To just remove the CAT and install the CAT delete you do not have to remove the side panel ...

It's tight but once loose you can lower then rotate the muffler to slip out the old and slip in the new. Hardest part is reinstalling the springs.

Be advised that there is a secondary CAT in the muffler itself and the muffler is not the greatest quality build so a good percentage (myself included) who installed a CAT delete on the stock can quickly blew out the internal welds.

The white honeycomb disk in this cut open stock muffler is the secondary CAT ...

wow....didn't know that....so I'm deleting half of it ....hmmmm….now I have to rethink this...all of the people that put the delete on have said a little torque could be had....but maybe a little rich smell during cold enrichment then alright....I just want to have torque to have fun within speed limit....anything helps...

@Orangeman you are correct, you can drop it from below, but you have to get the SS pretty high up there, I couldn't do that at first safely with just my floor jack and stands. Plus removing the side gives you lots of room to work with and I've gotten pretty good at taking them off for various projects.

He's not trying to remove the muffler .. for that you must remove the side panel ... just the CAT pipe ....

The CAT pipe, once unbolted from the manifold and the muffler springs removed, easily removes from the top without jacking anything up....

Hey Orangeman I think I can get it removed pretty easy but replacing the cat delete what was the best way for you....bolting up to manifold first and then springs or install into muffler and install springs and then bolt to manifold.....thanks for your info sir....just looking for proper procedure and shortcuts/tricks from someone who has battled through it before …..thanks

Not that it is the only or best way but I put the delete pipe in place and just started the manifold bolts so I still had some play, then rotated the muffler back in place, installed the muffler springs, then torqued down the manifold bolts.

Good luck, not a lot of room down there and getting those springs back on can get frustrating...

Couldn't get my MC exhaust spring tool at an angle with enough leverage to reinstall so used a long loop of 550 cord around the spring then around a pry-bar against the motor mount ...

It's a graphite ring/doughnut and is reused ......

When you install it on the delete pipe note the locating notch .........

I've seen a video of how to pull it off, couldn't find all of the bolts so went looking. Slingmods always has excellent videos, so started there, and they show pulling the muffler out, but they don't pull the whole side panel off, just loosen the front to make room :

This may or may not work for you.

Oh, I remember now, wasn't a video, was the Welter exhaust install that had good pics of it : 2.5″ WP Dual Boosted | Welter Performance

Hope that helps

.Orangeman, when you refer to blowing out the internal welds, are you talking about the secondary cat welds or the welds on the muffler itself? I don't care if the secondary cat blows out, but I don't want to damage the muffler and have to replace it.... Can the secondary cat be drilled out?
