I assume your custom system has two pipes (2")into a cat, then one larger pipe (2.5") leaving the cat, which goes into the glasspack. If your blockage is in the glasspack, then why not just replace it with a high performance muffler? In doing that, you essentially have the same setup as the MM300 exhaust, which uses a Bosal rear muffler (sorry, but I haven't been able to find a number on it for you - maybe MM will tell you).
If your blockage is in the cat, then why not just replace it and leave the rest alone?
As you know, my system is the MM300 and it has two (2") pipes into a cat, then one (2.5")pipe that leads to a Bosal rear muffler. Nothing magic. I don't understand why MM gets the money they do for it, but whatever. It's probably louder than some folks might like, but I honestly don't mind it at all. In fact, I like it. It's agressive sounding, but not obnoxious at all. Quite quiet unless I'm really winding it out.
Bottom line is that IF you were happy with the system before you had this trouble, then I'd deal with the blockage, either in the cat or the glasspack, and leave the rest alone, unless there's another compelling reason to change it. If you weren't happy with it, then I'd look at re-engineering it.
Let us know what you do.
