Anyone got any recommendations for good axel back or cat back exhaust that has a low or nonexistent highway drone? Thanks.

 

Lexus F-Sport exhaust

 

The lowest cabin noise/drone axle back for the 3is is the F-sport exhaust or Invidia Axle back.

lowest drone catback is Invidia and Tsudo.

Just remember catback exhaust is usually twice as loud as just an axle back.

 

I currently have the invidia q300 and would say that drone is really minimal. It is there but if you have light background music playing, you def wont notice.

 

Fsport exhaust has the lowest drone.

 

Add Tanabe axle back to the list

 

+1 for the Tanabe axle back.

 

F-Sport exhaust if you want the lowest drone.

 

i listened Tanabe on IS 250 - cant hear it at all. ****y exhaust

 

Tanabe sounds almost like stock lol waste of money IMO

 

enjoy da silence)

 

Little to no drone but with a noticeable improvement in throttle response. Exactly what I was looking for, and possibly the OP as well. To each their own. I'm sure performance is comparable to any of the other axle-back exhausts available.

 

so thats what ya need. On my opinion need to add midpipe
