MagnaFlow Direct-Fit Catalytic Converters

MagnaFlow direct-fit catalytic converters are designed for easy bolt-on installation for the professional installer. Welding, cutting, and tube-bending equipment are not required. These cats feature a ribbed body that minimizes expansion and distortion when the converters heat up. The ribs form a channel that protects the cushioning mat from direct exposure to exhaust gases, and they hold the ceramic catalyst in proper alignment. MagnaFlow converters use a monolithic honeycomb catalyst; the ceramic coating is designed for maximum flow and surface area, and the coating method is strictly controlled to maintain exact specifications. Improper coating could result in flow restrictions or an emissions test failure. These converters are designed to exact OE specifications and are available for the most popular vehicle makes and models.

APR Turbo Muffler Delete Pipes

The APR turbo muffler delete pipes are designed to replace the factory muffler with a straight, uninterrupted piece. The delete pipes are CNC-machined from billet aluminum and anodized black. To ensure proper sealing, APR's engineers took a two-part approach. A Viton® seal is included and forms a seal between the base of the muffler housing and the new piece. With the seal in place and the outer flange installed, the muffler delete tube screws into place, forming a full, uninterrupted path for airflow. For a smooth, turbulence free, and leak-proof path for airflow existing in your turbo, install one of the APR turbo muffler delete pipes. Additional features include: * Removes factory turbo muffler * 2-piece design with gasket eliminates leaks and factory tolerance issues * Enhanced turbo sound * Faster spool * Better power delivery

Go Fast Bits DV Plus Diverter Valves with TMS Advantage

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. So GFB's DV+ solves this problem by replacing just 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, 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
