cats or no cats
so i need a new cat and we all know that i cant use a uni-cat unless i jerry rig it. plus i wouldnt want to affect the flow by putting just 1 new cat. Anyways should i get the high flow y-pipe with cats or without? How will it sound without cats and whats the hp gain or loss with or without...- cali+Mocasho+
