Ok, this picture is not a finished product. I was having some ideas about building some slip on pipes and the first thing I did was slide an 18" piece of 1-3/4" over the headers and take it around the block. I didn't notice much drop in my low end torque and I love the sound but I just want to know if this is harmful for my engine? Will it deteriorate any quicker with open exhaust? I had Bubs on it before, so I rejetted (cant remember what too, 45 & 12x?) and i have the cold air intake (K&N's) Any suggestions before I start to actually make a finished set of open pipes?
