Yesterday I had a Magnaflow mufler installed on my SuperCrew and I'm satisfied with its sound and no loss of low rpm torque. But I was very surprise at its small size! It is about a 1/3 of what my original OAM muffler was, which was pretty big; about 3 feet in length. Do you think this is right or did they put the wrong kind in and got screwed?

 

It's fine; you can put any size on that you want. Most aftermarket mufflers are smaller than the factory garbage can.

 

Thanks for your reply! I checked with another friend and his truck muffler is also much smaller than the stock one.
