REAL RESULTS.. Is it really worth running NO CATALYTIC CONVERTER? We test it on our big power SUPRA.

100 cell is a tiny restriction, a normal cat is way more restrictive

655

15 hp is a lot, that differs you from 285 hp and 300 hp 😅

Thank God someone conducted this test properly, great job guys

15 hp? just turn up the boost.

Good luck with your annual emissions test taking out your cat ............................
You can tow your car straight to the breakers yard as you won't be able to drive it, legally that is.

Steering wheel is on the wrong side.

Increasing flow doesnt do anything to a modern car without tuning all the computerized crap

Well mine was just stolen so I have no choice

Not a fair test to be honest. Stock cat vs high flow vs no cat would be fair.

I wonder if a naturally aspirated engine like my puny little Honda D16 would be affected much more
Probably an obvious question

Love the accent

A third test comparison with a original equipment cat would have been good.

Im guessing 8 hp

high flow cat come on use a real cat for the test show how restrictive they are.

waste of time. usless video full of marketing

My cat. conv. was just stolen and I'm wondering if it worth it to replace it with a pipe. I just want to reduce the noise rather than getting more HP. It seems the engine is still very loud with the pipe installed. Does the pipe reduce the engine noise at all than without the pipe nor the cat. Conv. installed ?? Also can you drive temporary without the cat., It seems the engine is roaring hard when I step on the gas, even lightly. Thank You for any feedback.

So, less than 2% difference? Thanks for the video!

About to add a 3.5” 200 cell to my car and see what happens… very interested to see the results at semi comparable numbers ~700 wheel.
