sorry i dont mean to use harsh letters. i was under my car changing my oil a couple days ago and ive noticed b4 that the exhaust pipe between the driver side manifold to the y pipe, for maybe a foot and half, is a little crunched up like it was bottomed out on. i didnt think it was too much but i do get like 13 mpg and am sure it was that but it didnt look that bad, until i looked under there from the front and holy shit! in one part its crunched down to maybe a 1/4 of what it should be. so im gonna take a sawzall and chop it out and replace it with some new pipe. so would it be ok to not weld it in? i dont have much access to a welder but i can get a connector(?) to tighten the ends together. it doesnt need to last more than a couple years for i am getting an ls1 someday.
