I have 38 k miles on my 07 , I have so far installed a Greddy TIC ypipe back exhaust system and Altered Atmosphere test pipes. So anyways I pushed the car out of a turn hard on 4th gear only took it to about 5k rpms and I felt like a bit of a jerk as if the clutch may have slipped for a split second. then shifted to 5th and it jerked again . I only get the effect when I push the car hard I suppose because this morning was the first time I felt it and it only happened that one time when I pushed it hard on the highway. Under city street driving I dont get that .

So do you guys think my clutch is slipping ?

 

Oh and my RPMs dropped slightly aswell when this happened.

 

^^ If you feel "jerking" when shifting, it's not "clutch slipping." Clutch slipping would be about the opposite (lack of grab).

It sounds as though you are experiencing a delayed clutch-engagement (with a consequent "grab").

Maybe something is "hanging"?
