Noise regulations are tightening across the UK and Europe. Trackdays increasingly enforce strict drive-by noise limits, and local councils are cracking down on loud bikes in urban environments. This baffle gives you the freedom to run your GP PRO can in full, unrestricted glory when the road is open and the conditions allow — and then slip this insert in when discretion is the order of the day.

It’s the smartest accessory any GP PRO owner can carry, and it ensures you’ll never be turned away from a trackday or face unwanted attention from noise enforcement officers.

Why Choose the 1 x MTC GP PRO Decibel Killer / Baffle / DB Eater Ø63mm Exhaust Silencer Muffler?

This isn’t a cheap, poorly-fitted insert that rattles around and falls out at speed. This is a purpose-built, correctly sized decibel killer designed specifically to fit the outlet of the Max Torque Cans GP PRO exhaust. The Ø63mm diameter is matched precisely to the GP PRO outlet, ensuring a snug, rattle-free fit every single time.

When you invest in quality exhaust components, you deserve accessories that meet the same exacting standards — and that’s exactly what you get with this professionally manufactured baffle.

The 1 x mtc gp pro decibel killer / baffle / db eater Ø63mm exhaust silencer muffler is manufactured in-house from 304 Grade Stainless Steel, the same high-specification material used throughout our GP PRO performance can range. This means you benefit from exceptional corrosion resistance, high-temperature tolerance, and a long service life that will see you through countless seasons and trackdays.

Cheap mild steel baffles corrode rapidly and can seize inside the can, making removal a nightmare. With 304 stainless construction, that problem simply doesn’t exist.

According to the Motorsport UK regulations, many circuits enforce noise limits as low as 98dB or even stricter, making a removable decibel killer an essential piece of kit for any serious trackday rider. Having this baffle on hand means you can adapt to any venue’s requirements without missing out on valuable track time.

Premium Materials and Construction of the 1 x MTC GP PRO Decibel Killer / Baffle / DB Eater Ø63mm Exhaust Silencer Muffler

At Max Torque Cans, we don’t cut corners on materials — and this baffle is no different. The stainless steel construction stands up to rain, road salt, and the harsh thermal cycling of a working exhaust without rusting or degrading. It’s able to withstand the extreme heat generated inside a performance silencer without warping, cracking, or losing structural integrity.

The clean, professional finish looks the part even when the baffle is visible at the outlet of your can, maintaining the premium aesthetic your bike deserves.

Many riders keep their 1 x mtc gp pro decibel killer / baffle / db eater Ø63mm exhaust silencer muffler permanently stored in their trackday kit bag, ready to drop in within seconds before a sound test. The simplicity of the system means you spend less time faffing around in the paddock and more time on the bike where you belong. It’s a small, lightweight component that takes up minimal space but delivers maximum peace of mind.

Fitment and Installation of the 1 x MTC GP PRO Decibel Killer / Baffle / DB Eater Ø63mm Exhaust Silencer Muffler

Fitment could not be more straightforward. The 1 x mtc gp pro decibel killer / baffle / db eater Ø63mm exhaust silencer muffler is designed exclusively to fit the Max Torque Cans GP PRO outlet. If you’re running any other exhaust or can, please check the outlet diameter carefully before ordering — the Ø63mm sizing is specific and must match your outlet for a correct, secure fit.

Installation takes just moments. Allow the exhaust to cool completely before attempting to insert or remove the baffle — working on a hot can is dangerous and can result in serious burns. Insert the baffle into the outlet of the GP PRO can, ensuring it seats fully and correctly at the Ø63mm diameter opening.

Secure as per your can’s fitting arrangement, and double-check it is seated properly and won’t work loose before riding. Removal is equally simple: allow the exhaust to cool, then withdraw the baffle and store it safely for next time.

This baffle works perfectly as part of a comprehensive performance exhaust setup. If you’re building out a serious package for your bike, consider pairing your GP PRO can with our Aprilia RS660 De-Cat DownPipes or the Triumph 765 Moto 2 De-Cat pipe, both manufactured to the same exacting standards and designed to unlock serious performance gains throughout the rev range.

Frequently Asked Questions

Will this baffle fit any aftermarket can?
No. The 1 x mtc gp pro decibel killer / baffle / db eater Ø63mm exhaust silencer muffler is purpose-made for the Max Torque Cans GP PRO outlet specifically. The Ø63mm diameter and the design of the insert are matched to our can. It may not seat correctly or securely in other brands’ silencers, and we cannot guarantee fitment or safety outside of the GP PRO application.

How much will it reduce noise?
The reduction in decibel output will vary depending on your specific bike, engine configuration, and riding conditions. The primary purpose of this insert is to bring a loud, free-flowing performance can within acceptable limits for noise-regulated environments such as trackdays and noise-sensitive roads. Real-world results are very encouraging for customers who use it for exactly this purpose.

Can I ride with the baffle in place permanently?
Yes — the baffle can be left in the can for regular road riding if you prefer a quieter ride on a daily basis. Many riders use it Monday to Friday on the commute and remove it for weekend blasts and open road riding. The 304 stainless steel construction handles the heat and vibration of continuous use without issue.

Does inserting the baffle affect performance significantly?
Any restriction at the outlet will have some effect on back pressure and power output, particularly at the top end of the rev range. For road use and trackday compliance purposes, the trade-off is entirely acceptable. If ultimate peak performance is the priority in an unrestricted environment, simply remove the insert and run your GP PRO as nature — and our engineers — intended.

The 1 x mtc gp pro decibel killer / baffle / db eater Ø63mm exhaust silencer muffler is a small investment that massively increases the versatility of your GP PRO can. Order yours today and never worry about a trackday noise limit again.
