Suzuki GSXR 600 750 2011 – 2019 L1 – L9 DE CAT

“`html

The suzuki gsxr 600 and 750 models from 2011 to 2019 (L1-L9) are among the most popular supersport motorcycles in their class, and enhancing their performance with a high-quality de-cat pipe can unlock significant improvements in power, throttle response, and exhaust note. At Quill Performance Exhausts, we specialise in manufacturing precision-engineered stainless steel exhaust components that are designed to replace restrictive OEM catalytic converters, allowing your motorcycle to breathe more freely and perform at its best.

This particular de-cat pipe is crafted from premium T304 grade stainless steel, ensuring exceptional durability, corrosion resistance, and long-term performance even under the most demanding riding conditions.

About the Suzuki GSXR 600 750 De-Cat Pipe for 2011-2019 Models

This exhaust de-cat pipe has been specifically developed for the suzuki gsxr 600 and 750 motorcycles spanning the L1 through L9 model years. When you order this product, you will receive one precision-manufactured stainless T304 grade de-cat pipe that comes complete with everything you need to integrate it with your standard OEM downpipes.

Unlike bolt-on solutions, this de-cat pipe requires modification to your existing exhaust headers, which means it must be fitted by someone with workshop experience and the appropriate tools and skills.

The installation process involves cutting the standard OEM downpipes and welding the new de-cat section into place. While this may sound complex, the result is a seamless, professional finish that perfectly integrates with your motorcycle’s exhaust system. After removal of your headers, you will need a grinder with a cutting disc and either a MIG or TIG welder to complete the installation.

We provide detailed photographic instructions showing exactly where to make the cuts, ensuring that even experienced fabricators can achieve a perfect fit first time.

Installation Process for Your Suzuki GSXR 600 De-Cat Pipe

The fitting procedure requires careful attention to detail. First, you’ll need to cut the outer sleeve of the downpipe, leaving the inner catalytic converter section intact. Secure the headers in a vice positioned before the lambda sensor boss, then pull the rear section away from the front using up-down and sideways motions to separate the components.

Once separated, thoroughly clean between the inner and outer downpipe sleeves to ensure proper preparation for welding. Finally, replace the catalytic converter section with the new de-cat pipe, refit the headers to the motorcycle, and weld everything back into the correct position while the standard rear silencer is in place.

This final step ensures a perfect fit and proper alignment throughout the entire exhaust system.

Key Benefits of Upgrading Your Suzuki GSXR 600 Exhaust System

Removing the restrictive catalytic converter from your suzuki gsxr 600 or 750 delivers multiple performance advantages. The most immediate benefit is improved exhaust gas flow, which reduces back pressure and allows the engine to expel spent gases more efficiently. This translates directly into noticeable power gains, particularly in the mid-range and top-end of the rev range where restrictions have the greatest impact.

Riders typically report sharper throttle response, improved acceleration, and a more aggressive exhaust note that truly reflects the sporting character of these magnificent motorcycles.

Beyond performance gains, the T304 grade stainless steel construction ensures your investment will last for many years. This premium material offers superior resistance to heat, corrosion, and the elements compared to mild steel alternatives. Whether you ride in all weathers or store your motorcycle for winter, you can be confident that your exhaust system will maintain its structural integrity and appearance.

The weight saving compared to the factory catalytic converter assembly is also a welcome bonus for track day enthusiasts and those seeking to optimise their bike’s power-to-weight ratio.

Frequently Asked Questions

Will removing the catalytic converter affect my MOT?
In the UK, motorcycles registered after 2009 require their catalytic converter to be present for MOT testing. This product is intended for off-road use, track days, or export to territories where regulations differ.

Can I fit this myself?
Installation requires welding skills and workshop equipment. We strongly recommend having this component fitted by a qualified motorcycle technician or fabricator with experience in exhaust modification work.

What power gains can I expect?
Gains vary depending on your motorcycle’s overall specification and any other modifications, but most riders report improvements of 3-7 horsepower when combined with appropriate ECU tuning or remapping.

Is this de-cat pipe noisy?
The sound level increase is moderate when used with the standard rear silencer. The tone becomes deeper and more purposeful without being excessively loud for road use.
