What's the possibility of my exhaust being blocked? I realise my exhaust gas temperatures are pretty high and flow seems pretty weak when I place my hand against exhaust tips. Car works perfect otherwise - vtec and all. It seems as though however performance is getting weaker and weaker. My engine as well as the exhaust are still stock.

I had the honey cone material in the cat removed a couple of years ago. Is it possible for the resonator/rear silencer to become block over a 12 year period?

1992 Honda Prelude Vtec.

Thanks.
