Cat back replaces everything past the catalytic converters.

Axel back is really just replacement resonators and tailpipes

If I did an axel back I would nuke the suitcase and put in an x pipe.

But why not just nuke the suitcase first for cheap and see how you like the sound before spending any more money? This is what I will be doing and another member has already done it and got a great sound with no drone

 

Is there anymore info on installing the x-pipe in and all? A simple DIY with pics or just some info to help me see and understand what I need to do and order.

 

You need to be able to weld.

 

Ok thats no problem... What does everyone think that deleting the muffler and installing an x-pipe and leaving stock resonators on would do? Deepen the sound and make it a bit louder? Would it be too loud like the resonator delete kit from mufflex? Any input would be awesome. I am just on the fence because I do not want to install this and it sound like a rice burner or just be obnoxious and raspy....

 

There's a video clip with sound by someone who has a Hemi in one of the threads of the suitcase delete with X pipe

 

I saw a video with the mufflex muffler delete but that deleted the resonators and not the suitcase I believe.

Do cat back

 

Thanks Wash. But that is on the HEMI... Guess no one has done it on the PentaStar yet....

 

YouTube video!
Here's my 2013 RT with K&N CAI and Mufflex rear delete. It still has the suitcase. It's loud, can drone, has set off car alarms and has turned heads when Trans kicks down. I even had another Durango owner pull along side and ask what exhaust and loved the sound. My neighbors may disagree. That said it makes me smile every time I drive it. If the link doesn't work search youtube for Durango mufflex and it should be first video. Still image is of a long empty straight cars on right.
