Prepare Vehicle for Service This installation should be performed by a professional installer. If you do not have proper tools, safety equipment, and training you run the risk of injuring yourself or damaging your car. The use of a lift is strongly recommended to perform this installation. It is highly recommended to spray various nuts and bolts in the factory exhaust with a penetrant such as PB Blaster or WD40 and allow it to soak for a few hours to avoid seized or broken bolts. Step 1: Raise Vehicle Securely support the vehicle on a lift or 4 jack stands with at least 24 inches of clearance from the frame rail to the ground. Step 2: Disconnect Battery Remove the negative battery cable to battery nut and separate the cable from the battery. Step 3: Remove Spark Plugs Remove the spark plug wires and spark plugs to avoid damaging them during installation (5/8” spark plug socket). Step 4: Disconnect O2 Sensors from Engine Wiring Harness Disconnect the primary and secondary O2 sensors from the engine wiring harness. The primary connectors can be found near the rear of the cylinder heads on the engine. Primary O2 sensor connectors are black, secondary O2 sensor connectors are gray and are best reached from under the vehicle. OEM Exhaust Removal Step 1: Remove Dipstick Tube The dipstick tube must be removed to get the manifold out and the headers in. Remove the bolt securing the tube to the head and pull upward on the tube to unseat the bottom end from the oil pan (15mm socket). Step 1: Disconnect Factory Mid-Pipe Loosen the nuts on the slip over clamps attaching the mid-pipe to the cat-pipe (15mm deep well socket). Slide the clamps over the midpipe (passender side) and over the manifold pipe (driver side) exposing the butt joint between the two sections of the OE exhaust. Step 2: Disconnect Steering Shaft at Rack Remove the bolt that secures the steering shaft to the rack (11mm socket on extension). Compress the steering shaft to disengage it from the rack and push it off to the side. DO NOT ROTATE THE STEERING SHAFT – DAMAGE CAN RESULT.

Step 3: Remove Exhaust Manifolds Remove the six bolts securing each exhaust manifold to the head (13mm socket and short extension). Remove the manifolds and gaskets from the vehicle. The manifolds are best removed out the bottom. Inspect the head surface and carefully clean it with a gasket scraper if needed. Take care not to gouge or scratch the sealing surface of the aluminum head. Step 3: Remove O2 Sensors from Factory Exhaust Remove the primary and secondary O2 sensors from the factory exhaust (22mm wrench). Retain the O2 sensors for use in your Pfadt Power Products exhaust.

Pfadt Tri-Y Header Installation Procedure Step 1: Install O2 Sensor Extensions Connect the primary O2 sensor extensions to the engine wiring harness. Do not connect the actual O2 sensors at this time. Step 2: Install Driver Side Header Install the driver side header from the bottom of the vehicle. Take care not to damage the clutch or brake lines running along the firewall with the header flange during installation. Hang the header in place and move to the top side of the vehicle. Re-install the OE header gasket using the provided header bolts. The OE gaskets must be installed in the correct orientation to avoid blocking any spark plug holes, the orientation is clearly marked on the gasket. DO NOT use any sort of gasket sealer on the header gasket. O2 sensor and catalytic converter failure may result. Start the two header bolts that are on the tight holes (the front bolt and one of the center bolts). Start the other 4 header bolts and snug the flange to the cylinder head. Step 3: Install Passenger Side Header Repeat the procedure from the driver’s side header. Step 4: Install O2 Sensors Apply a thin coat of anti-seize to the threads on all O2 sensors. Install one primary O2 sensor (black connectors) in each header (22mm wrench). It does not matter whether you install the factory O2 sensor in the forward or rear bung in the passenger side header. If a wide-band O2 sensor will be used, install it in the extra bung in the passenger side header. If no wide-band sensor will be used, apply anti-seize to the threads of the provided bung plug and install it in the extra bung (10mm hex bit socket). If applicable, connect the primary O2 sensors to the extensions installed previously and tuck the wires out of the way of the headers. It is convenient to zip-tie the O2 wires to the various fluid lines running along the tunnel to keep them away from the headers. If the Pfadt Tri-Y exhaust system has catalytic converters, install the secondary O2 sensors (gray connectors) in the bungs in the connector pipes (22mm wrench). If the exhaust system does not have catalytic converters you will no longer need the secondary O2 sensors.

Step 7: Install Exhaust Connector Pipes Using a chisel and hammer, remove the nub (see photo) on the driver’s side of the OE mid-pipe

Loosen the 4 bolts holding the undercar brace across the tunnel (15mm socket). This allows the mid-pipe to hang a bit lower and facilitates the installation of the connector pipes. Slide the OEM clamps onto the appropriate sections of header or mid-pipe. Leave the clamps loose. Align the Connector Pipe and Mid-pipe 2.5inch sections and slide the OEM clamps into place, leave the clamps loose. NOTE: If you have an aftermarket Mid-pipe the uses and “slip over” connection, re-use or replace the clamps used with your current Mid-pipe, not the OEM “butt-joint” clamp. Align the V-band flanges on the headers with the flanges on the connector pipe and install the V-band clamps. Tighten the nuts far enough to ensure the flanges won’t slip out of the clamps, but leave them fairly loose for now (13mm deep well socket). Connect the secondary O2 sensors to the factory wiring harness. Re-torque the tunnel brace bolts. Step 8: Torque Header Bolts Torque the header bolts at first pass to 11 ft-lbs (15 N-m). Begin with the center two bolts and alternate from side to side, working toward the outside bolts. Torque them at final pass to 18 ft-lbs (25 N-m), again starting with the center bolts and alternating from side to side as you work outward toward the ends of the flange (13mm socket, various extensions). Step 9: Torque Fasteners Torque the OEM clamps between the connector pipes and the OE midpipe to 32 ft-lbs (44 N-m) (15mm deep well socket).

Torque the V-band clamps to 12 ft-lbs (16 N-m) (13 mm deep well socket).

Step 10: Reinstall Dipstick Tube Re-install the dipstick tube from where it was removed earlier in the installation. (15mm socket). Step 10: Reinstall Steering Shaft Align the flats on the steering shaft joint with the flats on the rack input shaft and slip the joint together. Using thread retaining compound on the bolt, re-install the retaining bolt and torque (11mm socket). Step 11: Reinstall Spark Plugs Reinstall the spark plugs and plug wires. If you have difficulty getting any spark plugs started in the holes, refer to the gasket installation step to ensure the header gaskets are not partially covering any of the plug holes. Step 12: Check for Leaks Double check that all fasteners have been tightened, wiring is not dangling on headers, spilled oil is wiped off headers, and that there is adequate clearance between the headers and any other components. Start the car and check for exhaust leaks, oil leaks, or coolant leaks. Congratulations, you have successfully installed your new Pfadt Power Products headers and mid-pipe and are now ready to reap the rewards of a carefully engineered exhaust system!

NOTE: To prevent thread galling, do not use a high-speed driver such as an impact gun on the V-band clamp nuts. Only tighten by hand and torque to spec.

Warranty and Use Restrictions Our warranty covers the workmanship and materials of the headers and mid-pipe for the original purchaser on the original vehicle of installation for five years. Headers and mid-pipes that are sold to another person or removed and installed on another car are excluded. Catalytic converters are covered for one year. Pfadt is not responsible for premature failure of a catalytic converter due to tuning/tuning related issues or other negligence on the part of the installer or end user. If you have a catalytic converter failure outside the limits of the warranty, we will ONLY charge you for the replacement of the cats and provide you with a free connector-pipe for up to 5 years from original date of purchase. Pfadt reserves the right to replace individual components. All Pfadt headers are for off-road use only. These exhaust systems are intended for use on “racing vehicles” (i.e. a competition vehicle used exclusively for competition on closed-course circuits) and do not require an exemption or Executive Order from CARB to be sold in California for such purpose. However, such parts are prohibited from use on many state’s public roads, including California, even if occasionally used “off-road.”
