The T5's I put on went on both sides like you say your left one did. Somethings not right either with that pipe or maybe your bracket is out of line on your frame. If you don't have a bent frame bracket and pipe is in exhaust port correctly, about have to be the pipe, IMHO. Man, some of this stuff can be frustrating as hell, especially for the money you put in pipes. You'll get it though, hang in there.
