Granatelli Motor Sports vacuum/pressure controlled electronic exhaust cutout systems offer robust construction along with peak modern performance. They are built using CNC 6061 aircraft-quality aluminum bodies, stainless steel butterfly plates and blade shafts, stainless steel turndowns, high-temperature carbon steel drive gears, and a "smart chip" controlled motor with a "one touch" operation rock switch. Granatelli's complete electronic exhaust cutout systems include all hardware, gaskets, and proper wiring harnesses. They are available in different tubing diameters. Benefits: * No more needing to hold the switch, which usually damages internal gears * Unique V-band clamp allows turndowns to be rotated 360 degrees for ultimate adjustability * Polished turndowns offer 45-degree slanted discharge angle * High-torque DC gear reduction driven motor ensures total open and total closed operation every time

Summit Racing™ vacuum-actuated exhaust cutout kits are the ultimate cutouts for longevity and reliability. They are designed to withstand the harshest conditions imaginable underneath your car with bodies built from ceramic coated stainless steel that use a vacuum-actuated turbocharger wastegate actuator to open and close the blade. They function in high-heat environments and have been proven to work at temperatures as high as 2,000 degrees. Summit Racing™ kits work on any car that has vacuum assisted brakes. Even better, because they are vacuum-operated, there is no routing of wires and electric motors around hot exhaust pipes--just a simple vacuum line. Summit Racing™ vacuum-actuated exhaust cutout kits are of universal design and are built to perform and last. Features include: * Stainless steel bodies * 1,300 degree ceramic coating withstands heat and corrosion * Pneumatic turbocharger wastegate actuator withstands temperatures up to 2,000 * Stainless steel blade shafts * Stainless steel butterfly plates * Fits common 3-bolt 3 in. cutout flanges * Installs on any vehicle with vacuum-assisted braking * Eliminates wiring around exhaust pipes and cutouts * Requires Y-pipe cutout adapter or custom fabrication (as all cutouts do)

Go Fast Bits offers DV Plus Range with Direct-Fit Performance Diverters for a wide range of domestic and import vehicles. GFB's DV+ solution couldn't be simpler: keep what works and replace what doesn't. GFB expands the DV+ range with a direct-fit solution for the weak factory diverter valve used on many European vehicles. The solenoid coil itself from the factory-fitted valve is great—the ECU opens it faster than any pneumatic valve, so why replace it? The weak point, however, is the valve mechanism itself. GFB's DV+ solves this problem by replacing the valve parts with an anodized billet aluminum housing, fitted with a brass piston machined to exacting tolerances. The end result is sharper throttle response, lightning-fast valve actuation, and it will hold as much boost as you can throw at it. Other manufacturers' products involve replacing the entire system with a traditional pneumatic valve, or include a solenoid valve with the diverter. These approaches add unnecessary cost and additional parts (in some cases requiring long vacuum hose runs, mounting brackets, etc.). All these additional items result in a product that is slower, less responsive, more expensive, and takes longer to install. GFB's DV+ solution, on the other hand, is more responsive, less expensive, easier to install, and doesn't cause compressor surge/turbo flutter. Oh, and it doesn't require different springs or frequent re-builds, either. Order the model recommended for your vehicle.

Go Fast Bits offers DV Plus Diverter Valves with TMS (Turbo Management System) Advantage for a wide range of vehicles, particularly imports. GFB's DV+ solution couldn't be simpler—keep what works and replace what doesn't. GFB expands the DV+ range with a direct-fit solution for the weak factory diverter valve used on many European vehicles. The solenoid coil itself from the factory-fitted valve is great (the ECU opens it faster than any pneumatic valve so why replace it?)—but the weak point is the valve mechanism itself.

The end result is sharper throttle response, lightning-fast valve actuation, and it will hold as much boost as you can throw at it. Other manufacturers' products involve replacing the entire system with a traditional pneumatic valve, requiring long vacuum hose runs, additional parts for tapping into the intake manifold vacuum—plus either a different solenoid valve to actuate the pneumatic valve, or a ballast resistor to plug into the OE wiring loom. All these additional items result in a product that is slower, less responsive, more expensive and takes much longer to install. GFB's DV+ solution on the other hand is more responsive, less expensive, easier to install, and doesn't cause compressor surge/turbo flutter. Order the model recommended for your vehicle. Additional notes: * Retains the factory solenoid coil for seamless integration * Replaces plastic valve parts with metal for reliability and strength on chipped engines * Exclusive "pilot-actuated" valve mechanism for rapid response at high boost
