Just to manage expectations, the cabin is fairly well insulated, so don't expect a deafening tone even with an aftermarket exhaust. My car sounds like absolute freaking thunder at WOT, but it's nowhere near that inside, it is loud but you can still hear the passenger all right [as they scream and beg you to slow down].

One quick tip, try folding the rear seatback down for more volume and better exhaust sound inside the car.
