Stock exhaust pipe size at the cat
I am putting in a 3" DP welded into the stock exhaust. What is the pipe diameter between the cat and the resonator? I have the stock SLE exhaust from the DP back. What size adapter do I need to make the reduction?

We have no idea what size you have. What have you swapped? Do you have the SLE exhaust, or L67? Did the exhaust swap with the drivetrain? Are you aware deleting the Cat will make you lose some low-end torque and is illegal? And that any member here that turns you in will get a $250 reward? As well as any shop that notices it'* missing?
I can tell you with certainty you will not be happy with the loss of low-end torque. And your current mods don't spell cat outflowing.
(can you tell this is a pet peeve of mine? )

Paul, you flow alot more than Jared.
Every member with a mildly-modded L67 that ever removed a cat felt a reduction in low-end torque. Including another one just last week.
I felt it too for the short time I ran catless until my replacement arrived. VERY noticable.

The stock pipe size going into the cat is 2 1/2"
Mine now goes 3" all the way........... and I didn't lose any low end torque

Good deal. Go hi-flow. Can't remember who that was last week, but he ran for quite some time catless, then added one on our advice. He thanked us. Never sacrifice your low end. That'* what makes up somewhat for your heavier car. You gotta get it moving.

assume that the pipe leaving the cat is also 2 1/2" then that enters the resonator

The stock downpipe is a double walled pipe. 2 1/2" inside and 2 3/4" outside diameter. The biggest restriction in the stock downpipe is the stock flex connector. It'* inside opening necks down to 2".
The TOG'* braided connector is 2 3/4" inside diameter I believe.
