I just bought a 2006 srx & i now notice a loud roaring noise while driving. What could be the cause of this sound?

Mechanic's Assistant: Thanks. Can you give me any more details about your issue?

It sounds like a loud exhaust, like a sports car shifting gears as it is zooming past

Hello

I'd start by checking all the exhaust joints - where the manifold joins the head and the down pipe joints just before the catylst - the best way to do this is to start the engine from cold and feel around each joint with your bare hands - feeling for exhuast gas blowing over your fingers - you'll have about 30 seconds before it all gets too hot.
