Anyone know? and also what size is the stock piping going into the muffler?

Edit: Guess I should mention im asking about an 06 MCSS, I'm new to the LS4 and will probably have a ton of questions. I'll post pics once I get her washed.

Thanks for the piping size. Does anyone with the catback think they could get me a quick measure of the mufflers? I'm to cheap to buy the whole catback so just gonna order the mufflers and weld them on myself.

Thanks thats just what I was looking for. Length of the body, not overall I'm guesing? Also would you guys recommend center inlet/outlet, center/offset, or offset/offset?

Just measured the stock piping its actually 2" into the muffler and 2.25" for the tailpipes, just incase anyone needs the info later on.

There is no overall with this kit, the bent pipe is already welded to the muffler but there is enough room before the bends to accomodate the 2" inlet/outlet leads mufflers have. The Magnaflow kit has center/center mufflers.

Ok I got it now. I think I'll order the offset inlet mufflers to get as close to the stocl position as I can.

Anyone running a single in/dual out muffler? If so how's it sound and what specs on the muffler?

I really like the sound of the muffler delete cars.

Those do sound sweet, but this car will be my DD so it has to stay some what tame. Maybe I'll just hack the stockers off until the magnaflows get here.
