Milltek Non-Resonated Cat-Back exhaust system for Toyota GR86 - a direct factory replacement delivering aggressive full-throttle character and measurable performance. Hand-finished T304L stainless steel construction with burnt/blue titanium tips. Engineered for drivers seeking maximum sound intensity without drone in the mid-range, this system eliminates OE resonance chambers for a race-focused tone. Mandrel-bent T304L stainless steel throughout, CNC-formed burnt/blue titanium finisher tips. Direct OEM+ fitment using factory hanger points - no modification required. Non-resonated configuration optimized for closed-course and track use; street-legal in most jurisdictions but decibel output exceeds stock by approximately 8-12 dB under full throttle. All Milltek exhausts undergo dyno testing and acoustic validation before production release. • T304L stainless steel - hand-finished, mandrel-bent construction • Burnt/blue titanium finisher tips for heat-resistant aesthetics • Direct bolt-on fitment; uses OEM hangers • Non-resonated design - maximum tone character, no silencer packing • Track-focused sound profile; verify local noise regulations • Compatible with OEM TRD Rear Diffuser This non-resonated cat-back is engineered for enthusiasts prioritizing authentic tone and performance over refinement. Designed and manufactured in the UK with 40+ years of performance exhaust heritage. Tested at the Nurburgring.
