Just ordered a new MBRP cat-back system. I've been under the Jeep and can't get the stock muffler out of the rubber bushings. The mound is like an arrow that goes in but doesn't come out.

Is there a trick to removing the muffler and pipes or do I just need I give it more muscle?

 

WD-40 and some muscles

 

Just jerk it harder, lube also helps...

 

Flowmaster has a video on installing their JK muffler. Check it out...

Channel locks to press em out, I had same prob

 

I used vaseline and a crowbar to pry them out. Major PITA though

 

This and a rubber mallet , and a small pry bar helps as well.

 

A lot of grease and large channel locks did it for me. Don't be gentle!

 

I used a pry bar on the rubber bushing and popped it off the hanger.
