If you want that sound, you need to make some big changes which are not inexpensive.
A 906/RSR sounds like that due to camshaft profile, compression ratio, headers and megaphones. Racing exhausts like that work from 5K+ to 8K+ and simply kill power below 4K.
Not good at for any street cars.
Don't shoot yourself in the foot by installing a pair of race mufflers without a balance tube; stick to a dual-in/dual-out sport muffler of choice.
Naturally, JMHO.
