TRIUMPH STREET TRIPLE 675 2008-2013

The street triple 675 stands as one of Triumph’s most celebrated naked sport motorcycles, combining agile handling with a punchy three-cylinder engine that has captivated riders since its introduction. At Quill Performance Exhausts, we’ve engineered a premium exhaust system specifically for the Triumph Street Triple 675 models produced between 2008 and 2013, delivering enhanced performance, weight savings, and an unmistakable exhaust note that complements this already impressive machine.

About the Street Triple 675 Exhaust System

Our exhaust system for the Street Triple 675 has been meticulously designed to integrate seamlessly with your motorcycle whilst providing tangible performance benefits. This comprehensive kit includes everything required for a straightforward installation, featuring two stainless steel 304 CNC mandrel bent link pipes that ensure optimal exhaust gas flow. The precision engineering behind these components means you benefit from improved throttle response and a noticeable increase in mid-range power delivery, exactly where the street triple 675 excels.

Each exhaust system comes complete with two stainless steel exhaust straps and two exhaust strap rubbers, providing secure mounting whilst minimising vibration transfer to the chassis. The beauty of this system lies in its direct fitment approach—it’s manufactured to connect straight to the standard OEM downpipes, eliminating the need for extensive modifications or additional components. This means less time in the workshop and more time enjoying the enhanced riding experience your Triumph deserves.

Performance Benefits for Your Street Triple 675

When you upgrade to a Quill Performance Exhaust on your street triple 675, you’re investing in more than just aesthetics. The mandrel bent construction of our link pipes maintains a consistent internal diameter throughout each bend, preventing the restrictions found in crush-bent alternatives. This unrestricted flow allows exhaust gases to evacuate more efficiently, reducing back pressure and freeing up horsepower that would otherwise remain trapped within the engine’s potential.

The weight reduction compared to the standard exhaust system is immediately noticeable, particularly when cornering—a discipline where the Street Triple already demonstrates exceptional ability. By reducing unsprung and overall mass, the motorcycle responds more eagerly to rider input, sharpening the already impressive handling characteristics that have made this model a favourite among enthusiasts and professional testers alike.

The sound profile transforms too, unleashing the distinctive three-cylinder growl that these engines are renowned for, whilst remaining civilised enough for everyday use.

Quality Construction and Materials

Quill Performance Exhausts uses only premium grade stainless steel 304 in the construction of these link pipes. This material choice isn’t arbitrary—stainless 304 offers exceptional corrosion resistance, ensuring your exhaust system maintains its appearance and structural integrity throughout years of British weather exposure. The CNC mandrel bending process guarantees precision in every curve, with each pipe manufactured to exacting tolerances that ensure perfect fitment every time.

The welds are executed to aerospace standards, providing strength where it matters most whilst maintaining the clean, professional appearance you’d expect from a premium aftermarket component. This attention to detail extends throughout our entire product range, whether you’re looking at our Triumph Speed Triple 955i 2000 – 2004 exhaust systems or exploring options for other models in the Triumph lineup.

Installation and Fitment for the Street Triple 675

One of the most appreciated features of this exhaust system is its straightforward installation process. Designed as a direct replacement for the OEM components, the street triple 675 exhaust requires only basic mechanical skills and standard tools. The link pipes align precisely with the existing mounting points, and the included stainless steel straps provide secure, vibration-free attachment. The exhaust strap rubbers isolate any residual vibration, protecting both the exhaust system and your motorcycle’s frame from unnecessary stress.

For visual reference and installation guidance, we’ve produced a detailed video demonstration available on our YouTube channel at https://youtu.be/CiGUvYOfpQs. This resource walks you through the entire fitting process, offering practical tips and highlighting key steps to ensure your installation proceeds smoothly. Many customers complete the installation in under an hour, making this an ideal weekend project that delivers immediate, tangible results.

Compatible Models and Specifications

This exhaust system is specifically engineered for Triumph Street Triple 675 motorcycles manufactured between 2008 and 2013. It’s essential to verify your model year before ordering, as Triumph made various changes throughout the Street Triple’s production run. The system connects to standard OEM downpipes, meaning if you’ve already modified your downpipes, you may need to verify compatibility.

If you’re exploring exhaust options for other Triumph models, we also offer systems for bikes like the Triumph Tiger 1200 Explorer, demonstrating our comprehensive coverage of the Triumph range.

Frequently Asked Questions

Will this exhaust require remapping my street triple 675? While the exhaust will function with the standard ECU mapping, we recommend a professional remap or fuel controller to optimise the air-fuel ratio and extract maximum performance benefits from the reduced back pressure.

Does this system include silencers? This particular product focuses on the link pipe section. Please browse our complete range for compatible silencer options that complement these link pipes perfectly.

Is the stainless steel finish prone to discolouration? Grade 304 stainless steel offers excellent heat resistance, though some natural heat discolouration may occur near welds under extreme conditions—this is normal and doesn’t affect performance or structural integrity.

Can I fit this myself without professional help? Yes, the direct-fit design means most riders with basic mechanical aptitude and standard tools can complete the installation. Our video guide provides comprehensive support throughout the process.
