Looking for cheap source for above in GTA for my son's car (1.8L SOHC) which failed e-test. Heard universal ones are available for as little as $100 or so. Any suggestions?
Also, is there a lot of cut to fit and/or welding involved re installation of universal type? Existing (aftermarket by prior owner) cat has fore and aft flanges but those might have been welded to extension pipes welded to actual cat. Just took a quick peek under car, haven't got it up the ramps yet.
