today @ this car lot i was revving this GT with after market exhaust (donno what kind) i was revving it cuz they were about to leave so there was no time for a test drive today. anyhow if it was idling and you gradualy pressed the pedal then it would go up no prob...loud untill about 45 or so then the exhaust gets really quiet so wtf? but what really gets me is if its idling and you slam the pedal it boggs down for a second; it hesitates...then it really kicks in and goes like it should...but is that hesitation from dirty injectors or from them putting ****ty gas in it? or both or neither? any ideas?

was it warmed up. sometimes with the rpm range and depending on the type of exhaust the tons change I had magnaflow x with mac catback and it was louder under 2 and over 3500 and it was between the two

im mostly worried about the hesitation, i mean its like the whole car completely shut off for like 1 second. No, it wasnt warmed up and as i keep thinking of what you just said im thinkin more and more about how it being warmed up would have been diffrent haha.

I know for what ever reason when it is cold out and my car is not warm I have to let it warm up for about 5 mins which i do anyways but then there is no hesitation.
