Help. Problem with weird exhaust noise/rattle
It started with a metallic vibration that I would hear towards the rear of the car. Once this stopped, all of a sudden I had a weird exhaust note at random RPM's and (maybe im just paranoid) but slight power loss. Its an 08 335i coupe, with Catless DP's and straight piped after that so there is no butterfly valve. Its also boosting normal (17psi on map 5) or atleast according to the boost on fuel hijacking it is. I havent had a chance to put it up on the lift yet to check for any exhaust leaks but im not an expert on this car anyways so I want opinions. Anyone have a clue? ps- it idles smooth, runs smooth, no white smoke.
