I second that as well...never heard of any problems with the dynomax, only the chokemasters...and yes mullinax i agree with ya too on magnaflows- gutless hollow sounding muffs that (i think i have said this before somewhere) remind me of an old chev beretta with a hole in the exhaust no matter what v8 motor they are on lol (ive seen and heard alot of those berettas dont ask me why lol)...Looking forward to the soundclips side by side! im dying to get mine in and hear them too!
