Install muffler without impact wrench?

epborden · Oct 15, 2017

I am getting a new muffler delivered to me today and I expect to put it on. I have two questions for anyone who has done this:

Is the stock one difficult to get off?

Do you need an impact wrench to put the new one on (with clamps) or can I just use hand tools?

Stock one shouldn't be too bad. Penetrating oil will help.

Hands tools is fine. Just makes sure you put some ass behind the ratchet when you tighten the clamps to make sure they are tight so u don't have leaks

Shouldn't be a problem, I replaced my exhaust on my 2014 after 2 years and did it all with hand tools.

It should be easy.

Spray the clamp fasteners with penetrating oil, also give any rubber hangers a squirt of WD40 where the mounting rod goes through them.

If you have a long open end wrench or breaker bar with the right socket on it, use it to break loose the fasteners with slow and easy pressure. Sometimes it helps to plant a foot on the frame or differential to give you a bit more force and leverage.

One thing to remember...most aftermarket mufflers are shorter than the stock units so you may have to make up some pipe to bridge the gap.

Thank you all. Getting delivered today. It's a Mufflex DOD14M for those curious. Hope it goes well!

That's a direct fit bolt on.

Should be pretty straight forward--but definitely let the penetrating oil soak for a good long while even on a pretty new truck. That way they should turn instead of shearing.... :emotions122:

Breaker bar and PB Blaster and you're all set. If you're in the south with no road salt they won't be too bad.

x2 on PB blaster, if you are in a snow state with salt let it sit and the bolts will break free. Unless the entire bolt is glowing orange you shouldnt need a impact. Although I use my 18v impact for everything, I use it even to put in windshield washer fluid.

very easy install. i didnt even have to jack my truck up. used hammer against a 2x4 to help the old out and avoid damage as it was being stubborn

How do you like the DOD14M after the install? Is it very aggressive sounding? Any drone in the cab? Any leaks? I’m thinking of getting the same soon.
