Hi guys

I hope you can help my out. I am trying to install this magnaflow system on my new truck and I can not get the muffler discontected!!!!

I lossened the clamp and the two tubes are so stuck togeather that I can not get them loose!! any ideas? I have not cut any of the tubing yet but think that is my next step.

HELPPPPP

You have to twist the mid-pipe, as it is notched. Take a good look at it and you will see what I am talking about. Also, you should cut just behind the stock muffler to get the assembly off, unless you have a lift. Good luck.

 

I just kicked my muffler, the whole unit went backward after a few kicks and damn near fell off...then I just worked it out from over and behind the axle, voila!

 

what do you mean by mid pipe?

I cut it off behond the muffler BUT the dam thing is still on. Hit it with a hammer and still can not get it apart.

Also the clamp seems to be weld on, is that correct?

help

 

just cut it off or try to make a slice into the old muffler where it is over top the pipe, its proly rusted on and yes they r a pain

 

Yes, the clamp on the end of the Y pipe is spot welded on, leave it that way.

He's right, it's probably rusted on...my truck has 12,000 miles on it, and it was "tough" to get off, but by no means hard to do or rusted on -- it does fit up in there a ways though, a good few inches so it took a few kicks/feet pushes to get mine out.

 

Thanks for your help guys.

I figured out what the hold up was.

There is a notch on the top of the pipe (from the muffler to the cat) that goes into a L shaped slot. You can not see it from the bottom but you can feel it. By the way I have an '05. You can pound on it all you want and it will never come off. You need to rotate the muffler (I unscrewed the hanger clamps to do so) then it came right out.

NOW, the hanger just behind the muffler seems to be about 1/2" to 1" off. I can not fully engage it into the rubber bushing which bothers me. Any ideas?

thanks again

Yea. I just took a screw driver and pried the lip of the pipe up far enough to allow the rivet to slip out. Then hammered it back down. Pretty soft. I also ditched the original clamp in favor of a stainless steel band clamp. The middle hanger just barely makes contact. Just enough for the flared tip to stick in the rubber. The front and back hangers seem to be in securely. If the whole assembly seems rock solid, I wouldn't worry too much about it. If it bugs you or the assembly seems weak there, a muffler shop could prolly re- position and re-weld that hanger to position better in the rubber. Check out my gallery and you'll probably see what yours looks like!

 

Thanks Raadlen!!

I thought it was just me.

I have emailed and called magna-suck 2 times now and nothing!!

They have a problem here with this design and it should be fixed!!!

I will let you know what happens

 

Bend the hanger on the "new" exhaust toward the isolator bushing...it's that easy.

 

how did you manage to do that while it is installed?

 

Thanks for asking that question. I just recieved my 16612 today and will be putting it on this weekend. All the advice and install experience found hear at f150online will sure come in handy. Had my new KR for 3 weeks now and can not wait to get the mods a-flowen.

 

I am really interested to know how you just bent it?????

 

If you follow the directions with the kit and not tighten the clamps until you have checked the fit for proper alignment, it easy to remove any of the section, take it to a bench and adjust the hanger arm. I tried putting the arm in a vice and then slipping an over sized piece of pipe over the arm and bending it using the pipe as leverage. That did not provide enough bend before the vice slipped. So what I found to work well was setting the hanger arm between two separated 2x4’s and hitting the middle of the arm with a ball-peen hammer until the sufficient amount of bend was derived. Due to the awkward shape of some of the kits pieces, a second set of hands would help to hold the tube or muffler to the side of the bench and out of harms way.

Hope that helps.
