Hey guys , so I currently have an mbrp race catback . I want the car louder. How much louder would the car get keeping stock headers and installing high flow cats ?
I know a cat delete would most likely be louder but how much louder? I'm kind of trying to avoid this option. But I do want it loud
And last would installing high-flow cats on the stock headers require a tune?
