Jb4 + downpipes = bad??

Well I guess another sort of update. Maybe it’s just me... but now the car feels like it doesn’t pull as hard now with the downpipes installed. Right now just running jb4 map 2, intakes, and downpipes. Just me? Any idea why it might pull less?

Did you ever figure out the issue? I’m planning on running catted dp & JB4 on my 540i.
