Default GS 350 getting loud

My 07 GS has suddenly become much louder on mildly aggressive acceleration. It kind of sounds like how a carburated engine sounds like with the air cleaner removed. Any ideas?

Sounds like an exhaust leak, take it to the muffler shop and have them test for leaks especially at the mid pipe.

I was thinking that might be the problem but I started telling myself that was too simple. lol. I am going to take your advice and head to the muffler place. Thanks.

Its common on our cars, especially on awd. The tin covering on the mid pipe should be removed as it collects water and slowly rots out the mid pipe exhaust.
