ok so I have the vibrant header and downpipe with high flow cat and 2.5 catback with an 18 inch resonator and magnaflow muffler. well my tune is too rich which has clogged the cat. if i take a crow bar to the cat and gut it out how much difference is it gonna make it sound? will the resonator and muffler help keep it quiet or is it gonna be insane loud?

 

it will be a little raspy. not too bad tho im sure. my ZZP header and DP with the stock resonator and borla muffler aint too bad. WOT sounds damn good tho.
