How many catalytic converters does manual 5 speed have

Hello, it has a right and left converter - so, two. What diagnostic process led you to condemning the catalytic converters? Quite an expensive thing to engage -- no power and stalling are not symptoms I would usually attribute to catalytic converters at least on the surface. I would consider fuel trim issues - too much or too little fuel, too much or too little air. If you're suspecting an exhaust flow issue, you could have a muffler restriction still. But that's a low possibility. www.repairpal.com/repair-shops

Furthermore there are diagnostic test that can be performed to determine if the converters have failed... (live 02 sensor readings along with exhaust back pressure testing) It’d be to your best interest to have the appropriate testing performed - - full scan test along with any necessary subsequent testing.. Good luck!
