Switching cat's and test pipes on A.W.E. dp's?
I want to take the cat's out and put the test pipes in to see performance gains (if any) and sound differences (if any).
Is it hard to do? How long does it take? Any special tools needed? Do you need a lift?

You will gain 20-30whp (on a stg 3 car not sure on stg 2 car but it will be significant)
and exhaust will get louder. You don't need a lift if you don't mind working on your back. Just make sure you have a set of jack stands.

CEL will show up after 100 miles.
The CEL won't cause any performance losses or problems, it will just be annoying. There is a fix for this in the tech section.
I didn't even put my rear o2s back in. They are just strapped to my tranny
I had to have a muffler shop do mine as well since I couldn't get test pipes from AutoSpeed. I just had the cats cut off and a new 3" pipe welded on.
