Anyone know what the stock cat and muffler flow?
i've owned a 1st gen (275k miles) ... 2nd gen (140k miles) and '03 (70k miles)
i've straight pipe all of 'em ...
recently gutted the cat and installed mbrp cat back straight thru muffler ...
first exhaust on any of 'em that has seemed to make a noticeable difference ... and yeah i am aware that it is the only one of the bunch that has a cat
anyone know what the stock exhaust flows?
