So i bought jba catless pipes for a few reasons,
1) a laugh at the rpm act
2) louder, and it is at idle
3) g8 board said itll lower my ET....

Drove it 55 miles there with catted pipes on. Let the car cool off for 75 minutes to start my 1st of 3 runs with a 40 minute break after after each, averaged 13.32

Took an hr to switch to catless b.c i had to clamp them to fit the x pipe. Ran 3 more with 40 in between each run... averaged 13.30 lololol

cars full bolt on, no engine tune - just cat sensor delete in the settings

damn between the weight savings and flow. I would have thought it worth a little more.

I mean there are plenty of factory 500+ HP cars that have full emissions equipment, I think the common theory that cats are "too restrictive" is just a myth. And the exhaust smells better too.
