Looking to buy a new manifold as I keep having flexi issue’s and I just want the problem solved permanently. So I just wondered if anyone has put the predator kam racing manifold, pure motorsports manifold, or ktec racing manifold on their 197? And if so what’s your experience with it been like? Also would there be any chance of failing mot on emissions with either of these manifolds? I currently have an aftermarket manifold on the car, its not a toyo because it isn’t stainless steel so I’m not sure what it is really.
