So I recently acquired a 1989 325i coupe manual 215k
I also own a 1990 325i sedan manual 160k
Finally got my coupe!!!!
So after driving both back to back I started to realize something,the sound and engine noise north of the firewall are definitely more noticeable on my new 1989 coupe???
Of course I thought it was exhaust noise resonating in the cabin,it does not seem to be?
When I accelerate my 90 the noise from the rear of the car is what I notice most. The engine smoothly accelerates and u hear the muted Rpms go up and down
When I accelerate the 89 I can definitely hear more engine noise, mind you it is not some crazy straight pipe off the exhaust manifold noise but it is noticeable.
I opened the hood looked under the cars exhaust and manifolds while revving both, sounds different deeper tone maybe?
Insulation differences? Maybe?
I am concerned because I am not sure if coupe engine is on its last leg?
Thoughts?
