As i said before, if you get a piece of pipe about 3 inches long that fits snug into the muffler youre set. It does involve a weld though. You weld the 3 inch pipe to header, at the same time heating the muffler end with a flame then push muffler onto the new pipe. get your self a sexy stainless clamp and your done. To cover the weld you can get a small heatshield. im gonna use some heat tape once i get a spare $50 to cover the weld and the blue bits on header. should look sexy as.
