Glen E., I tried to get some 40 series for my 292 the other day and every place in town had 2 1/4" and larger. And I live in a big town! 2 1/4" is much too big for my needs (I'm running 1 3/4" dual). So, decided to go with glasspacks. Sounds awesome! Not too loud at idle/slower speeds but, when you get on the gas it sounds cool. Yeah they'll wear out before Flowmasters but, at only $20 I can afford to swap 'em out. Another thing, I've read that Flowmasters aren't so masterful at flowing. I guess when tests were run they were one of the worst. Read that a couple different places. Could be propaganda, who knows.
