If its in the truck in your sig do the straight H pipe. Guys at the muffler shop can install it from around 40-50 dollars.. I installed my own with a kit from Summit and a 110 volt mig welder. It will help.... Just make sure you put it in the right place. I believe you can use a crayon and mark a line down the length of the pipe. Turn it on and watch the pipe, the point where it melts first is the area to cross it. If you leave it on for a while eventually it will all melt. Some one else probably knows a better way.

Oh ya, thats nice IC2!
