  • If you're worried about boost creep. just port and increase the size of the waste port/flapper... Not a big deal

  • took my cat off in my 85 monte carlo 305, and she sounds a little raspy but when I get some mufflers should sounds nice, also switch up to an x pipe soon.

  • 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.

  • The biggest benefit of a cat delete is the reduced risk of it clogging and overheating the exhaust and cylinder with backed up heat

  • 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.

  • If you add a blow-off valve, you can blow off the excess pressure on the intake side. Cheaper than a new turbo.

  • 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!

  • Cool vid!!! It’s hard to make an apples to apples comparison, Jew to mapping, but really, higher exhaust flow when tuned in gonna make more power. Love the Chanel 👌🏻👊🏻

  • Not that I would ever do this myself ***cough*cough*** but I have "heard" you can remove the cat, beat all the innards out, then put it back on the car. If the cat goes bad, that may help a few people that do not have the $800 replacement cost (for my car).

  • Great test. I think you need a bigger Boost set up so that we can see the real difference. Or maybe just go naturally aspirated. I'm pretty sure though if you have a exhaust manifold catalytic converter a header works better.

  • 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.
