Here a ticking noise by trans area and also hear what sounds to be an exhaust leak under load between 1800 and 2200 rpms. Have longtubes with same brand bbk hi flow pipe. Had car in the air today and it was ticking away by trans and header area but do not see or hear exhaust leaking. Listened by oil pan and by cylinder heads and dont hear noise. Car has bad throwout bearing clacking around but dont think thats the ticking or could it possibly just traveling?
