I just istalled some flowmaster mufflers. I am getting a slight rough idle. Had the car on the dyno and gained 4hp and 9-10 tq. Has anyone had this problem? Was thinking of switching back, but don't want to lose gain. Tried to disconnect the battery to see if that worked. Also noticed that my rpm's fall slow once I have my foot off the gas. Need a little help before I go back with stock.:confused:
