while waiting to get the gear box back i figured ill do some other things to the car. got some project mu break pads, slotted and drilled rotors, weather shields, short shiftier, cusco coilovers, all new belts and gaskets and much more.
after taking the exhaust off i realised that one of the bolts of the cat had snapped and the flanges had been welded together, but the weld was broken which explains why the 34 was so loud.
