Well after a couple of months of having a lot of fun on the quads we have run into a problem. We went to ride last weekend and there was an "arrestor check". Guess what--my sons Banshee is missing arrestors. He has T-5 pipes, do we have to put Toomey spark arrestors on or is there something else we can do??? Ideas on cost?? We had no idea the arrestors were missing, when we bought the quad we were assured there was. Oh well, we have learned alot over the last 7 months!! Thanks in advance for advice and help!!! Nuts
