i just noticed that the stock exhaust (2004) is kinda restrictive, like 2"
even while idling, the stream coming out looks like its going 30 miles per hour (if i can even judge the speed of a gas )
comparatively, my grand am's stock exhaust at idle just seeps outward slowly.
soo, has anyone relieved the pressure after the snail or no?
