Exhaust Opinions Needed

I've been looking to replace the stock exhaust in my Ninja 400 for a long time,. I for sure wanted a slip-on exhaust, something LOUD, and something that cost me $300 max. Obviously I plan to save up for it because I want to get a decent quality exhaust that will definitely last me, I want this to be my first and last exhaust purchase.

After some research, I was deadset on getting the Hindle EVO Megaphone, which was the loudest one I could find in my price range:
https://www.revzilla.com/motorcycle/...ninja-400-2018

Decent quality and just the sound I was looking for.

However, my friend told me that the Hindle one was EXCESSSIVELY loud, I want to be loud, but not TOO obnoxious. So I was given some suggestions to check out the brand "DanMoto", he said that their exhausts are much cheaper and just about the same quality. So the one I ended up looking at was the Danmoto MK2 Slip-On:
https://www.revzilla.com/motorcycle/...-400-2018-2020

I realize this was more ideal as it was:
1. Cheaper than the Hindle
2. Slimmer/more low profile/lighter than the Hindle, something that I realized I wanted as well
3. Maybe just as loud as a Hindle.
4. Has a mostly black/carbon finish compared to the mostly silver Hindle

However, like previously mentioned, I wanted something that would LAST me, and be good quality. After reading the reviews for the Danmoto, many people said they received broken/worn parts and others had to makeshift the mounting as they did not provide the correct mounting. Other than that, the exhaust was still fairly good and loud.

This took me to finding the next exhaust, the LeoVince GP Corsa EVO:
https://www.revzilla.com/motorcycle/...ninja-400-z400

Also very loud as well, slim profile, and carbon/black color that I prefer. However it is closer to the price to the upper-range Hindle. Though this is probably a given considering it is the well-known brand name of Leo Vince.

So now for my final dilemma. Should I save a bit of money and go for the Danmoto exhaust, and risk the possibility that it MAY not last me as long or be as good quality. OR, should I dish out the extra $100 and go for the LeoVince? What do you guys know about the brand/quality? Would it REALLY be worth the price? And would it be louder by any chance due to the inrease in quality? Thanks for your time.

Welcome to the forum.
If you are only looking into the sound, go with the cheapest but if you are looking into the performance, go with full exhaust and you will feel the difference.
Keep in mind that you may need to tune your bike again, after installing the canister, and for sure if you install the full exhaust.
What I have experienced, it was a millisecond throttle hesitation when replacing the canister on my 06 600GSXR and to fix it, I had to install a Dynojet mapping to tell the Bike computer that now the bike has an aftermarket slip-on and air filter.

Thanks for the input, however, they are ALL slip-on exhausts, none of them are full system. I mainly needed guidance on if one slip-on is truly better than the cheaper one, or would its quality affect more than just sound, such as better performance?

Yes it will change from one to another as far as sound, performance and final product quality IMO.
They made these aftermarkets products not just for looks and sound.
It's mostly designed with the TRACK/RACE use purpose to get better performance.

Here is what I found to give you an idea.
Here it's only showing the two brother slip-on but you can see the gain in performance

Here is a website I found with some good info about the subject.
https://www.norton-motorsports.com/

P.S. You will need to take your bike into the shop to get it DYNO tuned after installing the canister or full system to maximize the performance.

I've always had good experience with M4 - They are in Dallas so you're supporting Texas business. Had their pipe on my SV - good deep sound; GROM - loud; and FZ10 - really deep sound, makes the crossplane I-4 sound even better (also came with a baffle to make it more quiet).

I'm a fan of M4 myself but I was actually very impress to see how much gain the "two brothers" slip-on is given compared to all full systems...

Hey You! Glad to see you on this forum as well. I had the same concerns you have regarding the Ninja 400. I searched for months before I went with the Two Brothers Racing S1R Black Series (Carbon) Slip on.

I installed it myself and it was super simple! The only major issue I had was removing the stock exhaust (needed a lot of elbow grease). Anyway, here are pics of my can on my bike and I've also included a video of what the muffler sounds like. IT is extremely loud as I do not have a baffle, however, no one looks at me with disgust when I ride by so I don't think it's loud enough to annoy others. I do prefer to ride with earplugs because of the loudness.

I've also included another video of how the bike sounds at highway speed. Hope this helps!

I called TBR and asked if I needed to get a tune with their Slip on and I was told I did not. I've been riding with it for a over a year now and no issues.

I've had 2bros on my old SV, but it was full system. Good one too. I completely forgot about this....it's been over 10 years ago though.

good to hear.
what it usually happened was the throttle not been 100% responsive.
I would say a millisecond hesitation enough to upset the suspension in mid turn, when you are in full lean and committed to the turn.
please take in consideration that it has been a very long time since my last street ride, and at the track, usually I'm either on my limit or the bike limit.
