Your supposed to use perforated pipe through the center and repack with wire wool. That looks like it`ll` bang like a drum. I think you will have to open it up again and weld perforated pipe between the inlet and outlet and pack with wire wool before welding back together. Other than that it looks quite neat.

It has a plate about three inches from the inlet, where the original internals were, then behind the plate it has about six inches of drilled holes, a butt load of them. Then stainless steel was wrapped around it; then packed with fiberglass.. I should have taken pictures. It was copied from one of the members on this site. Sounds really nice.

600 is alot of money for that
600 is alot of money for that
What would be a fair price?
That is a good question??? I'm hoping I dont have to do anything.. I have just ridden it once since I've modified, and it ran like before, just louder. I would like to say a little better, but that might be just because it was louder as i shifted through the gears. I should check my plugs I guess after a few more rides. I have not removed the cat from the mid pipe and dont know if I need to??? More testing required I guess/suppose?
