Two Brothers S1R Black Series Slip-On Exhaust Kawasaki Ninja ZX-6R / ZX-636

The Two Brothers S1R Black Series Exhaust takes the state-of-the-art S1R design to the dark side with black billet aluminum inlets, stealthy TBR badges and Two Brother's signature carbon fiber weave. The S1R produces that deep and throaty sound that TBR is known for thanks to their spiral-wound perforated core technology. The rubber lined natural finished aluminum muffler clamps feature an aggressive angular design and cutouts to reduce weight. The mid-pipe is constructed from .035” thick 304 stainless steel. After a few heat cycles the 304 steel turns a golden amber color, the hallmark of quality stainless. Of course an exhaust can't be all show and no go, that is why the S1R exhaust is track tested and dyno tuned to offer the best performance package.

Features:

  • Aerospace high-temp carbon fiber
  • Stamped spring-fit inlet
  • Optional P1 and PX1 sound inserts available (sold separately)
  • Optional anodized bolts kits available (sold separately)
  • Made in USA

Sounds and looks amazing!
This slip on is a game changer. It sounds incredible and is definitely loud. On longer rides I wear ear plugs and it still sounds great. It looks incredible on my ninja 636. Only thing I didn't like was the aluminum finish of the mounting piece around the pipe itself. I painted that black to match the pipe. The install was a little complex for someone who isn't mechanically inclined. Had a little trouble getting it mounted correctly because the mid pipe is funky. After a second pair of eyes I realized it took turning it slightly and everything lined up perfect! After 200 miles I love it!

The feeling when you get exactly what you want.
I wanted an American made, quality, throaty, loud-as-hell exhaust, that also looks great. I got it. The carbon fiber black series screamed, but not in a bad way. More like a male opera singer on cocaine instead of a whiny punk rock singer. This exhaust is perfect for the ZX-636 in my opinion. Don't spend more on Akrapovic. This truly is a better product. I used to think "oh, well it cost more, must be better" I couldn't have been more wrong. By Two Brothers. They even include a fender eliminator WITH LIGHTS. Also, take your time installing. Actually read the directions. I rushed through like a kid on Christmas Day tear the wrapping off presents. This is not the same thing. READ THE INSTRUCTIONS, TAKE YOUR TIME.

Kevin P on May 14, 2016
BEST ANSWER: Yes it does. Although I didn't install it since i took care of that months before I bought the exhaust. I get tons of compliments on this thing! It is pretty Damn loud so keep that in mind!
If I buy slip on exhaust can I buy headers later?
