Asked by Aug 21, 2016 at 02:09 PM about the 2017 Subaru Legacy 2.5i

Question type: Car Customization

I want to hear a nice boxer rumble, but don't want to affect anything on a brand new car.

A 4" muffler will make it sound like the rice rocket it is.


Lol, dont you have something better to do? Being factory back to the axle, it won't sound rice, just a mellow rumble when on the gas pedal. IMO, boxer engines sound sweet, but now even a WRX or STI are too quiet from the factory. I have a Legacy, a midsized family sedan. 175hp, AWD, 30mpg and the safest car on the road. That's less rice than an ecoboost Mustang or any $70k European sedan with their computerized exhaust notes.

I guess if you like the sound of a flat 4 or flat 6, go for it. Me? I am into the rumble of classic V-8s and a 4 or 6 banger will never sound as good as a V-8. Also...No, I don't have anything better to do. LOL
