I got this for my exhaust so I would not upset my wife all the time. Idles softer and does not make your ears ring as much at high rpms. You don't lose that low rumble and people still know where you are. My bike is the 05 zx6r 636. So I had to buy 2. The only down side I found was the bolts on the exhaust are really soft and strip easy take your time.

Looks nice but doesnt quiet it verey much. Product arrived fast as always!

The Good:
Quiets your exhaust to a not so obnoxious level

The Bad:
I followed the instructions using the smaller o-ring since the larger one did not fit. Tightened the bolts all the way down so the lock washers would activate. Well, 200 miles later the whole thing fell off taking my endcap with it. I called two brothers asking for help but they said there was nothing they could do and had no recommendations for me..but that I could cough up $65 for a new endcap which doesn't include the bolts which are $20 extra (yes seriously), and $30 for the powertip. After talking to local shops that carry two brothers parts, they said I'm not the only one. That two brothers exhausts are known for falling apart while on the road, and that they likely make a good chunk of their money on overpriced replacement parts.

My advice if you choose to buy this is to use loctite on the bolts or at the very least retighten the bolts after everything heats and expands from going on a short ride.

This is a great addition to my Two Brothers Exhaust. Got it for longer trips to help out the ears a little. Quick easy on and off install

This does the job - takes the exhaust volume down just a few db's without changing the tone at all, looks great too! The cool thing is it only takes 5 minutes to install / remove, so you can pop it on or off easily.

Comes with a gasket / spacer, fits nice & tight.

After purchasing Two Brothers mufflers I soon found myself considering my neighbors and used power tips to give me the note I wanted without being offensive.

The stock 2 Bros pipes where a little too loud for my liking, these power tips reduced the sound just enough to keep the nice crisp sound. Very easy to install.

Tones down the two brothers pipe on my 2014 Vstrom 1000. But you don't loose that deep sound.

The main reason I bought this was in case I got any blown lack from my local track about exceeding dcl levels. So for @$30 it's not a bad accessory. HINT- If you don't have it installed when riding around town, keep it in the tail section (or in my case my back pack) that way if you get a Barney Fife giving you trouble you can show it to him and explain that you were testing the exhaust without the insert and you plan on putting it in when you get home.... idk.... might help ya keep from getting a ticket! :)

Installs real easy, looks great and reduces the exhaust note so as not to offend the neighbors in a hight density area.
