When coasting or accelerating pass the 2400 - 2800 rpm range. the exhaust resonance cause the whole cabin to vibrate, and i'm developing more rattly noises!!
I recently removed 1 (baffles were fecked) centre muffler and it seems to be even more pronounced now with remaining 1 centre box and 1 rear muffler. Only de-cat, otherwise standard exhaust.
I was thinking of removing the other 1 centre box leaving only the backbox for less backpressure. and more sound. but am i right to say that by doin so, the resonance will be even worse??
also can worn mufflers cause resonance/vibrations to be felt in the cabin??
