Ok heres the deal. I was looking for a 3000gt vr-4 94 model. Surprisingly there was one with only 64000 miles and in really near mint condition (car was hit on drivers side but fixed and you cant even tell) and hes selling it for $8000!!!!!!! I test drive the car and theres this sound duk duk duk duk duk and sounds like its coming from the engine. I check and everything seemed ok but couldnt tell because it was at night time then i noticed that only one of the 2 exhaust worked. Can you guys tell me what the problem can be??
