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.

1. This lowering method requires replacement rear suspension coupling components. This is a simple task, and is completely reversible. In addition, this kit provides for a 0″ setting, to easily return your bike to its original height. First, raise the rear tire off of the ground by the frame before you begin. Raise the motorcycle so no weight is applied to the rear wheel, allowing the rear wheel to spin freely. 2. Next, become familiar with your lowering kit. You’ll notice that there are two corners of the lowering component with two holes each, and one corner with a single hole. The corner with the single hole attaches to the swingarm (the bolt that is closest to the rear wheel). The only important part of this familiarization process, is to make sure that you get the part oriented in the correct position. The following photos will explain the purpose of the different holes, and also help you turn the part in the correct position before you install it. Look at the first photo on the next page: In the photo above, the part is positioned just as it should be, for installation on the left-hand side (kickstand side) of the motorcycle. A quick measurement will show that Dimension “A” on Side “A” should be shorter than Dimension “B” on Side “B”. If not, flip your part over (turn the face you are viewing away from you, but keep the corners with two holes on your left), and measure again. Next, study the photo below for info on the different heights you can set your bike to… When installed, Hole “0″ will place the bike at it’s original height. Placing the top bolt in Hole 1, and the bottom bolt in Hole 0, the bike will be lowered approximately ¾”. Placing the top bolt in Hole 1, and the bottom bolt in Hole 1, the bike will be lowered approximately 2″. Simple, eh? Now, let’s move on to installation. 3. Below is a photo of the factory suspension coupling as installed in your motorcycle. This photo was taken from the LH side of the bike, to keep things in perspective with our previous photos. Loosen the three bolts holding the original suspension coupling, and remove. Be aware that the rear wheel will drop down when the bolts are removed, just so there are no surprises!
