Hey.. Anyone experience after you rev your car up and left off you hear kinda of a "bearing" type sound coming either from the exhaust or from the engine itself. It sounds like more of a rattle when the rpms are dropping.

Question 2: When at full throttle it sounds like it is almost rattling up front. ONLY when it is around 6000rpm. mods are cats, borla.. jwt and intake tube.
Thanks for you help.
