Exhaust Leak
Also, one thing I feel I should also mention is (always done this ever since I got the O/R Y put on), if I'm on the highway doing say 65-70 or just really at any highway speed, if I let off of the throttle completely it makes a really loud fluttering noise. Sounds almost exactly like an exhaust brake and I can hear something squeaking and ratting in the process. I would be willing to bet it's coming from my exhaust. Car also seems like it hesitates a little at some points under light-mild acceleration, but really don't notice any lack in performance.
So, does it sound like I may have some exhaust leakage going on here or something else?
Any help is appreciated
