I began using muffled tuned pipes in the late Seventies. Some engines throttle well with them, others are a little cranky, depending upon how short you run the pipe/how much you load the engine. I ran OS and Webra engines mostly back then and I tended to run my pipes a tad long, for more pull going uphill.
With that said, there was usually at least a slight stumble when going on the pipe, making throttling non linear. I've never had a set up where you couldn't sense the engine go on the pipe. This would not be good for 3D flying/throttling at all.
I don't mind it when other people's opinions differ from mine. After all, I know that mine is correct and if other opinions differ, they are simply wrong.
