Hey guys new to the forum..looking at magnaflow exhaust to put on my truck just wondering what size muffler you guys would recommend? Biggest magma flow muffler was 20 and I have a 31" just wondering if that's a good investment ?

 

all kinda depends on what sound, tone, loudness, drone, etc. you're going for...

 

14" isnt loud enough in my opinion, I have it on my truck and wish I would have gone more aggressive.
