I have Corolla 86. Since last 2-3 months it is giving hallow sound through silenser (Although silenser & whole pipe is in good condition, no leakage of smoke).
Why such hallow sound comes from engine/exhaust?
cannot recommend fix without hearing ityou need to get car on the ramp and inspect it
plz check ur rear wheels berings
some time ur cylencer touched ur body inside of gear lever plz check it also.
