Use a 3/4 in crow foot, same size as 19 mm, there times I use a 5/8 in for 16 mm and 1/2 for 13 mm in a pinch.
Leading evidence: 'Use 5/8 in' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Disconnect oxygen sensors' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

You'll need to disconnect the O2 sensors to remove the cats.

My set goes up to 18mm and skips to 22mm, none of the parts stores had a 19mm...

I got quite a bit of use of my exterior �E-Z outs� when taking my exhaust apart.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I guess that depends on how much of the car your wanting to take apart. I can take the factory mufflers out in 10 minutes as long as it’s on a hoist, don’t even need to take the wheels. The crossover cat section takes 5 mins to remove.
Not really sure what your trying to accomplish?
Probably, but there wouldn't be much point. The system comes apart pretty easily and is designed to be fairly modular, so it seems simpler to take out in pieces. Remove the mufflers first, and then the cats. You'll need to disconnect the O2 sensors to remove the cats.
I'm pulling the motor.
Bumper, heat shields and wheels are off. If I could leave it intact and drop it with out undoing everything it would save time, no?
Easiest to drop the engine with the entire exhaust attached to the engine. Then remove the 3 bolts on each side at the the header to cat flange, and the clamp at the engine carrier. This will leave the exhaust in 2 large pieces. No need to break them down further than that.
In my experience, having just removed mine this past winter, I don't think it will save you any time. I've found that trying to wrestle assemblies like this is false economy and in the end, faster to just take it apart and make it easy on you. Its a simple system with few parts, so any savings of time would be very small.
The flip side is that then you are dealing with two heavy awkward shaped components. I find it easier to remove the mufflers and catalytic converters, leaving the headers on the engine. For me, taking the exhaust system out as one piece would be a false economy.
I got quite a bit of use of my exterior �E-Z outs� when taking my exhaust apart. My suggestion would be to save yourself time and aggravation and just cut the ones that don�t easily unscrew - you may have come to this conclusion already. But all new stainless steel hardware and be liberal with the high temp (copper based) anti-seize !
All apart now and will be upgrading it's hardware. Im am have difficulty getting the steering lines apart and am waiting on a couple of 19mm crows foot attachment I had to order. My set goes up to 18mm and skips to 22mm, none of the parts stores had a 19mm...
Thanks!
