My Coupe has developed a small cough when I blip the throttle and then quickly pull off. Not a full hot-rod cough, but similar. I've noticed this more since I put in a K&N filter, but that could just be because I've been intentionally revving and listening closely to the engine to hear the sound difference with the filter.

Anything to be concerned about?

It all has to do with timing. Wait until you install an after market exhaust.
