Coffman’s Shorty Slip-On Exhaust for Kawasaki Ninja 400 Z400 2018-2021 Sportbike with Black Tip

My Z400 has a slip-joint that comes loose after a while This is a very impressive sound. The sound seems to be a lovely combination of low-end and high-end A purr at the octave. You may prefer the more tinny, high-pitched sound There is no slip-and-fall here - this is the pitch- I'll take care of It took me around 20 minutes to install this on my bike, even though I don't have any mechanical skills. Unless you're skilled, it should take less than half the time. Also, my slip-up meant I was unable to enter the data. One day before the expected delivery date, on arrived. As a kid at Christmas, I felt like a king or queen. I love it! When I turned on my bike, I couldn't help but smile. It sounds like a whole new bike. When I took off, my bike backfired twice, and that was the only backfire I encountered during my 30-minute The temperature was probably just mild, but it took a while for everyone to get used to it. The sound of my bike purring while I rode brought butterflies to my stomach as I rode into work. There is no way my bike can get any better than this but the Coffman exhaust is definitely a game changer! I highly recommend that you purchase it!.

In a nutshell, It is a good slipper to recommend My heart beats faster than a speeding bullet. Installation and removal were easy and took about 20 minutes. About 80-percent of the way in There is a sound of 84db. In comparison to that huge silencer included with the bike, this one makes the Ninja 400 sound as an actual motorcycle. I also saw a nice drop in weight. It's great to find such a good price here.

The great packaging that it came in took me an equal amount of time to open as the removal of old exhaust and installation of this beautiful exhaust. I really like the color scheme, and I like the sound as well. As well as the decals, include two stickers. Excellent exhaust. I highly recommend it.

Despite not having installed it yet, I intend to do so. We are waiting for some down time to do this. We found the Muffler to be well made, there are no seams in the welded seams, and there are color tip options available. I bought one for my 2018 Ninja 400 when I heard a few people demonstrate how it sounds on YouTube. As well as showing an open box demo, instructions on how to install, and a Tee shirt bearing the Coffman's logo, those who showed this exact muffler also showed an open box demo. After ordering a pipe for my bike, I messaged the seller to let them know what size shirt I was wearing The result would be much greater if the T-shirt was still FREE They have shirts with their logo on them. Despite repeated requests, they have never referred me to It came in a box with just the muffler and a note telling me to go online for instructions. When I received the muffler, I didn't find any other items inside the box other than the muffler and the note. As a beginner, I don't know how the Coffman products sound. Therefore, I find it difficult to say how they perform. My muffler tail pipe is easy to install on my own, so I didn't need any help, but I wasn't happy they didn't include instructions or fitting tools There's no shirt. In the end they did not reply back to me stating that they were out of stock or didn't provide promotional items with my As long as I don't remove the baffler, I believe the muffler will increase engine noise a bit. From what I've seen and heard on YouTube, it will do this without allowing the engine noise to increase. As for removing the baffle, it will lead to the bike backfiring, and this is not good for the engine. If you run it without the baffle, the boat will be louder, but you'll also lose power and may have more issues with the top end.

I installed this on my Kawasaki Z400 recently, and it looks a thousand times better than its stock counterpart!

The installation took roughly 30 minutes, but I struggled to figure out whether the bracket should be behind the rear mounting bracket or in front. It seemed to me that it angled and looked better in front than it did In addition, the exhaust arrived ahead of Amazon's estimate of when it would arrive, and the exhaust shipped within 24 hours.

This is a great product! I used it with my 2020 Ninja 400 with no problems. This took less than a minute to set up. WOW! Just think how much better the sound is now. There is still a lot of sound, even with baffles in. I would highly recommend this product.

Those sound like a beast! I'll be getting a Ninja 400 in 2019! I love the way this looks and sounds! The installation process is easy. Having a 14 year old installing it for me was a big deal for me since I'm a woman. After taking the factory on and putting on Coffmans, he was finished in less than 10 minutes! I highly recommend this product! The shipping was fast. It's been great working with you guys!.

The installation was easy and the quality was excellent. The welds and materials appear to be of the highest quality. On my previous bike, my exhaust was from Toce, and this one looks, sounds, and feels as good to me as my old one. Even when the bike is idling in the garage, my riding buddies have been complementing the look and sound of this exhaust! I have not yet moved the baffle so I do not know about the interior sound and look. Despite being clean and sleek, it stands out surprisingly well and I hope Coffman will make a slip on in the future for my entire fleet of bikes!.
