I have a 5" MBRP turbo back exhaust on my '04.

I recently bought a 5" MBRP delete pipe, to install and see how it sounds.

Any tips or tricks on getting this muffler off?????

I removed (and broke) the two clamps for the muffler, but it is on there good and not moving.

I tried spraying some penentrant spray and hitting it with a rubber mallet, with no luck.

I was hoping to save and salvage the muffler, in case the delete pipe does not sounds good. I really do not want to cut it off......should I just take it into a muffler shop and have them heat it up some?

Also, it looks like some hanging rods will have to be welded up to the delete pipe because there are 3 rods coming off the MBRP muffler and holding the rear half of the exhaust in place......any thoughts?

 

If you used crush clamps, good luck getting it back apart...

Might need an exhaust shop to get it apart without either cutting the pipe or crushing it to get the two apart...

 

What about an air chisel?

 

I guess also I do not want to drive to an exhaust shop when/if I am able to install the delete pipe myself, because nothing will be supporting the rear portion of the exhaust......I may as well just take the pipe in a let them do it.

Now, I wonder if most shops would be willing to remove the muffler and install the delete pipe?

 

Why would they care?
I have yet to have an exhaust shop not do work(on a diesel), about the only thing that gets some guys to stop is taking cats off a gas car, but for the most part as long as you dont say you got the work done there they dont care.

Really its not a big deal on a diesel, and actually in Texas the turbo counts as a muffling device Not sure about your state though....



About the only thing you can do from home, is cut slits down the side of the muffler/pipe junction, then pry up the slits to get the muffler off. An air chisel will probably just mess it up...

 

Well, hmmmmm......I thinking of just saying heck with the gentle method and to save time and money, I may just cut the muffler off!

I have a cordless reciprocating saw that would do the trick.....and I think it would only take a few minutes to cut the muffler off.

I could just cut the muffler flush off and then use a grinder and cut the muffler's end caps off........and hopefully slide the delete pipe into place.

I know this way I can atleast install the delete pipe and then limp to a local shop and have some hargers welded on and installed.

I just need to find some 5" clamps tomrrow, because I attempted to use a impact to remove the two clamps and both bolts just shredded right off....

 

That is really weird. When my cat and muffler fell off my stock exhaust clamps came off fine, heck I almost reused them and that was 4 year old factory exhaust. As far as getting it off it depends on the clamps you had on, but if they are like the factory ones it ain't coming off. A sawzalls will cut it really easy that's what I used, just a bit hard to cut straight As far as clamps, I never added any, there is only 2 holding all of my exhaust on and zero issues, the straight pipe is a lot lighter then the muffler.

 

Napa carries "preformed" band clamps, no more crush bending the pipes together

They're only about $7-10 a piece, but sure makes things easier when you want to change things up.

I have a habit of switching between my 5" straight pipe and stacks, so I built a "modular" setup so I can just switch between either in about 20-30minutes
Just unclamp the rear over the axle/tailpipe section, put the box/stacks in the bed and hook up the 90*/flexpipe to the downpipe/pipe section....
Preformed clamps are greatness.



If you can save the muffler somehow, you can still swap it back in if you need to for long trips to avoid the drone...

 

I use a 1-Ton Ratcheting Winch / "Come-A-Long" seems to work really good in pulling mufflers off. Remove clamp and hook come-a-long to frame and muffler. If you have a welding torch with a rose bud tip to heat up pipe helps too. Good Luck

 

sawzall....
