I had 2 chamber flomasters on my 421 Lemans and hated them.I put Hushpowers on it with a H pipe and was night and day diff.Can now listen to the radio with no problem.Just put them on my 69 455 firebird with a X pipe and they are a touch louder but still can listen to the radio.Going to pull the X and replace with a H.FWIW,Tom
