Simply replace the mufflers. A good shop should be able to do this. The rpi exhaust is nice to look at but is fairly loud. I modified my system to replace the mufflers with straight pipes for racing[ You can loudly hear my PTE turbo whistling even at idle,very loud. When I use it on the street I put the mufflers back on. Good luck
