New and looking for answers

Hi all! I own a 2006 Pontiac G6 GTP hard top convertible. I recently started having a sound almost like a motorcycle upon acceleration (sorry, it's hard to describe it) and it increases with acceleration and decreases as I slow down, there is no vibration, is not running hot. Has new tires and recent front end alignment. Any help would be greatly appreciated! Thank you!

Is it possibly a hole in your exhaust pipe? Not sure what type of motorcycle sound you're referring to though. Engine still running good, but just louder?

Sounds like your flex pipe has blown out.

if it decreases when you slow down, and not when you let off the acceleration it could possibly be a wheel bearing going bad.
