TTI exhaust too loud

I have a TTI H-pipe system. After the collector, there's the H-Pipe section, then the muffler location... The only place I can see where there's any room is in the very back. Am I missing something?:read2:

You may have to make "some adjustments" to your H-pipe to make it work but it makes a lot of difference in the sound. I`ve got the glass-pack / mufflers on my Barracuda. I`ll try to get a couple pictures for you.
