which highflow cat is best for rx8?
i just installed the b&b exhaust and midpipe w/resonator. i think it is way too loud for everyday driving. would having a highflow cat welded to the midpipe help reduce the noise and remove the cell? the b&b midpipe is 2.5 inches in diameter. is random tech the way to go? what about fit?
thanks
thanks
