98 Integra: Change in engine sound

Hi

My 98 Acura Integra w/ 120k miles on it has pretty much been trouble-
free. But recently  I noticed the engine noise changes to a throaty
growl when I step hard on the accelerator like when you would do on a
highway ramp or merging into a faster lane. Its hard to describe the
noise but if the normal engine noise is
"rrrrrrrrrrrrrrrrrrr"
then the changed one is more like
"RHRHRHRHRHRH"

:-)

I should mention that my last oil-change was a bit delayed, after
about 7500 miles instead of the usual 3500miles, not sure if that
caused it.

I fear to take it to the  dealer’s service center in case they tell me
to just replace the engine.
Short of that, any clues what might be wrong, or where I should start
looking?

Thanks in advance

    When I modified the intake of my Honda, it made a growling sound under
    hard acceleration.  Not much to go on, but it might be worthwhile to
    check the intake and air filter housing for leaks, especially if the
    air filter was changed with your last oil change.

    Start looking underneath. Is any part of the exhaust system starting to
    fall off?

    Exhaust leak or if you had the intake apart to change the filter it may
    not be on correctly. Both can make a big change in engine sound levels.
    Also look around the engine and trans areas for any part that could be
    touching a body panel or the firewall. Doesn’t take much to allow sound
    to travel.
