Does removein.....i mean if your kitty falls off going down the road and you are slow in finding a replacement doe that affect your MPG?
Thanks guys
Oh, and if i have to take my truck in for a warranty repair do i need to put a kity in there first?

Did not see any MPG improvement, But anytime you let air flow 200% better. It's always better for the truck. But I really did not calculate when I removed mine.

Live in Texas (Bexar County), That crap does not fly down here NOTE: yes it can void warranty if not installed.......................................
I hollowed it out and bolted it back on, Just for the pipe. You will here plenty of guys here say NO NO NO why would you do that, It's worth more than buying a piece of pipe. Not to me it's not. We all do things are own way

As far as sound, You will hear your turbo quit a bit more.

Didn't help my MPG's at all, neither did the 4" exhaust.

I gained almost 2 mpg by killing the kitty and deleting the muffler. The secret is after you do it. to keep your foot out of the go pedal. No matter how badazz it sounds. Trust me i know its difficult

a farmer electrician friend told me he just took it off, banged it against a rock and a bunch of stuff fell out so he put it back on and his truck has been running better ever since. I like that idea, tapp it a bit to get the build up inside to fall out then reinstall it. Hey, still factory right? But what do you do about the o2 sensors? Does the sd have two or just one, humm...gotta look

thanks Dave. I would have expected a small gain but 2mpg is pretty good

I don't suppose there is a way they can tell if one is careful to put it back properly. Seems like a much safer mod than adding a chip or tuner
