Dude. 2 eyes, 2 ears, 1 mouth. The hole only gets deeper when you dig.

At best, an aftermarket muffler saves a few lbs. Maybe even 10-15. I've seen carbon fiber variants of car mufflers that save up to 20.

You'll never even see the savings from that.

EDIT: Are you getting your data from magazine articles? I'm seriously trying to help you here... Magazine articles are almost always biased toward their sponsors, so the data is hardly ever irrefutable. In fact, it's almost always easily proven either to be incorrect wholly, or insufficient to draw a proper conclusion.

Just check around the 2 years worth of posts here... (Hint Hint) you'll see several of the sort have been debunked.

Ok thanks for trying to help. I'm probably off on the exact weight of the muffler but i know deleting exhaust parts is a way to lighten most cars, long as you don't mess with emissions

When we took the rear muffler and piping off of my friends GMC sierra V6 it weighed over 55 pounds , new muffler he put on weighed 10 pounds. Maybe they don'tweigh 100 pounds but the point is the stock mufflers on most trucks are heeeeeavy
