Exhaust Shudder

[SLYLNE]

Hi All,

To keep it short, last week i noticed my clutch to be quite stiff and trouble getting the gears whilst stopped at the lights. So after taking the car to the mech, he said most likely the clutch needs to be replaced..so after pulling it apart, in went a excedy heavy duty.

All the gears work fine now, EXCEPT...while in 1st/2nd/3rd in low revs (1k-2.5k rpm) theres a shudder that vibrates through the front of the car to the rear...after 2500rpm its all smooth..it sounds like its coming from the exhaust but i may be wrong.

car is a s1 r33 gtst.

I will be taking the car back tmrw afternoon as it wasnt there before the clutch was changed.

Can anyone give me some insight as to what this might be? and what could be done?

Thanks in advance =)
