silverline muffle question.

[Crystal Creek]

I have a full 4" turbo back with no Kitty. I was in my buddies truck the other day. His exhaust is cut off right past the cab. He still has a muffler but no kitty as well. It sounds AWESOME!!! So I went to do this on my truck. I moved the muffle up a few feet and installed the turndown. Well I noticed the inside of the muffler. It has little cup like things that I guess absorb sound. It looks like the muffler can be used either way. The cups are currently "catching" the exhaust flow. If I turn the muffle around, will the sound be louder?? I dont want to straigt pipe the truck yet as it is a work truck. Sould I turn the muffler around??? Thanks for the help.

Straight pipe it - I'm cut off at back of cab waiting to hook up the stacks - No kitty, no muff - Sounds fine on the drive - no one even knows til my right foot digs in....THEN ITS BAD A$$

+1 straight pipe it. 4" turbo back completely un-restricted. the turbo sounds great and when you do dig with the right foot its like a rocket taking off! DOOO IT....DO IT.....

I was looking up info last night and found you can turn the muffler around and make it louder.
