First off the look. It looks so much better on my bike compared to the stock exhaust. I really like being able to see more of the wheel. I've seen a lot worse stock exhausts than my 2011 zx6r but still a big improvement.
Now for the sound. It is nice and loud but also surprisingly deep. I looked through just about every exhaust for my bike I think and I was really worried about ordering one and just not liking it. For me it was down to the Werkes pipe, this one, and the Muzzy. Here is one thing I really like about two brothers over the other 2. If you go to two brother's website and you pull up their exhausts they actually have a table that shows the Db levels at 5k rpms. They also have the inserts listed in there as well. That gave me a lot more confidence in this pipe and the inserts available. After a few days of riding it I decided to go with the P1X insert so I could still listen to music and I'm sure on longer rides the standard sound might have been a bit much. Due to the information two brothers provides on the website I knew it would make a big difference and it really does.
Performance is interesting on a mid pipe/muffler like this. It's not a full race tuned exhaust. I will say the biggest difference I've noticed is losing about 15lbs from taking off the old muffler and the stock cats. I'm sure there were a couple of hp gained but from riding the bike I can feel the weight difference. I also notice better throttle response. This could be due to how everything works on the 2011 zx6r though. It has a valve that turns inside the stock muffler that opens it up. Obviously that's not there anymore. Combine that with a couple horse power and just the fact that it is more open and that's probably why. Not a huge difference but it is a slight difference.
If you're too concerned about sound to purchase this pipe I recommend visiting two brother's site and checking out the information for your bike. As I said the charts that show the sound levels at 5k rpms gave me the confidence that I could go with this exhaust and change it to what I wanted with one of the 2 inserts available. The build quality is fantastic, the instructions aren't too bad, and had I not already had a fender eliminator on my bike this would have been a much better value. The good news is a friend of mine can use it so it didn't go to waste at least.

Overall Great Product
Took a little longer then expected to install but overall a great product. I have the carbon black series and it sounds amazing. The can is so much lighter than the stock muffler its insane. Great deep tone through out the rpms and a nice "gurgle" sounds on the deceleration side. I can really notice a difference around the 7,000 rpm range in sound and in power. I was really surprised at the power in the higher rpm range after the install.
