Ordere'd Silicone tubes from SBP, cut the stock muffler and extended the tube all the way to the back, no welding involved, used the silicone tubing to attached everything back together, Ended where I wanted it to be just need to paint and fabricate some mounts to hold the muffler back there.
Next thing is to fab up another extension tubing for my daughters trailer so the fumes ends behind the trailer.
Where can I get longer the silicone tubings, went to home depot and my local harddware shop, nobody seems to know where to get it. I wanted to use the tubing to extend the exhaust tip all the way to the back of the trailer when I have the trailer attached.
EDIT: I was starring at the pictures I uploaded and I realized I need to cut those cables ..
