About QTP – Quick Time Performance

Founded in 2002 and headquartered in Hawthorne, New Jersey, Quick Time Performance (QTP) has spent more than two decades earning its place as one of the most respected names in the performance exhaust aftermarket. QTP is widely credited as the inventor of the original electric exhaust cutout — a claim backed by over 20 years of continuous design, engineering, and in-house manufacturing. Every product that leaves the QTP facility is built with purpose: from flow testing and precision modeling to the careful selection of premium-grade materials.

QTP's lineup serves an impressively broad range of enthusiasts, from classic hot rod and muscle car builders to off-road truck owners, light-duty pickup drivers, and import performance fans. Whether the goal is squeezing out extra horsepower on the dragstrip or simply dialing in the right exhaust note for a weekend cruise, QTP has engineered a solution for it.

The QTEC Electric Exhaust Cutout – QTP's Signature Innovation

At the heart of the QTP catalog is the legendary QTEC — the brand's flagship line of electric exhaust cut-outs. These electrically controlled valves are constructed with CNC-machined 6061 aircraft-grade aluminum bodies, stainless steel butterfly plates and shafts, and high-torque DC gear-driven motors with high-temperature steel gears. Available for single or dual exhaust configurations in diameters ranging from 2.25" to 5.00", the QTEC line also includes a low-profile oval variant designed for vehicles with limited ground clearance. The result is a system that can go from whisper-quiet street driving to full wide-open exhaust at the flip of a switch — without ever crawling under the vehicle.

To complement the cutout valves, QTP also offers complete exhaust system kits under product families like the Screamer Twintronic and Eliminator lines, giving builders a cohesive, performance-matched solution from the headers back. For those routing or replacing mid-system hardware, QTP's exhaust intermediate pipes — including the Aggressor cutout pipe systems — provide the precision-fit connections that performance builds demand.

Finishing Touches: Tips and Controls

QTP also pays attention to the details that define a finished build. Their line of exhaust tail pipe tips includes universal adjustable turn-down tips designed to pair seamlessly with QTEC cutouts, available in multiple diameters to match common exhaust tubing sizes. And because the entire QTEC system is electrically operated, QTP rounds out the package with purpose-built toggle switches — including mini weathertight connector kits — so installers have everything needed for a clean, reliable interior-mounted control setup.

Made in the USA, Built for Performance

QTP's commitment to domestic manufacturing and rigorous quality control sets it apart in a market flooded with imitations. Each cutout is designed and built in-house, and the brand backs every product with the confidence that comes from two decades of proven performance. For car enthusiasts who refuse to settle for a copy when the original is available, QTP remains the definitive choice in electric exhaust management.
