1996 camaro V6 3.8 smoking

Question

i have a 96 camaro V6 3.8 auto that has a smoking problem. it has a cold air intake, dual exhaust and no cat. thats all the mods i know about since i bought it used. if i change the oil or add stp to oil it wont smoke as much for awhile until the oil breaks down some. i never have to add oil which makes me think its not oil burning but why will it stop a little if i change oil... Hmmm. anyway if im idleing at a light and then go its like a cloud behind me. the car runs great, no misfire, plenty of power, im afraid to tune it up because it runs so good. i was thinking that maybe it could be the exhaust system not having enough force to expell the harmfull pollution into our ozone. it dosent seem to feel like a lot of force coming from exhaust. im not real concerned about it because it runs so well, its just a little embarrassing. any help or ideas would be great. thanks all
