97 F350 CC LB Question
 

I recently bought a 7.3 bone stock and added a few things. I put a napa 6637 filter and a diamond eye 3" dp into 4" back. The exhaust was a pain to get on but we eventually did it. Was wondering if anybodies truck runs differently due to these mods? like the tranny seems to downshift slower or something?..is this normal or am i crazy?..thanks
