On my 99 NBS Silverado it has the 4.3 I am starting to drag through the Y pipe right where it runs under the trans. It is the lowest part on the truck. Was under there the other night to find out the trans cross member is flush with the frame which I thought was odd since I keep seeing raised trans cross members. Is there anything that can be done to raise the Y pipe? I looks like it doesn't have much room to move up before sitting against the trans. It doesn't look like true duals can be done in fear of heating up my trans lines that run down the driver side frame rail and then over to the trans. Any help would be appreciated.
