Yes, this is normal. All exhaust is routed to one tailpipe when running under 3000 rpm (or thereabouts) to keep things quieter. There is a flap that opens above that threshold to allow more flow under acceleration/higher speeds.
lol yep it is normal i sugest against a K&N fiter or any fiters you spray oil on because the oil can kill your MAF sensor
