| First off I want to say all the welds/piping look 10/10 from the outside. One thing I noticed though and I was curious if it effects performance is it is advertised to "taper down" from a 2.5" to 2.25" piping right by the turbo. Feeling on the inside of the weld it feels like a slightly smaller pipe was just welded against a slightly larger pipe causing a little bit of an edge to stick out on the inside. Kind of like going with larger throttle bodies and not quite opening/grinding away the intake back all the way on one side. I mean it is probably an 1/8". Does this effect performance? Should I take some effort to sand down this edge inside the piping before I install?
