What to Look Before Buying R6 Exhaust

As there are many types of exhaust available in the market, you have to look out for certain features not to purchase the wrong one. Here are some of the basic things you have to keep in mind before buying an R6 exhaust.

Brand Value

While it is often easy to miss this step, we suggest you look out for the brand. Especially regarding OEM parts, if you choose the right brand, you will get a reliable product. Since the most important feature you look for in exhaust products is longevity, it is better to choose one from a reputed brand.

In our opinion, the JFG RACING brand is impressive because they have been experimenting with creating the best exhaust for R6 for a long time. Their exhaust comes with a universal slip-on feature, which allows you to use it in different models without any hassle.


To make sure your R6 comes with proper durability, you have to look out for the materials and core components. Some products arrive with an exterior carbon fiber material that you can use to cover up the exhaust. This carbon fiber often has vinyl covers that can help to keep the exhaust working correctly.

Removable DB Killer

This feature will be an excellent addition to your exhaust system. DB or decibel level killers are the aftermarket baffle you will need for your exhaust. It helps to reduce and decrease the level of noise emission. Meaning, they help to bring the sound level of the exhaust to the legally permissible level.

Some products like JFG RACING and ISTUNT come with removable DB killer options.

What component your exhaust contains will ultimately determine how well it will function. The most popular choice is a stainless steel material. This material is known for providing superior functionality and longevity.

A high-quality stainless steel material will ensure that your product does not become rusty with time.

Moreover, with standard steel components, the main issue is the corrosion of the product. You can avoid dealing with this problem if you choose an exhaust with superior stainless steel material.


Now comes the critical question of how easily you can install an exhaust in your motorcycle. If you are a new bike rider and do not know much about the installment process, it is better to seek professional help.

But some products are relatively easier to install and contains user-friendly mechanisms. A product like that is Radiant Cycles Exhaust Slip-on.

On the other hand, if you are experienced and have a knack for trying out different products by yourself without any professional help, you can choose any of the products we have discussed in this review.

Noise Level

If you feel annoyed and distracted by your vehicle’s noise level, you have to check out the exhaust beforehand. Some products come with a low-growl noise and vibration that is preferable to people who do not enjoy loud noise.

The M4 Muffler Box Eliminator is a product that will provide you an improved sound level. Therefore, you can purchase this exhaust product without any worries.
