If you want to go louder than the 2 big perforated pipe replacement..just do all 4 , so the 2 big + 2 small replacement with this method the Helmholtz chambers are still intact and functional and so you get no drone and it's louder and when downshifting you will hear small pops like back fire.
All this because it's not all about louder when it sounds like shit.. "exhaust sound quality" for our cars is important too ....
Sweet! I thought there was only 2 perforated pipes in the OEM muffler? What do you mean 2 big + 2 small? What exactly would I be replacing?

Thanks!
