Anybody have the dimensions/drawing of one, or have one laying around? Would like to get a Summit 5" exhaust and make it a cat-back system.

You do know that a 5" system with the stock intermediate pipe (cat pipe) won't make any more power than a 4" system right?

IMO - put a 4" catback on, then put on a 5" tailpipe/tip. Nobody can tell it's not a 5" system unless they crawl under your truck.

PS - if you REALLY want a blueprint for it, I can make one for you.

I really don't want to take the cat off, for warranty work concerns if they arrive. Also, I figured the 5" would make a nicer rumble than 4". And I don't know of anybody that has an exhaust set-up like it.
