Are there any more choices other than the Tanabe, Apex'i, and J2 axleback exhaust? If not I'll have to go custom.
I can't believe no one replied. I too would also like to add a little sound to my 2012. Not sure if I want to cut up the stock exhaust or not though.
I think the reason no one replied cause no one has done it! Nor even consider it! I recall seeing a video on YouTube of prius exhaust mod. I suggest refraining from any drivetrain, emission, hybrid modifications your warranty is a contract, you uphold your end, toyota uphold there end in accordance to what written in the warranty!
