well sort of. the inlet of the muffler slipped off the end of the exhaust pipe today.!! everything was installed by me about 6000 miles ago. no offroading, hard use etc. kind of bummed. so i fixed it today. but since im not taking it off anytime soon, im going to have my buddy tig weld that inlet connection only next week.

 

You know the more I read about this the more I think that I am going to take this muffler in on Tuesday and have it welded in place. I think that will prevent any of the problems that I have read about.

 

I've had to tighten mine a few times. It starts to get loose after awhile and begins rattling right after startup. I've thought about getting it welded in a few spots as well.

 

I keep reading about the same people having problems with their mods and well me included , I am wondering is it worth it?

 

I had mine installed and welded by a muffler shop, no problems here.

 

How is the sound on your Mufflex 18's?
Where's a good place and a good price to pay?

well, i dont understand why it would be any differant than the stock system really. if anything you think it would be more solid due to less weight on the clamps etc. the rear clamps are bulletproof. no movement whatsoever.

 

I have always when working on exhaust set it up loose fit and when I have it all in place tighten it all a bit at a time and make sure none of the joints are under pressure so they will eventually come loose. Then when its all tight go get it good and hot like drive the **** out of it so the exhaust gets hot, hit the highway if your confident its on good then go home and let it cool and re tighten it all or the muffler is your cases. Never had a problem. Is that Mufflex a struggle to get into place or kinda maybe too easy? I have been considering it but I listened to my wife leave the other day and Ihad told her to hammer it. Stock exhaust is plenty good. Problem is every dodge that goes by makes the dogs get up and think MOMMY is home.

 

well. im not sure what happened exactly. i guess you could say im an "expert" shade tree mechanic. always work on my own stuff. front ends, brakes, etc. etc. i work in a trade for a living, (i.e. im not a desk jockey). so i know it was installed right is what im getting at.in fact i re torqued and checked everything about a month prior, just for the sake of it, to test for leaks etc.


i ended up having a friend, tig weld the bottom half to make sure it wont happen again. the mufflex is still the best way to go, considering they already have the hangers, and pre bent pipes already welded on. and if you were realy worried, have the inlet joint welded after its installed......

 

The only issue with having the joints welded after install is typically people will need to go to a shop for that. If that is the case the theory behind the Mufflex is out the window, that being a do it yourself system. Now the cost of the setup is not justified as those same people could have put a Magnaflow 14 in for a little less.

I went with it because if I can avoid someone else doing work on MY stuff it is a good thing. I have had ZERO issues with it after 14K on the muffler and not once having to re-tighten it.

One thing (and I note this in my how to) you really need an air compressor and air impact to do this. Do not fool your "strong" self. Doing this by hand is not as good as letting an impact hammer away at it. Of course I also mentioned the position of the clamp as being important in my how to.
