Quick Time Performance (QTP) is the ultimate solution for enthusiasts who want the aggressive, roaring sound of a race exhaust combined with the quiet comfort of a factory muffler. QTP is famous for inventing and perfecting the electric exhaust cutout. By installing a QTP Aggressor pipe and high-torque electric valve into your exhaust system, you can instantly bypass your mufflers with the flip of a switch or the press of a wireless remote. Go from a quiet, neighborhood-friendly daily driver to a screaming, open-header race car in seconds.

• Exhaust Sound on Demand: Instantly toggle between a quiet, restrictive factory exhaust and a loud, straight-pipe roar from the driver's seat.

• High-Torque Electric Valves: Weather-proof, low-profile DC motors and butterfly valves designed to never leak or rattle under pressure.

• Complete Aggressor Kits: Vehicle-specific, bolt-on cutout kits available for modern muscle cars and trucks for easy installation.

• Wireless Control Available: Optional key fob remotes allow you to open or close your exhaust cutouts from outside the vehicle.

Unleash the true, uninhibited voice of your engine at the push of a button with a Quick Time Performance electric cutout.
