1. Remove the seat and right side fairing cover (with M109 insignia), behind the fuel tank. To remove the fairing, release the plastic peg on top by pushing the center inward and pulling the fairing upwards until the peg releases, remove the M6 button head bolt at the bottom of the fairing. Pull the fairing outward from the rear and upward near the plastic peg to release it. Once it is free from all plastic pegs pull it forward to release it from the bottom of the fuel tank. 2. Remove the right side cover above the exhaust-mounting bracket secured by one M6 button head bolt, retain bolt for later. Remove the chrome steel cover above the exhaust secured by two remaining bolts, (this chrome piece will no longer be used.) Remove the large left rear rubber grommet and flanged steel collar from this chrome piece, to do this press the steel collar out of the rubber grommet first, once the collar is removed push the rubber grommet out of the wire loop on the chrome piece, set aside for later use. 3. Locate the exhaust valve actuator solenoid and harness and disconnect the black 3-prong electrical connector and white 2-prong electrical connector. 4. Remove the socket head bolts securing exhaust flanges to cylinder heads, set these fasteners aside for later use in reassembly. Support the weight of the exhaust system and remove the 2, 8 mm bolts and one 8 mm nut securing the exhaust mounting bracket and exhaust assembly. Keep these fasteners for use later. Remove the stock exhaust system as one complete unit; this includes the stock exhaust bracket, headpipes and muffler, exhaust valve solenoid and cables. 5. The exhaust valve actuator solenoid must now be removed from the stock exhaust-mounting bracket. To perform this, loosen the two nuts securing each cable to the exhaust valve cable-mounting tab, Position A in Figure 1. Make enough slack in the cables so that the ends of the cables’ threaded sheath may be disengaged from the end of the mounting tab. Now remove the two M6 hex head bolts securing the solenoid to the stock exhaust bracket. The stock exhaust mounting bracket, headpipes and muffler and exhaust valve solenoid cables will not be used anymore with the your new Cobra Exhaust System. 6. Remove the dust cover from the solenoid to expose the rotating cam and cables. DO NOT TRY TO ROTATE THE CAM RELATIVE TO THE ACTUATOR SELENOID TO REMOVE THE CABLES; DOING SO MAY DAMAGE THE INTERNAL COMPONENTS OF THE SOLENOID. To remove the cables from the cam, use the slack in the cables obtained in Step 5 to disengage the cable barrels from the cam, see Figure 1. THE DUST COVER WILL NOT BE REINSTALLED. 7. Now prepare the exhaust valve actuator solenoid for reuse. SECURELY HOLD THE CAM TO PREVENT IT FROM ROTATING IN THE SOLENOID. WHILE PREVENTING THE CAM FROM ROTATING, remove the 10 – 32 flange bolt securing it, see Figure 2. Replace the cam with the Cobra supplied cam, BE SURE TO PREVENT THE CAM FROM ROTATING WHEN REINSTALLING THE BOLT, OTHERWISE DAMAGE MAY OCCUR TO THE SOLENOID , see Figure 3. Torque to factory specifications.

1. Make sure the bike is completely cool before starting the installation. Make sure the bike is secure on the side- stand or ideally a rear service stand. 2. Remove the lower fairing. 3. Unscrew the O 2 sensor. Remove the stock exhaust system at the rear canister support bracket and where it bolts to the engine. CAUTION -the stock exhaust is very heavy, be careful not to drop it! Also, be careful not to damage the engine sensor located near the front header pipe. 4. Pry out the old exhaust port gaskets and replace with new BMW OE (x4) exhaust port gaskets. Adab of grease will help hold the gaskets in place while you work. 5. Coat the exhaust studs and O 2 sensor threads with high temperature anti-seize compound. 6. Install the TBR headers into the exhaust ports making sure to get a good seat onto the exhaust port gaskets. Next, install the header nuts starting at the rear/outside stud and working your way forward on the outside set of studs. Once that is finished repeat along the inside set of studs. Tighten header nuts only finger tight at this point. 7. Be sure to coat the threads of the sensor with the included packet of hi-temp anti-seize. Install the O 2 sensor into the TBR headers. Turning the sensor in the counterclockwise direction a few times then screwing it clockwise to install will help make it easier to install and prevent the wire from binding. 8. Place a bead of the hi-temp sealant on the outside edge of the headers that goes into the canister. Slide the TBR canister onto the end of the S-bend pipe. Wipe off the excess sealant that will squeeze out. 9. Carefully slide the muffler clamp over the muffler. ( Note: The stainless steel canister clamp and the name badge on the canister come from the factory with a clear plastic protective film. Please remove this film before operation.) Attach it to the canister support bracket using the stock BMWhardware. Both tabs of the canister clamp should be located on the inside of the canister support bracket. Leave loose for the moment. 10. Make sure everything is lined up and start to evenly tighten up the header nuts to BMWfactory torque specification. Tighten the canister support hardware and install the springs as well. 11. Start the bike and check for leaks around the exhaust ports and the header/canister junction. 12. Reinstall the lower fairing

Start by loosening the rear cylinder down tube bolt located on the top of the old mufflers center collector in front of the rear tire. 2. Remove both of the front cylinder exhaust pipe head nuts and set them to the side for reuse with the MAC exhaust system. 3. Remove the right side passenger’s foot peg. Set the foot peg aside as you will need to reinstall it. 4. Remove the left side passenger’s foot peg. Set this foot peg aside as it will also need to be reinstalled. Note: When you remove this bolt the entire exhaust system will be loose and may fall. You will need to support the old exhaust at this point to keep from injuring yourself. Gently move the old exhaust system side to side to remove it from the rear cylinder down tube. Once the exhaust system is loose from the down tube remove the system from under the Virago. 5. Remove the bolt holding the rear brake pedal in place and remove the brake pedal from the motorcycle. Note: Set both the bolt and the pedal aside for reinstallation. 6. Next loosen the nut on the drivers right foot peg, 1 full turn to start with. Then remove the rear nut on the same foot peg. (Note: The bolt that this nut is on goes completely through the motorcycle. This is the center stand mounting bolt.) Now remove the front nut and set both aside for reuse with the MAC system. 7. Install the center stand stop bracket under the left passenger foot peg. Install this bracket with the 90° bend facing down and towards the rear tire. (Note: Center stand sop bracket in provided in the hardware kit and is approx. 5″ long with a 90° bend in it.) Adjust the bracket by one of the large bolts through the foot peg then through the bracket and then install it into the stock location. Put on one of the washers and a nut and snug up the nut. Lower the center stand until the center stand come in to contact with the bottom of the bracket. Tighten the nut until it will hold the bracket securely. 8. Install the rear down tube clamp onto the rear muffler and install the medium sized nut/bolt/washer onto the clamp just finger tight. 9. Install the (2) small bolts into the channel bracket on the rear muffler. Install the rear mounting bracket onto the two bolts and then install the washers and nuts onto each. Tighten the (2) nuts only slight amount so that you can slide the bracket front to rear to insure that when you install the bracket you position it properly. 10. Slide the rear pipe onto the rear down tube about ¼”to ¾” past the pre-cut slots on the rear muffler pipe. Slightly snug the clamp making sure that the position of the bolt and nut will not interfere with any moving parts. The final position of this bolt can hit the tire if it is not positioned properly. 11. Install the other large bolt into the right passenger and then through the top hole in the rear muffler mounting bracket. Insert the bolt into the stock location and install the washer and the nut. 12. Align the rear muffler and you can then tighten the nuts on the rear muffler mounting bracket, the cylinder down tube and the right side passenger foot peg.
13. Install the front muffler on the rear most mounting bolt of the drivers foot peg and put the stock nut back onto the bolt. Hand tighten the bolt only at this time. Note: Install the nut at this time is only to support the muffler and to insure that the pipe does not fall on the ground while you complete the next step. 14. Lift the front head pipe into position and start the stock nuts onto the studs. It is strongly recommended that you install new exhaust gasket at this time. Note: The new exhaust gaskets are not included in the kit but are available at your local Yamaha Dealer. After gaskets are installed hand tighten the front head pipe. 15. Remove the nut from the drivers foot peg bolt and reinstall the drivers foot peg. Note: Hand tighten only at this time. 16. Finish tightening the nuts on the front head pipes. (Install these nuts according to Yamaha’s Factory specifications.) Once the nuts are tightened on the head pipe you can then tighten the drivers foot peg nuts. 17. Reinstall the rear brake pedal and tighten the bolt that holds it on to factory specifications. 18. Check all of the bolts that you have installed of removed to insure that they are tight. 19. Start the motorcycle and check for any leaks. 20. You are finished with your new MAC Exhaust System.
