The best setup?
Was wondering which Magnaflow muffler could fit on the Porsche 928 S4 '88?
Also would an RMB with all stock res. be louder than installing that muffler?
Finally would the muffler with straight pipes to bypass the mid resonator sound nice?
RMB will be the loudest. Straight pipes to bypass cats or remove resonators completely?
I would go with RMB and the small resonators on your 88.
