Making My Magnaflow Louder?

I have had my Magnaflow muffler and exhaust redone to 2.5" from the header back for about a year now. My system sounds good at higher RPM's I just wish it had a bit more of a rumble at idle and at lower RPM's. I know that I have heard some magnaflow mufflers on some jeeps and they seem louder. I have the shortest oval case that you can get. Im really an exhaust fanatic, and I really like to hear my jeep in the mornings when I am letting it warm up (sounds childish, I know but it makes me happy) Any ideas on how I can get it to be a bit louder?
Currently I have 2.5" piping from the header to the muffler, Hi flow cat, 2.5" piping from the the muffler to the tip, the tip is a 2.5" inlet and 3" outlet and ends right before my rear shackle for my leaf springs.

Run a 4" round body magnaflow muffler. They are more aggressive. That's what I run. You can hear mine in the exhaust sound clip thread that's a sticky at the top mine is the first video

I'd rather now run one of these...I ran a similar style from Dynomax (the bullet)
and it was too raspy.
Was thinking if I get a longer tip...stainless tip, might make the tone a bit better.

A turn down after the muffler will make it deeper. I have found turn downs in general make the exhaust deeper since the sound bounces off the ground.

Thought about this....just don't want to add any more vibrations to my jeep than it already has.... hmmmm thinking about making it exit out the side somehow....

A longer tip won't do anything, If you want to make it louder and stick with a oval muffler get one with a shorter body then offset the length difference with 2.5" pipe

Longer tip will change the tone of the exhaust. right now. I am using a VERY short stainless double rolled tip, so adding more tip for it to go through, it will change the exhaust note. won't make it louder, just change the tone.

Also, I have the shortest oval muffler they make.

If I'm on mobile I can assume he's not in the US since I can't see his location and it's not illegal and thus doesn't break any JF rules.
