So you did a d-cat but didn't like the sound so added another resonator, still not happy you cut off the old resonator and call it a resonator delete!!? What am I missing here didn't you just swap out an old resonator for a new one ?

😮 comments

Decat downpipe and tune gave 120+hp on bmw 440i also sounds much much more real.

thank you

Question… where is the cat located on a fiesta st180 (sorry for the stupid question) and if I wanted to decat the fiesta do i really have to buy a new down pipe?

no one mentions faster burning of the rear and middle exhaust, due to excessive exhaust temperatures !!

Do you have any report of cat delete on Ford focus 2014?

I’ve been dealing with so many exhaust issues with my subaru lately. I find it so stupid they would create a vehicle to burn up so much oil because they can’t make the piston rings the right size, then maybe put it on a one owner under 100,000 mile warranty if u bother the shit out of the dealership to fix it, not necessarily garnered to fit it either. But if you keep adding in oil, it only later ruins the catalytic converters and eventually the engine itself

I have a Isuzu kb250 dteq with 160k kms on it. Is it good for a turbo diesel and the longevity of the vehicle?

Do you need a tune after? Is it bad for the engine if you don't tune it?

Will fuel economy increase from a decat ? Also mine is a diesel turbo charged vehicle.. will it effect my turbo

i only heard Performance gain and Loud Sound

Welll Our provincial Government Rescinded Emissions testings.. Entirely . As it proved Pointless. Beyond that when Bupinders' Gravel truck Stops putting out Twin Columns of Solid Soot at each gear change.... I will start feeling guilty . Cat gutting changed the sound a Little bit.. but not v much at all, as Turbos do A Very good job of chopping up ex sounds . Many ECU programs can be modded to delete the 2 nd (downstream) O2 sensor. Front one doesn't care as it measure Before the catalytic.

What's the best place to do software and brakes upgrade on my runx rsi. I'm based in ladybrand- free state

even tho i know this video is old i wanted to say that iv put one on my 2007 Pacifica with the 4.0 v6 and yes it did increase throttle response and power and fuel economy and im planning on transforming it into my towing rig and for that id say it was worth it for my case all the parts for me was only 63.27 all together it was cheap and easy to do disclaimer: all i did was put the filter over my old filter airduct and it seems to throw air harsh so it worked for me

Dude that’s exactly what my old SR yaris used to sound like with just a backbox delete, really wish I’d done more to that thing but I sold it 😢

My exhaust smells like sweet sweet corn! 😉 😉

My catless Ford V10 with a glass pack sounds absurd. I need to tone it down a bit. My cat got stolen got to get a new one ha. Colorado laws suck though and the exhaust shops have to charge for California compliant overpriced trash, so because the law is unachievable for me, it goes catless. Sorry everyone I'd love to spend $35 to fix this myself but I cant get a regular car shipped here.

Rev range???

My other shit box os a Bentley.....YAR

He drives it so wrong 🥲

Nice 👌 mine 406 crazy car

Come steal mine off my ram

Just curious if you have ever done a before and after dyna test to see if you actually got more power with the CAT delete. I have done this with a couple cars and there was a little power gain at red line on one and the other actually lost power. In both cases, low and midrange power was slightly lower. It is many times a thing of 'It has to be faster because I spent all this time and money on the mod." A seat of the pants thing not based on actual tests like on a dynamometer. Now, if the converter is plugged, of course things will get better. But, if the converter is in good shape, the improvement may not be there with a cat delete. A lot also depends on the engine management system and how it reads the O2 and air flow sensors.

Different animal once ya let her breath!!

Lekker boet! Would love to take my little Mazda for a few laps! I wonder if it's quicker than yours? 🤣🤣🤣🤣

That’s F1 innit!

Lekker Paul!

Mine had an injector fail which put raw fuel through the cat, so it’s toast

This is the Best Video Ever 👍

So why are people stealing the CAT if it is not that important

Have you ever tried a Dynatech Torque muffler ? This is installed as close as possible right after your short headers, it provides more torque.

Good day - I have a 1.2 TSI really like the idea of cat delete and tune stage 1 (But some people say not to do the cat delete) Not good for the car. Just want to know your personal opinion on it for a daily car / Road trip car. Should I do downpipe + TUNE or Just TUNE.

Does a cat delete increase RPM?

Decat doesn’t improve power until your engine is well over 600hp on a single exhaust cat. Even less difference running dual exhaust. The reason is hot gases flow a lot better than cooler denser gases. The cats are red hot inside and increase exhaust flow. So as long as your cat isn't melted from raw fuel hitting it, than there is no reason not to run a cat. This has been dyno proven lots of times. In fact sometimes a car will lose a few hp without the cat, because the exhaust gases are cooling too soon.

To me, no amount of raspy, buzzy, tinny-ness sounds good.

He looks and sound like Drew McIntyre wwe

I'm a newbie, so I did the cat delete and put a free flow muffler. I love the sound and a little performance gain, but it's too loud, is there anyway to reduce the sound a little bit? Maybe replace the muffler? I heard one of those hks legal mufflers make the sound bassier and reduce the loudness quite a bit.

Great video! I have a question tho, i recently upgraded my intake and did a tuning (engine remapping). is it better to do a cat delete?

Most people doing a cat delete don't give a flying F what other people think 😉

I love the smell of a car without a car my ba falcon is decated and I find myself standing behind it a fare bit

I had to get a new downpipe on my car and it was about $650 because they HAD to put 2 cats on one pipe. About 2 years later I get the infamous P0420 code. I try a spacer on the O2 sensor and it works instantly! So FK buying more cats, i just hollowed out these new ones and the spacer still works AND it passed inspection. Yes, she runs better, accelerates quicker, is slightly louder, but she's got 220k miles and she's so happy to have that restriction removed

No cat. But i do have a resonators. But if car sits for a few month it will smoke for about a day. I store the car during the winter so everyspring i have to do minor maintenance. Its a 92 3000gt and no cat for 28 years. But i only put 22k miles on it in the past 18 years. But it runs great😂

The main pro is better fuel mileage! Why do you refuse to say this? I did have a 1979 cheverlet suburban. I ran headers and dual exhaust and was getting 18mpg highway. I moved to California and was forced to smog it. Mileage dropped to 8mpg. Please explain this.....

Excellent video

dont care. removed cat my car sounds like a dog now

decat for flames >>>

Or someone stole your CC and you can't afford a new one.

Enjoyed the vid brother!. I was wondering if you remove the cats off a vehicle. Do you have to get a tune or can you just drive the car like you never removed cats?

My cat was stolen from under my vehicle, and replaced by a dead crackhead!
