Ever unbolted a Y-Piece from a main cat?
I have bought a Dyno-Max cat back system which I am considering installing myself. The only thing which puts me off slightly is unbolting the cat and existing y-piece. I don't relish the thought of tapping out broken bolt studs lying under my car if things start snapping.
So, question is - how are the main cat and Y-pipe joined together? Is it straightforward nuts/bolts passing through smooth flanges or are the end flanges threaded?
If the flanges are threaded or studs are used then I will probably get shop to do it and save my knuckles.
Thanks

dunno I've never had a 7 with fact. exhaust.
any of the ones I have had that still had the duals were connected to the cats with nuts and bolts.......
but I am curious how starting this thread to get the answer is easier then just say, looking under your car for 2 seconds?

thats the problem.....you're in the office.
and how is that being a jack *** - you have a break time correct? it only takes literally two seconds to glance under the car and see the flange...
its like me posting on here for someone to tell me the size of a bolt, when all I actually have to do is get a couple sockets and see which one fits - its a waste of time to an extent.......but you got your answer so meh.

On my TII, the OEM main cat has studs mounted in the flange at each end. Also, the flanges, themselves, are incorporated into the cat's housing, so that the studs are mounted in "blind" holes.
If yours are stripped or something, such that you can't get the nuts at the "y" pipe off, you might consider dropping the whole system and dragging it out from under the car. It's just about as easy to drop the whole system as it is to remove just one component.
