Take your Vulcan S to the next level with the Two Brothers Comp-S Exhaust System. The Comp S features manufacturing processes that were previously only founded on racing exhaust systems. The headers and midpipe incorporate TBR's stepped exhaust technology that creates a vacuum effect that forces hot exhaust gases out, allowing your engine breath better while simultaneously increasing horsepower, torque and throttle response. Additionally a pipe bending method known as mandrel bending is used and prevents wrinkles and ovalization of the exhaust pipes

Features:

  • Designed and tuned for max torque and increased horsepower
  • Swept-up muffler for enhanced ground clearance
  • Carbon fiber end cap
  • Mandrel bent stainless steel tubing
  • Hand TIG welds

BADD AZZ!!!
Super light, easiest exhaust to install ever! Sounds loud, mean and straight up Bad! Thumps! Very loud! I will start wearing ear plugs tomorrow... Check engine light comes on and stays on probably because no CAT. My friend rode it around my neighborhood and I am in love! My wife has the exact same bike and exhaust and she loves it too! Says get out of my way! We bought black to go with white bike and black bike. Looks fantastic! Revs quicker, faster, more free.

Great Sound!
Installed this exhaust over a couple beers and it went real smooth, it's really just a few bolts and done. The sound is much louder than the stock exhaust and sounds great. No check engine lights, I did unplug the battery to do the install. During rides I would get popping on decel and the engine did seem to run a little warmer, so I got the Power Commander tuner, they have a map for this exhaust. Now it runs great, has better power, and doesn't run warm. If you don't mind the pops or the warmth you can do without the tuner.

Very good Exhaust
So i got the Comp S exhaust because the stock was just too quiet. Well... it did its job. It is Extremely loud. In fact much louder than i expected. Video clips and recordings do not accurately depict the sound levels accurately It is MUCH louder. Neighbors may not be so happy if i were to take it out at night. Very deep throaty sound when at low end rpm. and roars to life once you hit the throttle. On the road i feel more safe because the sound is definitely noticeable. Overall, i would say it is worth it.

Easy install. Looks great. Drops weight. Sounds amazing. Soft pur at constant speed. Great throaty sound on acceleration and downshift. Adds power. A bit expensive but well worth it for a new bike. Be aware that you will make neighbors mad while it worms up.

annoy EVERYBODY including yourself
Bought and installed primarily for the HP increase, not sound. Yes, stock it's rather blah so desired A "lil something" extra for sure. So, I bought the kit and a Power Commander. Easy install, and I ain't no handy man / grease monkey. Looks amazing, dropped 12 lbs I think off the bike. Increase? Holy jebus batman hell YES! Top end prior with my 250 pound butt on it ~107 mph. Post TB + PWCV ... ~117 mph and a serious boost in quickness + the entire shift pattern / rev range changed. BUT BE FOREWARNED, I will tell you here the the noise pollution is 100% intolerable. People walking down the street would constantly turn around before I even passed them. And it is a freaking 650 cc bike! WTF?! Drove to their (2 Bros) HQ near my house and they hadn't perfected the sound dampener insert yet for that kit like they offer for others.

Awesomeness
I have had this exhaust for a little over a year now and it is a awesome exhaust! I just put on the all new db killer from two bothers and it makes it much more tolerable because it takes away the sharpness of the sound!

Power gains
I bought this exhaust because I wanted to hear my bike more both for safety and personal preference as the Vulcan is really quiet stock. The power and sound difference is incredible. It sounds way louder than it did in the YouTube videos I watched leading to the purchase which for me was a huge positive. The power gain is more than noticeable, I can now break the tire loose at speed in second gear if I want to. My only complaint is with the bracket they use to join the pipe and the muffler. Despite readjusting several times there is a little exhaust leak where they meet. Also for the blacked out version I would have liked that bracket to be black rather than the typical shiny metal which clashes with the rest of the bike. Overall I am very pleased with my purchase and would recommend it to anyone looking to get more power out of their bike.

Install was perfect except the washer that was provided. I had to use a drimmel and widen the opening on the washer. The silencer does fit without o-ring but leaves small space between exhsust and carbon fiber tip.

Sweet set up
I bought this exhaust system for a 2015 Vulcan s. I could not be happier with the performance the looks and the way it sounds. This was the best money I've wasted in a long time on a need!

Easy install and GREAT sound.
I got this for my wife as she was not happy with the stock sound. This pipe is LOUD! But in the best possible way. The bike def pulls harder now and it looks great on the bike. The weight savings is another plus. My neighbors are cool with the volume level as they all have loud bikes too but I can see this pipe pissing people off.

Sounds incredible, but beware, is loud and had neighbors really looking at me. Followed up by purchasing a P1X Power Tip, which helped the loudness greatly and kept the sound, but had to a little modifying for the tip to fit.
W I on Feb 24, 2017
It sounds like a beast! brings the bike to life..
D B on Jul 29, 2016
Videos and Reviews have made it sound like a great item but in the end it seems to be the only "easy" exhaust for the vulcan s
Zachary L on May 20, 2016
The sound of this pipe is amazing, heard it in videos. Great increase in HP.
Ian L on Mar 5, 2016
THE FACTORY EXHAUST ON THIS VULCAN S IS JUST PLAIN GUTLESS! I WATCHED THE VIDEO THAT TWO BROTHERS HAD ON THIS SYSTEM, AND WHAT A STARK DIFFERENCE! I JUST LOVE THE SOUND AND THE LOOK OF THE TWO BROTHERS EXHAUST SYSTEM,ALSO THANKS REVZILLA FOR THE BEST PRICE AVALIABLE!

Has anybody installed this exhaust with a power commander? If so what were the results and is it worth getting a power commander?
Matthew L on Apr 14, 2016
That's a significant torque loss according to the Revzillia chart, is that accurate?
A shopper on Sep 10, 2016
BEST ANSWER: I haven't noticed a torque loss at all though I am by no means a professional. In fact my bike can now break the tire loose and has popped the front tire up in 3rd gear.
It mentions that this is not street legal but instead only for closed course. Is that true for all over the US, or is it dependent on state? If dependent on state, how do you look up to see if it is legal in mine?
brumms013 on Oct 22, 2015
BEST ANSWER: I LIVE IN OKLAHOMA AND RIDE ALOT ALSO IN ARKANSAS, THE SOUND IS NO LOUDER THAN MANY HARLEYS I'VE HEARD! AS FOR WHAT STATES ALLOW I'M NOT SURE!
Does it fit 2017 Vulcan s ?
A C on Mar 13, 2017
BEST ANSWER: Just installed this on my 2017 Vulcan S...super easy install!
What kind of sound does this put out, Is it throaty like a harley? I am not pleased with the quite lawnmower sound the bike makes, lol.
Adam O on Jun 15, 2015
BEST ANSWER: Very throaty. Better than Harley. Harley has the raspy sound. This thing has bass. You can feel it. On the throttle you are very noticeable. Constant speed is a nice purr. There is a bit of backfire like open pipes.
I installed a Two Bros Comp S exhaust system in my Kawasaki Vulcan S & the sound is too loud for my neighbors. What type of decibel reducer shall I buy from you? P1 or PX- 1 ?
Innocencia D on Sep 29, 2017
BEST ANSWER: this is America and you do have a right to have a loud exhaust as long as you're not revving it up throughout the night it should not matter.
The one review on this site states, " Check engine light comes on and stays on".
Is this normal? Does the bike need to be chipped or reprogrammed?
Brad G on Oct 12, 2015
BEST ANSWER: Had mine installed professionally. Cost $60 in labor. No chip. No check engine light. O2 sensor related, but I t can be done- I just don't know what magic the technician used.
I'm still fairly new to motorcycles. When people say they have the Power Commander, which one is the correct one?
Tyler C on May 17, 2017
BEST ANSWER: According to the Two Brothers Website you don't need a PC. I bought this exhaust and it sounds amazing. Definitely worth it. The bike runs better and I feel I get a little more power, so I don't see why you would need a PC.
Does the exhaust come with new seals or did everyone use the existing seals?
Robert K on Apr 2, 2017
BEST ANSWER: I used existing seals bike only has 400 miles. If u have a few thousand miles then I would replace them
A bit confused can this exhaust be used here in California?I commute to work on my bike daily.
A shopper on Oct 21, 2016
BEST ANSWER: This product is legal in California only for racing vehicles which may never be used, registered or licensed for use upon a highway. So no, it shouldn't be on the road to work legally.
