I was checking out IMF's website and saw this:

It says coming soon, I sent them a message through the site but I wasn't sure if anyone had any more info on it. I'm assuming it works with the factory manifolds, and replaces the center cat with a resonator pipe. I'm thinking about it for a future mod. However, will deleting the center cat cause a CEL? It looks like a similair setup in an article on lextreme. http://www.lextreme.com/greddysc.html
Just thought I would share.

 

Personally... I'd much prefer they make an X or H pipe and offer a true dual to the stock muffler attachment points. At the least this would most likely eliminate the issues of 95+ cars having to modify the exhaust for the long tubes. Then again most people putting LT's on a car are OK with better exhaust from the header back anyway
