big bear
+1y
yea, thats not an easy size to match up man. i run dual magnaflows on my v8 noma, yes i know thats smaller than a 454 lol ...., but its got a real distinct tone, like you know something is there but not sure to what degree. haha .anyway, my point is that yea when i mash on the gas she comes alive and it sounds mean, but not annoying. since i havent swapped gearing in my rearend yet, i run at a high rpm and it still not overboard. very mellow. but as i stated, i understand you have a 454 and its alot more motor. i am going to run same duals on my dually when i get it one day. jus purely opinion.
