Just a shot in the dark, but the exhaust note makes me wonder if your timing
belt has slipped. If so, catastrophic failure may be in the near future
unless the belt is replaced. Retarded valve timing results in an odd
"hollow" exhaust sound. If that doesn't describe the exhaust then "never
mind." But... how long / many miles since the last timing belt change?
