low pop out of exhaust i have a 94 transam with a stock lt1 with no cats and a thrush muffler dump, i changed spark plugs, spark plug wires not so long ago. anyway after i got my muffler installed it got like a very low tone low volume pop on idle only does it like every 4-5 seconds coming out of the dump. i have no check engine light on and the car runs great with no misses. is this something to worry about?
