ugh man i have a 95 gsx with 190K on the body and between 2-3 rpm my driver seat and passenger seat shaker very very bad....after i pass 3000rpm it goes away and once i let off the gas the car rides on backpressure while it shakes again...I just put in new 3" downpipe with a dump tube and it made it lot worse?...im lost the...catback and everything else is pretty tight....driveshaft maybe? thanks
