I finally got my Two Bros S1R exhaust and link pipe installed from mikem73. (Thanks again, Mike!) This is my first two brothers system and so far, so good. I always thought that the look of the carbon fiber on the S1R black edition was pretty cool. I’ve been on the bike a couple time since and it is LOUD! I usually take off for work pretty early in the morning and don’t want to be the person who wakes everyone up as I warm up the bike and leave the neighborhood. Do any of you have any experience with the p1r or p1x PowerTip? It’s my understanding that the p1r will reduce sound by 3-4 dB while the p1x will reduce by 7-8 dB. While I’m pretty sure that both options are are louder than stock (especially with a cat-delete), I am wondering if anyone thinks the P1X makes the noise level too quiet. Obviously, opinions will vary from person to person, but I am willing to take whatever I can get. What I like best is the deep throaty growl at idle and am just looking to take the edge off at higher Rpms. I suppose both power tips are cheap enough that I could buy both and test back to back, but thought I would check with all of you first. Cheers, Neil  |

I'd leave the P1X as the last resort. It's too restrictive (small hole). And at least on my ex Kawi Concours 1400, sounded worse than stock with just a slip-on. Got a P1 instead, and it was the ticket. If it's too loud with a P1, then you'd need the X, but it might cut power a little at the top, due to the small hole. Good luck.

I decided to order both the p1r and p1x power tips off of amazon to try them out. The p1x was the first to show up in the mail. Installation was easy - just 4 screws to pull the end cap off of the can, insert the power tip and reinstall the end cap. The 7-8 dB reduction makes the my commute much more comfortable. After commuting for a couple of days, I found that I had a slight desire to increase the volume just a little bit. Finally, the p1r power tip showed up on my doorstep and I installed it just as easily as the other one. The next morning, I took off for my commute and found that it definitely took the edge off (3-4 dB reduction), but unfortunately not enough. The highway portion of the commute has a concrete barrier that runs between the north/southbound lanes and the sound from the slip-on bounces off of the barrier and comes back at me. It may not be a big deal for some of you, but it definitely was for me. Ultimately, I decided to stick with the p1x and send back the other one. At this point I am pretty happy and have yet to notice any kind of performance loss. It should be noted that mainly commute during this time of year. I have yet to take it on a real ride and test it out. In the picture below, the p1x is on the left and the p1r on the right. They both look the same when installed.    |

Forgot to recommend not using the supplied O-ring; it'll eventually melt, and stick to the insert like CrazyGlue. Plus the insert doesn't sit flush (at least it didn't on my bike). I had the hell of a time removing the P1X after a few hundred miles (hot TX though), so for the P1, I just used Permatex Copper and zero play/vibration, tip sat flush, and didn't stick. But if you want to do it, do it before you put too many miles, or it'll be there for good. Finally, with the more restrictive tip, you probably erased any gains by removing the cat (meaning a tuned stock vs tuned decat), but only a back to back dyno with a tuned stock bike vs yours would reveal that, since any tune beats a stock bike. I will leave mine alone since I don't want to wash my riding gear after every freaking ride, bike is running perfectly, and want to preserve my warranty, but to each his own  . |

![]() ![]() I just got the same exhaust and i'm putting it on MT-10 as well, but some how i have a few extra pieces left that I end up not using. Is that correct? I'm not sure if I miss something on the instruction...
I'm unable to post the image here, so i just provided the link to the images of the parts I did not use.
Did you use everything that came with the TBR S1R slip-on kit? ![]() ![]() ![]() ![]() |

Got it, thank you, I was wondering if that was the washers for the O2 Sensors, but i wasn't sure, thank you !

In an email with Nels from 2wdw he said not to use the dB killer at least on my Yosh 3/4 system. He said it’ll make the bike run too rich and give you less than stock HP. Is your bike flashed?
