I have a squealing too , it started when I noticed my belt needed to be changed . So i replaced both belts (serpentine and alternator ) and it started making a louder noise out of nowhere I'm thinking either water pump or maybe a bearing or one of the pulleys but not sure
Bad exhaust not the muffler but more of where it's attached at the engine. Anyone recommend any good exhaust systems that are good brand and cheap ? Also thinking of swapping headers what would you recommend for that ? Anything would help thanks
