1 X MTC Exhausts D.B KILLER / BAFFLE for the Undersump GSXR k6 k7 / ER6 Exhaust

The 1 x mtc exhausts d.b killer / baffle for the undersump gsxr k6 k7 / er6 exhaust is the precise, purpose-built solution you need when you want to tame the roar of your MTC performance can without sacrificing the quality or character that made you choose Max Torque Cans in the first place. Whether you’re heading to a noise-restricted track day, riding through residential streets early in the morning, or simply want the flexibility to dial back the decibels at the flick of a moment, this baffle is an essential addition to your accessories kit. Crafted right here in the UK to meet the exact tolerances of our undersump cans, this is not a generic aftermarket insert — it is a dedicated component designed exclusively for MTC exhausts.

At Max Torque Cans, we understand that riders don’t always want the same experience on every ride. Sometimes you want that full, aggressive exhaust note that turns heads and lets the engine breathe freely. Other times, practicality demands a quieter setup — and that’s precisely where this baffle earns its place. Noise regulations at circuits across the UK and Europe have become increasingly strict in recent years, and having a reliable, well-made decibel killer in your bag means you’ll never be turned away at the gate because your silencer is running too loud.

What Is the 1 x MTC Exhausts D.B Killer / Baffle for the Undersump GSXR K6 K7 / ER6 Exhaust?

In simple terms, the 1 x mtc exhausts d.b killer / baffle for the undersump gsxr k6 k7 / er6 exhaust is a precision-engineered insert that fits inside the outlet of your MTC undersump can to restrict exhaust gas flow and reduce the overall sound output of the silencer. Unlike cheap, ill-fitting baffles that can rattle, corrode, or affect performance unpredictably, this component is manufactured from 304 Grade Stainless Steel — the same high-quality material used throughout our MTC can range. This ensures longevity, corrosion resistance, and a consistently secure fit every time you install it.

It is important to note that this decibel killer is exclusively compatible with MTC’s own undersump outlet exhausts. Specifically, it is designed to fit the undersump performance cans made for the Suzuki GSXR K6 and K7 and the Kawasaki ER6. If you own one of these bikes and you’re running an MTC undersump can, this baffle is the correct and only recommended insert for your setup. Attempting to fit generic baffles into these cans risks a poor seal, vibration noise, and potential damage to the can’s internals — all problems that this purpose-made component entirely avoids.

Fitment Guide — Installing the 1 x MTC Exhausts D.B Killer / Baffle for the Undersump GSXR K6 K7 / ER6 Exhaust

Fitting the 1 x mtc exhausts d.b killer / baffle for the undersump gsxr k6 k7 / er6 exhaust is a straightforward process that most riders can complete in a matter of minutes with no specialist mechanical knowledge required. Because this baffle is manufactured to the precise internal dimensions of the MTC undersump outlet can, it should slide cleanly into position and sit flush within the exit of the silencer.

Before fitting, ensure the can has fully cooled down — never work on a hot exhaust. Inspect the baffle for any transit marks and give it a quick wipe down with a clean cloth. Carefully insert the baffle into the outlet end of your MTC undersump can, applying gentle, even pressure until it seats correctly. Depending on the specific variant of your MTC can, the baffle may be secured via a bolt, pin, or friction fit — refer to your original MTC documentation or contact our team if you’re unsure of the securing method for your specific model.

Removal is equally simple. When you want to return to the full open sound of your performance can — for an unrestricted run or a spirited open-road blast — the baffle removes cleanly and stores easily in your kit bag or toolroll. The stainless steel construction means repeated installation and removal will not degrade the component, and it won’t corrode during storage between uses.

As always, if you’re fitting this ahead of a track day, we recommend doing a test fit the evening before rather than in the paddock car park on the morning. It’s also worth checking the noise regulations of your specific circuit in advance, as limits can vary between venues and between sessions.

Why Choose the 1 x MTC Exhausts D.B Killer / Baffle for the Undersump GSXR K6 K7 / ER6 Exhaust Over a Generic Baffle?

This is a question we hear regularly, and the answer is straightforward: fit and quality. Generic baffles are designed to approximate a range of can sizes and outlet diameters. As a result, they rarely sit perfectly within any specific can, leading to rattles under acceleration, inconsistent noise reduction, and in some cases, partial ejection at high revs. None of that is acceptable when you’re on track or on the road.

The 1 x mtc exhausts d.b killer / baffle for the undersump gsxr k6 k7 / er6 exhaust is built to fit your can — full stop. There is no guesswork, no shimming with tape, and no fingers crossed. It fits as it should, sits as it should, and performs as it should. When you’ve invested in an MTC undersump can for your GSXR or ER6, it makes every bit of sense to protect that investment by using the correct matched components.

Furthermore, 304 Grade Stainless Steel is significantly more durable under sustained heat and vibration than the mild steel or aluminium used in many budget baffles. Over time, inferior materials can warp, corrode, or degrade — creating new noise issues rather than solving them. With this MTC baffle, you’re buying peace of mind alongside noise reduction.

Frequently Asked Questions

Will this baffle fit my MTC can if I have a different bike?
No. The 1 x mtc exhausts d.b killer / baffle for the undersump gsxr k6 k7 / er6 exhaust is designed exclusively for MTC’s undersump outlet cans fitted to the Suzuki GSXR K6, GSXR K7, and Kawasaki ER6. It will not correctly fit cans for other models or other manufacturers’ products.

Will fitting the baffle damage my engine or affect performance?
Fitting a decibel killer will alter the back pressure characteristics of your silencer slightly, which may have a minor effect on top-end power. However, for road riding and general track use, this effect is negligible. The baffle is designed to reduce noise to a compliant level rather than to significantly restrict flow.

How much noise reduction can I expect?
While results vary depending on the specific setup and measurement conditions, a correctly fitted baffle will typically bring a loud performance can within the noise limits required by most UK and European track day operators. We always recommend checking the specific dB limit for your venue.

Is the baffle reusable?
Absolutely. The 304 Grade Stainless Steel construction ensures the 1 x mtc exhausts d.b killer / baffle for the undersump gsxr k6 k7 / er6 exhaust can be fitted, removed, and refitted many times over without any deterioration in quality or fitment.

I’m not sure if I have the undersump version of the MTC can — how do I check?
The undersump can exits beneath the engine rather than at the side or rear of the bike. If you’re unsure, check your original order documentation or get in touch with the Max Torque Cans team directly and we’ll be happy to confirm compatibility.

If you’re also looking to improve flow and performance at the other end of your setup, take a look at our BSA Gold Star de res pipe 304 Stainless Steel — another example of the quality stainless steel fabrication that Max Torque Cans is known for across the UK performance motorcycle community.
