Dinan Valved Cat-Back Exhaust - 2020-2026 Toyota GR Supra 3.0
Upgrade the sound, performance, and driving experience of your Toyota GR Supra with the Dinan Valved Cat-Back Exhaust System for 2020–2026 Toyota GR Supra 3.0. Designed for enthusiasts who demand premium quality and refined sound, this Dinan exhaust delivers a deep, rich, and aggressive tone while maintaining full factory valve functionality for complete control over exhaust volume.
Engineered using factory mounting points and cut locations, this system installs with precise OEM-like fitment while offering major improvements in flow, construction quality, and overall appearance. The exhaust is built from 100% T304 stainless steel with TIG-welded construction for long-term durability and corrosion resistance.
For improved performance and reduced restriction, the original dual-pipe layout is replaced with a larger free-flowing single-pipe design, increasing exhaust flow while reducing weight. The system routes into a specially tuned muffler that minimizes drone while preserving the signature low, aggressive Dinan exhaust note.
The system retains factory valve control, allowing the exhaust to switch between a quiet, refined tone when closed and a louder, high-flow performance sound when open. Massive 4.5-inch (114.3mm) black ceramic coated exhaust tips with laser-engraved Dinan branding complete the aggressive rear appearance.
This cat-back exhaust provides improved sound, reduced weight, and measurable performance gains without sacrificing comfort or drivability.
