Vibrant

<h3>About Vibrant Performance</h3><p>Founded in 1997 and headquartered in Mississauga, Ontario, Vibrant Performance has grown from a focused sport compact exhaust specialist into what is widely recognized as the performance aftermarket's premier source for professional fabrication components. The brand operates as a division of Vibrant Power Inc., a Canadian company with roots stretching back to 1985 and a legacy of supplying exhaust and vibration-control components to OEM and aftermarket companies in more than 50 countries.</p><p>From the very beginning, Vibrant set out to serve builders, fabricators, and enthusiasts who demand more than off-the-shelf solutions. Whether the project is a dedicated drag car, a time-attack build, a street-driven turbo hatchback, or a fully custom fabrication, Vibrant's catalog — now spanning over 3,000 SKUs — is engineered to give professionals and enthusiasts alike the components they need to execute any vision with precision.</p><h3>Engineering &amp; Quality Standards</h3><p>Vibrant Performance holds ISO 9001:2015 certification, and the brand backs that credential with a rigorous in-house product testing program. State-of-the-art tools including FARO Arms, 3D laser scanners, and rapid-prototyping printers are used throughout the design and validation process, ensuring every component delivers consistent fitment and long-term durability in high-performance environments. This commitment to engineering excellence has earned Vibrant numerous private-label supply contracts with some of the world's leading OEM and aftermarket manufacturers.</p><h3>Signature Product Categories</h3><p>Vibrant's exhaust lineup is among the most comprehensive in the aftermarket. Their <a href="/974-vibrant-exhaust-resonator-5880">exhaust resonators</a> are a cornerstone of the brand, available in stainless steel, titanium, and aluminized steel to suit everything from street tuning to race applications. For builders constructing custom exhaust and induction systems from scratch, Vibrant's <a href="/974-vibrant-tubing-10173">tubing</a> — including mandrel bends in stainless steel and aluminum across a wide range of diameters — provides the foundation for clean, flow-efficient builds that professional fabricators rely on. Rounding out the performance side of the catalog, Vibrant's <a href="/974-vibrant-intercooler-core-14657">intercooler cores</a> use premium bar-and-plate construction with 6061 aluminum to deliver superior thermal efficiency compared to tube-and-fin designs, making them a go-to choice for forced induction builds that push into extreme power levels.</p><h3>A Brand Built for Builders</h3><p>Vibrant Performance has long been a fixture at major motorsport events — from the Pikes Peak International Hill Climb to grassroots drag and drift competitions — demonstrating that their components hold up where it matters most. With a deep distribution network, a continuously evolving product line, and an unwavering focus on the needs of professional fabricators and performance enthusiasts, Vibrant Performance remains one of the most trusted names in the custom build space.</p>

All I got was the donut. Sent an RMA request 5 days ago and still haven't received anything. Either the description is off or the wrong part was sent. I'm still waiting to hear from someone about this disappointment. 2/10/14
