    Did he measured the inner diameter of the exhaust manifold and the test pipe and making sure they have same inner diameter?

    Leave the cat on, put an electric exhaust dump before the cat controlled by the boost controller. So when you mall crawling you don't have to deal with the smell, and you bypass the cat, muffler and 10' of pipe when its time to go.

    Cat removal on a K Series is by far the best way to free up power. However on other 2.0 NA engines I’ve had from other manufacturers (Renault), the Decat had a negative effect, due to the scavenging of the engine.

    Your mig gun cable should be kept as straight as possible to prevent bird nest. And you didn’t wear a jacket which is not good as mig welding produces several different lights, infrared, ultraviolet, and there’s another I can’t think of and it produces radiation, not wearing proper ppe is rather reckless.

    Ah, the good old test pipe. Something I've done on nearly every Honda I've ever owned, much to my neighbor's dismay. I eventually got smart and just did header back exhausts but before I had money, cat deletes with a ghetto ass test pipe rigged in it's place was the ticket baby. Who cares if it made more power, it sounded like it did and that's all that mattered to 19yr old me.

    Grind the wastegate hole. This was always a common mod for Mitsubishi turbos with internal wastegates. The flapper is plenty big enough to cover a larger hole, but the wastegate hole itself wasn't big enough to bypass enough exhaust gas, hence it goes through the turbine itself, increasing your boost. Shouldn't take more than a couple hours or so to pull the turbine housing off and grind that sucker. I saw you were making about 235 and I guessed you'd make at least 250 with the cat bypass. Cat bypasses are no joke. If you're trying to make power at the track, a cat bypass is a no-brainer. PS- I love all of Zach's content. He's great, and he's taught me a lot. Dude knows what the hell he's doing!

    Hot Rod Magazine did a similar test several years ago at West Tech Dyno and conclude very little difference between Cat and No-Cat. The length of the pipe from the engine to the back of the car was way more of a factor, along with mufflers.

    Sure beats the hp you get with bad cats. Remember to replace catalytic converters at 150k to 200k miles or if you're vehicle ever puts oil or coolant out of the tail pipe. A blown ring or head gasket sucks, but it sucks worse when you have to turn around and do a second rebuild because a bad catalytic converter toasted the engine.
