with any exhaust if you listen to it on youtube or the likes the audio doesn’t do it any justice.

everyone will chime in & tell you the same, their exhaust sounds good, and i have no doubt they do, its all a personal choice. i have a 2 bro's slipon and im impressed with it

 

I'd go yoshi just with the plain fact I love its looks over the others ! I believe most have almost same sound, and with slip-ons you don't gain extra horsepower, its just sound. Full systems will give extra hp if you add powercommander and air filter and tune and what not

you can go pretty close the power of the full system by taking your bike to an exhaust shop with a TIG welder & get the catalytic converter removed from the stock exhaust. i have found a local shop that can do it for $120

 

I'd recommend a Musarri slipon, they look pretty great and sound awesome. I have one I'm willing to sell if you like, it's a C/F version, be able to find a photo of it on my bike in my pics somewhere + it's like half the price of a yoshi.

 

Don't know where you are getting the "thumbs up" on power and "suffers badly" on sound quality. Certainly not around here. Anyone that tells you the slip on made horse power gains is lying and anyone that tells you it sounds like a$$ doesn't know sh!t from shinola.

All the slip on is going to do is (1) change the sound signature of your bike, (2) look pretty effing cool doing it and (3) reduce some weight. I personally like the the sound of this slip on. Points 2 and 3 are icing on the cake. Yoshimura makes a quality product and you will be hard pressed to find anyone to state otherwise. You've been misled regarding Yoshi...

 

I have to agree. To get a HP gain you have to full exhaust and doing that you need to re-tune.

I am sure my M4 slipon didn't add any horsepower. However, it sounds great and coupled with a K&N air filter it shifted the "power band" up my tach about 1000 rpm. So... I suspect it may have tweked my torque a little tiny bit but without a dyno we will never know.

You're generally going to see a slight performance loss with any slip-on over stock as the stock can has some extra restriction on it. Adding most aftermarket slip-ons will open up a small bit of airflow and reduce back pressure a little bit. Which is why you get the burbling and popping and even a real felt performance loss when you take some slip-ons and remove the baffle. You really need a tuner to correct the fueling for the reduced back pressure and get some of that slight loss in power back. With everything tuned properly for most slip-ons, you may see a .03 of a torque increase with the slip-on but the bigger thing is that you'll get some of the lost power back and reduce or eliminate backfiring during deceleration. Mainly, as said, the slip-on is there to reduce weight, get something that doesn't rust out, and generally looks and sounds better than the stock muffler. Asking which one is better is like walking into a concealed carry meeting and asking which piece is better. They all have their uses, pros and cons. It all comes down to what makes your pants tighter vs wallet happier.

 

Keep in mind whatever brand you go with, weight savings will also equal a HP gain.

Every 6-7 lbs lost is equal to about 1 HP gained.

Most our guys tent to prefer the sound of Yosh or TBR on the 300, fwiw.

Like what many others already said, any slip on will not give you the extra power you're looking for. For that you'll need a full exhaust system with an ECU tune. I also switched to a KnN air filter. I did all this without really enjoying the bike stock so I can't tell the difference but putting my worthless two cents in, I love yoshimura products just because they look pretty great.

this is true only if you add the slipon with nothing else.

if you add a slipon, also add a k&n, & tuner of some kind and you will get the power back

 

If you want the extra HP's, you're going to want to get a full system. The slip-on isn't going to give you hardly anything. It will reduce weight (which technically gives you a slight bump in HP) but for an extra $100 and some change, you can add much more HP with a full system. Add a ECU flash or PC and a K&N filter, and you're getting the most out of it in my opinion.

I have the R-77 full system and it gives the little Ninja quite a boost. Plus, it sounds awesome. You'll definitely want to keep the baffle in if you don't want the sound. The full system is also much more pleasing to look at in my opinion. Looking at a slip on installed to the stock pipes just doesn't do it for me.
