well being a part time muffler maker, i do like the good glass packs on the old hot rods and in line 6s and you realy need no larget then 1 3/4 inch pipe to get that old sound. i like the way the blue streak glasspacks sound and last. best bang for the buck in my eyes. i dont use any on my cars because i make a muffler here that i like the sound of, but its not old school by any means
. cant beat old school on an old ride.
