I have a 2011 is350 and drove an F for the 1st time today. I love the way it sounded so my question is if I upgrade my exhaust to the F Sport exhaust will it sound the same? I never had upgraded exhaust in my life and don't want the rice rocket sound. Thanks

 

No your car wont sound like an ISF, simply because you dont have a V8. Although the sound that the F Sport exhaust gives your IS may seem too loud for some folks, it by no means sounds like a "rice rocket."

You will get a deeper growl (compared to stock) when you start your car and during normal driving.
