HI Guys,I have a Cargraphics muff/200cat set up,medium sound.Since I did the k24/18's,I was thinking about getting a new muff/ 100 cat system in the future......BUT.....then I thought that this might be possible....To take the 200 cats out[one side has a flange and the other side would have to be cut] ,,,then find some good 100 cats about the same size and have a good muffler shop/welder weld them in???Yes ,I know thats not the Porsche way to do it....But it could be a whole lot cheaper.....Unless you want a good deal on my exhaust.......lol.......Thanks
