High-Flow Catalytic Converter Install - Project ASS2000 - EP14

[@madsmax9273]

lets see this ass2000 in action on track soon!

[@speedacademy]

Mads Max After the Dyno and aero mods it's off to the track. Will probably be closer to the end of this month since we have so many other things to finish off.

[@mattuk180586]

I like the little clip at the end. Sounds exactly like me when I work on my car. lol I'm cursing like a sailer the whole time.

[@speedacademy]

mattuk180586 I'm actually really bad with it, makes me sound like a rage-aholic LOL

[@SlowReactionK]

You were missing the correct Teflon insulator for your large gas lens which is why your welds came out that way. The cup was probably pulling oxygen from the back side and not allowing proper argon shielding.

[@imSchwaggy]

When the only thing you can afford from the bill so far is the penny at the end of the total :/ .

[@speedacademy]

Jermaine Simpson This mad us laugh but we feel ya. Money is always tight especially when it comes to modding a car!

[@derekstevens257]

Where do they get the money to do all these builds, or are they a shop?

[@middletonrippberger]

The issue with your welds is that you have the amperage way to high for thin stainless. looked like you had it at 85 amp, normally I run about 45 amps on a job like that. also being stainless it should have been back purged to reduce the risk of the welds cracking later.

[@middletonrippberger]

On a side note you do know that the Vibrant and the oem s2000 cat are both spun metal core cats? and the larger core diameter of the oem cat cores would suggest that it may actually have the higher flow capacity of the two. and you if i'm not mistaken the oem cat has a 60mm (2.36in) inlet and outlet and you dropped that to 2.25in? ........... you should have left the stock cat on.

[@speedacademy]

Given that our car is about 15 years old and meant for both emissions and performance we're willing to bet that the Vibrant cat is better performing. And the stock diameter on the OEM cat is 2.25. Like I said I thought I ordered a 2.5-inch test pipe...

[@markdaman9]

get a cheap pipe expander from princess auto (or harbour freight) to make the job so much easier next time. if you'll be doing it a lot i suggest a snapon versuion though :P

[@speedacademy]

Markdaman9 You know what's funny Mark, after this job I was putting my tools away and noticed that I had a pipe expander in my tool box!! Ah well, next time.

[@cmendoza1094]

What type of expanders do they have in canuckistan? All of the ones I've found are made of cheese. Looking at a Lisle expander now, 100$+

[@vaajchang]

can we get an exhaust sound and fly by vid of the ass2000 with this mod and tanabe

[@speedacademy]

vaajchang The next video will be on the dyno so you can hear the exhaust. Truth be told, I didnt hear any difference after installing the cat. Sounds just like with the stock cat.

[@leedress2187]

Thanks for showing the blooper at the end.

[@s2kinky577]

lol did nobody see his glove smoke? Right after touching the test pipe, when he finished the weld on the bung?m

[@Oldieeeee]

Is it CARB compliant?

[@Garage13RLM]

Gotta love good quality parts! but the welds could definitely use some improvements lol

[@cmendoza1094]

They look like mig welds. That I did...

[@Z33Garage]

I want my channel to grow like this one. I love watching your videos and I get many ideas for future episodes of z33 repairs on my own channel. Keep up the great work!!

[@speedacademy]

Z33 Garage Keep making those videos and it will grow!

[@Z33Garage]

Speed Academy thanks, I will! I'm also trying to be fiscally responsible haha!

[@speedacademy]

Z33 Garage That's always the struggle!

[@Smngorin]

Lol the end clip shows that working with metal is not easy! You where annoyed. I would too! Haha

[@AdonisGaming93]

why not just buy a high-flow cat that is a straigth bolt on? Was there not easy bolt right on high flow cat back in 2015? Berk HFC are really great in 2020 for example.

[@KoiTimeUSA]

great video.. dont they sell gesi HFC for the s2000? more videos now....

[@speedacademy]

Tony Nguyen Not directly through Vibrant. There may be a shop or manufacturer that uses it and builds their own piping?

[@KoiTimeUSA]

r u guys a performance shop base out of cananda?

[@speedacademy]

Tony Nguyen No, we don't sell any products nor do we work on other people's projects.

[@tijeansharpe566]

Have you guys ever thought of a Mitsubishi 3000gt vr4 for a build

[@speedacademy]

tijean sharpe Peter used to own a ton of DSMs so he knows the 3000GT VR4 very well and it's a gorgeous looking car but the complexity of it and weight keep us from the top of our list of project cars to build next.

[@someusername121]

Why that cat instead of a Magnaflow one that only costs $100?

[@highrzr]

Hum...cut twice measure once example?

[@patrickstarr87]

Really enjoy watching this build! Seeing stuff go wrong just like it would doing it ourselves and how you guys go about trouble shooting is awesome 👍👍👍🍻

[@verginsergin]

Love the content, the welds look like chewed bubble gum though.

[@supercooled]

Is a HFC the same as a down pipe?

[@speedacademy]

No, one is for emissions the other is what usually connects the manifold/header to the HFC (catalytic converter)

[@PowellMoore]

I had a strange feeling that pipe was a bit small

[@woofer2121]

how does a smaller cat flow more?

[@speedacademy]

Edward Grindstaff Because there is less material to flow through which makes removes the restriction that the factory cat has but still provides the proper filtration to ensure emissions compliance. That's why its such an expensive piece.

[@stu19991]

What kind of welder is that?

[@speedacademy]

Miller Diversion 180 welder

[@travisproteau8285]

So is it 2.5 to 2.25 then back to 2.5?

[@speedacademy]

Travis Proteau No, it's 2.25 to 2.5 then back to 2.25. The up size in the cat will only benefit flow but if the cat was the one I ordered then it would have been 2.5 which is ideal for this application. Regardless, being NA the difference doesnt matter.

[@SlowDriver2024]

Why not just get a Magnaflow federal legal cat pipe? Flows better than stock because of less cell count, and it mounts right on, no mess no fuss. :)

[@speedacademy]

+2MANYCARS Vibrant is local to us and their GESI cat is one of the best for emissions and flow. Hence why we use it but we've heard good things about Magnaflow.

[@xorkatoss]

Question: My Colt Czt 2006 has 2 catalytic converters, I removed the 2nd but kept the 1st so the "check engine" light doesn't show and I replaced it with a stainless steel pipe...would it be better to use a High-Flow Catalytic Converter like the vid or just keep it like this? which method actually gives higher air flow? thanks!

[@fartknocker7246]

Modern catalytic converters aren't really restrictive at all. The reason you want to replace them is because stock converters have a ceramic core. They will inevitably melt as exhaust gas temperatures rise. If you're worried about emissions, and live in CA, you're sort of SOL as there aren't any CARB certified metal core cats, but the GESI/Vibrant Performance cat in this video is Canada and US EPA certified. It should pass emissions mostly everywhere other than California. It even keeps the CEL off in my 2016 WRX. It's a real cat that actually reduces emissions unlike other "high flow" cats that come in downpipes from most manufacturers.

[@DeKay]

Man. Berk makes a high flow cat that's about half that cost and would have been just a simple bolt on!

[@speedacademy]

De Kay The Berk hi-flo cat is a magna flow not a Vibrant one. We specifically run the GESI one for emissions purposes.

[@Bunchofhelmets]

Having a off day, or the curse of the ass2k.

[@Coda5610]

Im so glad we dont have Smog or emissions here in Kansas, USA.

[@AguilaJR]

Keep it that way, install highflowcats 🖒 and dont lose that priviledge

[@justintime6160]

Nice video guys... Ahhh always the cat.. Tried to fit my high flow the other day and of course the flanges don't match up and everyone knows what that means... Off to spend more $$$ cutting and re fitting.. Zzzzz

[@speedacademy]

***** You know the struggle! That's how it always goes.

[@jehartono]

HAHA "Why is this all of a sudden so crooked! Jesus Christ... What the hell... God damn man!" haha so funny.. Thumbs up for not swearing in all of your videos. Really enjoy watching this series. Keep it up!

[@speedacademy]

+Jeremy Hartono You should hear all the slander that didnt make the cut haha.

[@cepsixty9]

Go Go Go!!! ass2000

[@F_r_a_n_y]

I hope it makes 250 or more after all that work.

[@speedacademy]

Frany To the flywheel haha. There's no chance it'll make that much power with just bolt-ons. Especially since we have no tuning.

[@SupaNinjaTurtle1]

+Speed Academy speaking tuning, are you guys planning on sticking the hi flow cat or would consider a test pipe in its place? I know hfc are more emission compliant. From what I know test pipes release a few more horses especially around tuning. Either way, I love the build!!! I've watched every episode 5 times over!!! Lol good job guys!

[@speedacademy]

SupaNinjaTurtle1 There's no reason for us to put on a test pipe. The GESI hi flow cat is incredibly efficient and flows so well that we can't imagine a test pipe will pick up power. We may actually test it in the future. Also, the cops here in Ontario will tow the car if its missing a cat so we don't want to take any chances. Oh and amazing to hear that you've watched them so many times :D

[@SupaNinjaTurtle1]

+Speed Academy that would be a nice comparison between the hi flow cat and test pipe on the dyno between tune sessions.Ontario police exactly like Californian police lol yeah better safe than sorry haha Yeah I am a fan of s2000s, I own an S2000, and maybe down the line I'll a much bigger budget. I'm also looking forward to see how you guys do against the jaguar F type with these mods. I think the downforce will be significant.

[@tommythomas711]

yea you crazy if im payn that

[@Trinibad718]

why the fuck will you put a test pipe with cats lmfaoo someone come get this KZbinr

[@spaggs111]

Oh man, as soon as you rigged it with the 2.25 test pipe you lost.

[@st3v3nb915]

Dam all that money ,

[@boosted_2j]

thats mad money son

[@speedacademy]

Echo-GAMING Gotta pay to play! Especially if you want good flow while passing emissions.

[@boosted_2j]

true

[@brianneal9204]

only 300-500hp? well, for imports I guess it's ok.

[@carguy1320]

Watching all these vids, I still don't get why you do 99% of the work and keep the other guy around?

[@speedacademy]

+Bryan Ballare Because I love Dave so much that I'd never get rid of him lol

[@mikeyg8133]

Hot as balls? 30°?!

[@ScottPC]

30c I imagine

[@Dddddddd348]

berk hi flow cat is much easier ;)

[@speedacademy]

+David Sallis Yes but this is so much funner!

[@ViperKillerWannabe]

Ass2000 indeed... :D

[@BenExell]

naaa just dcat ;)

[@deshiitimmons416]

U mean cheese and rice not Jesus Christ Lol.😄

[@speedacademy]

Deshii Timmons I tend to use the Lords name in vain a little too much :O
