Well hello this is my first post. Just bought an 05 636 and when i ease off the throttle my exhaust makes a sputtering noise. I have no idea what it could be? it sounds fine when i accelerate and decel its only when i give it just a little.
Yeah its aftermarket not sure of the brand cant find a name on it its like a sputtering sound and it happens whenever i ease off the throttle right at that point where i start to accelerate but not totally closed.
