I feel it’s important to point out that while a catalytic converter does reduce CO emissions, the main purpose of the design is actually to reduce smog emissions. Smog is a catch-all term for oxides of nitrogen (NOₓ) which are a medley of molecules formed during combustion which consist of a nitrogen atom bonded with various numbers of oxygen atoms, hence the ‘x’ in the name. The key to the cat’s function lies in bond energies of molecules, and the triple covalent bond in NOₓ molecules have much a much higher bond energy than the double bonds in CO, CO₂ O₂, N₂, and other common exhaust products. To remove the NOₓ molecules, the cat media reacts with the exhaust gas by becoming extremely hot, reaching temperatures comparable to the combustion chamber where the NOₓ was formed. Since it takes the same amount of energy to break the bonds as it does to form them, the NOₓ molecules disassociate into monoatomic nitrogen and oxygen as they pass through, and when they exit the cat the temperature drops below what would be required for NOₓ molecules to re-form. The result is a significant decrease in smog emissions and the presence of smog is the smell the emits from a cat-less setup.
70 percent of all emissions are made by less than 100 corporate companies and how many catalytic converters have you seen on jetliners or any airplane and they still use leaded fuel as well 😮
Its also important to note what hardware comes in the box with certain downpipes. Sometimes a cheaper downpipe will be missing a gasket or resuse bolts that were already on the car instead of new hardware.
I've ran an Invidia catless j-pipe and a resonator delete on my 17' WRX for over year now because I really wanted that "diesel" spool sound. I've never had any boost creep oddly enough and have always been aware of the cons of running the set up. Then again this car has been through absolute hell and it's a miracle it's even running still lmao
I smell my cats all the time. They're house cats, eating the same food, pooping in the same litter, and they smell completely different. It intrigues me. Nonsense aside, I learn something new in every one of your videos. You're becoming my favorite channel. I mean, I paused binging Breaking Bad to watch this. You're doing something right!
Lol I can only smell my dog... not even the same 😫 breaking bad! Did the release new seasons?! Appreciate the support and glad the videos are enjoyable 😁
@@Smeedia Well, they came out with that movie not too long ago. But no, I'm just that ine guy on the planet who just started watching it for the first time.
Perfect video. Thanks! Just boosted my miata and noticed I was running lean at higher RPM's. I also noticed the boost was increasing from where I had it set. I installed a test pipe while installing the turbo system... but I'm thinking the cat is going back on. Thanks for explaining everything!
Good info! I may add - If you want to run an OEM VFxx turbo on a catless downpipe, I recommend porting the internal wastegate (which is what I did on my car) It’s a simple process. Remove your turbo, take off the wastegate actuator, and remove the V-band clamp that attaches the exhaust housing. Use a mallet and remove the exhaust housing, being careful not to damage the turbine wheel. Take a Dremel and a grinding bit, and round off the corner that leads exhaust gas to the wastegate. DO NOT ENLARGE THE WASTEGATE HOLE, you’re simply smoothening the hard edge that leads to the wastegate. This encourages exhaust flow out the wastegate instead of going through the turbine. There are a few videos and forum posts on this process, so do your research. I’m on a VF48 e85 at 20 psi, never had an issue with creep. A 3-port EBCS might help, but there’s nothing that can truly eliminate creep other than having a larger wastegate Last and most important, GET A REAL TUNE 🤣
I just got the Invidia catless downpipe and it's amazing. More flames, pops and noise. I had a Grimmspeed look-alike and I ran into a fitment issue because the internal wastegate was hitting a flange on the downpipe. EWG coming in the future...
I've had my WRX for a while now so I know most of the information. But it's always good for a refresher and new owners. Good job we appreciate the effort
Appreciate the support and feedback! Teying to bring all questions into the channel. Once all of the basics are covered lol be making more technical and in depth videos on deeper topics.
EWG is next on my order list for parts. Going to stay catted for the time being but definitely need to make the swap. Hope all is safe where you are and your able to buy toilet paper!
Sheeit dude i didnt know youre studying microbiology! My grandfather is a hugeee microbiologist here in the east coast. He a big part of laboratory alliance hes written books and all. Love your videos man
Bro I love this channel so much. The way everything is explained is super clear and informative. I seriously hope your success comes because it is beyond deserved.
Smeedia however your plan on doing it really works bro. I just got my 2013 WRX and you have helped me so much.

Thanks for even showing love back man, little things like that go a long way for loyal subscribers. Loyal as in super supportive not in a creepy stalker way.
BOOST CREEP FIX!!! I used to own a 2003 WRX and then a 2004 STi. There is a fix we used to do on those for boost creep on a STOCK TURBO. We would enlarge toe orifice on the wastegate. I did several of them for other people too. When you have the downpipe off of the turbo you remove the clip and rod from the wastegate valve. Open the valve and grind a VERY SMALL amount off the wastegate hole and keep it round. You can always take off more, you can never put it back. if you take too much material off you won't get enough boost. Solved the creep issue on my STi with a catless downpipe and many others too.
I’m very glad I subbed to you, you definitely know what you’re talking about through all of your videos. I was told by my local tuning shop to get a catted J-pipe, is that a down pipe still? Is it basically just another way of saying downpipe?
Loving the videos man! I have owned a 2015 sti for 3 months now, went from a 99 GC8 NA to this and am so happy with it, your videos are very helpful for me and your great at explaining I can tell you know best!. Respect from Perth Western Australia 🇦🇺
Bro, 100% video 👌👌. I bought a bottom range 09 wrx hatch. Nothing done to it. All I've done is 3" turbo back decat. STI style rear muffler been cut open and all the crap removed. Welder back up. Took housing off oem air filter front part to reviel filter. Half inch spacer last joint before rear muffler. Got the rumble, got the turbo spool sound, got natural pop and bang through gear change. No boost problem, and it's like a totally different car. It almost pulls my hands off the steering wheel through gear change. I'm in the UK running standard UK 99ron petrol???
@@Smeedia we get like 3 kind of grade 99ron if you listen to the public. Most 99 is available at our supermarket pump station's, but regard as not the best. There are only a handful of genuine garages who sell 100% quality 99.But that's just where I live, Wales United Kingdom. I believe that in the actual uk the quality is much better. What's your bhp, sorry I only just started watching your chanel today 📺💯📺
Great video. Can't wait for the ewg video need one for my car as I have a grimmspeed limited catted downpipe but still having boost creep issues on my car
I know the car has changed since this video. But that thumbnail looks soooooo goooood! I wonder if a gt wing would suit my wrx. I track my car and would love to add some downforce.
Great video and great explanation and comparison. I was very on the fence of what to go with and i have heard catted is the way to go but i wanted them “racecar vibes” but now i think i will go catted thanks alot!
Keep up the good work, Love the videos. Wanted to see if you are considering installing aftermarket seats for the WRX/STI or the BRZ and of course making a video?
Car mods is about finding balance. With car mods $ tip the scale heavily. Even with catted you can generate massive hp and torque and a sweet even loud exhaust note, if high decibels are your thing. Lastly you are emissions legal regardless of where you drive or end up driving should you move. One less thing to worry about.
I wish someone would do this test on a non boosted engine cause I think it would gain considerably but everyone seems to be testing boosted and the less heat from test pipe should be of some benefit also
I have an Invidia Q300 and the stock downpipe on my 2009 Impreza WRX currently. I’m a little nervous about emissions (I want to go Catted) and also sound laws in Massachusetts are WAY more strict
Always killing it with the great content. Stay safe out there in Wa...craziness. Ouuuu T-shirt on its way. Will be rocking it out here at the east coast Subi meets when they finally happen
Hey man, I love your stuff and the information you provide. I am looking at getting into a 2015+ wrx. I plan to go stage 2. I am curious what your thoughts of buying a rebuilt title wrx. I plan to do mechanic check and everything that goes with that. Wanted to know your opinion on it though. Thanks!
Tough choice, I live in Ohio, I don't think they mess with the emissions check. If i Go catless to match my Invidia R400, still need to get protune in order to run the intake as well. But with the situation of "THAT" the tuner is not working at the time. Good thing you clarified running catless won't work with OTS Maps.
Did you get dumped on today too? Woke up to a winter wonderland and no traffic on the streets in the couv today. PDX is starting to wake up, but damn i can't wait to get done with work and head back home to have some fun in the snow!
Yo Yo! Great vid as always! Recently pro-tuned my 06 WRX to stage2+ w/DC intake and STI intercooler BUT without adding a new catback exhaust for emission/noise reasons (I live in VA). Will putting an HKS Hi-power on a stock 06 downpipe work fine or should I do the catted downpipe as well? I'm hoping it'll fix the DAM problems I've had since we got it tuned. It wants to run faster but restricted by the exhaust airflow. Thanks in advance!
Regarding ceramic coating the down/j pipes: I'm assuming there's some specialized coatings for that specific purpose? Or does the plain old ceramic/graphene coating usually for the paint work the same? ✌
@@Smeedia ✌️ parts going on this weekend so I'll have to look into alternatives to address the heat post install. Maybe some heat resistant sleeves on hoses near the jpipe.
Getting a downpipe doesn't automatically void your warranty. Look up the Magnuson Moss warranty act. The dealership has to prove that your installed after market part is what caused said malfunction
That's not true, the Magnuson moss warranty act covers third party manufacturers that make OE emplacement parts. 🙏 th-cam.com/video/n1Xh5kGV_l8/w-d-xo.html
@@Smeedia i’m going catless with the Cobb OTS tune paired with the Q300 for my 2006 spec.B. I baby my car though, rarely go into boost as it’s just my daily driver.
Great video buddy. My STI has sports cat and was tuned at 1.25 bar three week later it’s at 1.33bar and has stayed there since. 12 months later it’s still at 1.33bar. I’m guessing it’s boost creep, but why hasn’t it gone higher? Should I be worried? Cheers
I woukdent be worries unless your seeing massive spikes. That's only a small increase (around 1 PSI) haven't used Bar as a measurement in a little while! Lol but if you see around 1.40 bar then I would back off on the throttle a little bit. The small jump could be temperature diffrence changing the density of the ambient air.
smeedia huge fan!! currently collecting mods for my build watching your vids, have a blouch 2.5xtr 10cm with invidia catless down pipe would porting the iwg housing be sufficient enough to eliminate boost creep? or should i juat run a ewg? what causes boost creep when running a cattless downpipe?
Why I ended up going with a catted over cattless for my wrx is because if you plan on running e85 in the future with a catted you can but if you have a cattless you are not able to
I want to buy a cobb catted non resonated 3” j pipe/downpipe. Does replacing stock downpipe cause any reliability issues and or engine damage? A dealer said yes but everyone on the internet says no?
I have a catted jpipe currently but I’m looking at going catless in the future just to have fun with pops and flames every once in a while but I’m not looking forward to having to install again
Nice work brother , I have a Sym's catted downpipe , I have run without it (cattless) and don't see much difference . I'm all in cause $3k I have to like it !
I might go catted downpipe only for the emissions reason. And also i don't care about sound so i want to sound as stock as i can. The only reason for me even thinking of a downpipe is because i am going to custom tune my car past my current tune and I've been told that i will need it since i will be running a lot of psi
Got me the invidia R400 and a catted j pipe and i like how it sounds. Not gonna lie but that Tomei titanium extreme cat back has caught my eyes and ears.
When you buy a catless downpipe for your WRX when you had no idea what boost creep was and now want to question your existence and also question if you can throw 30 lbs of boost at your ej20
Hey man I have a V7 JDM WRX so I am needing to put a JDM downpipe on them. I found a company who does both a catless vs catted and I originally wanted the catted because I was worried about the smell and boost creep butr decided to go with catless due to cost. However, watching this has made me again re evaluate my choices. Is it cheaper to just buy a High Flow cat and be done with it, or cheaper to grab a Catless downpipe and do an internal to external wastegate conversion? I am planning on replacing my TD04 with a VF30 at the same time as I do the Downpipe.
If your going to buy a cat and weld it knto the downpipe it would be cheaper than an WWG or buying a catted downpipe. But the EWG will just mitigate and remove an u potential issues that you might be having later down the road. My suggestion would be to use your cables downpipe and go EWG, a 38mm EWG would be good for your application
@@Smeedia The Catless pipe I am looking at is $350 and the High FLow is $650 (US dollars for both). I am only doing the Downpipe, the VF30 conversion and getting that all installed at once, getting 1 tune and then leaving the car there. I wont be adding any more performance modifcations. With that in mind, I am obviously now worried about boost creep. In terms of cost, would getting the cattless and EWG and accompaning up pipe etc be cheaper, or will the High FLow Cat be cheaper. Also, if I am running a VF30 on a WRX, making around say 300hp at 15psi of boost, would boost creep still be an issue, or is it only if you push higher levels of boost? Cheers
Can you do a things to know before you straight pipe I want to straight pipe my wrx but all these exhaust terms and stuff got me so confused so fat I only have a remark muffler delete
Dude! One more badass video, I have a muffler delete, accesport and Cobb fs and trying to add Cobb j pipe catted, what ots do you recommend and about how much hp would I gain?

I wish I would have watched this video sooner. I didn't properly wrap my downpipe like he said.. and now I have a lot of extra bills called children.
Car mods is about finding balance. With car mods $ tip the scale heavily. Even with catted you can generate massive hp and torque and a sweet even loud exhaust note, if high decibels are your thing. Lastly you are emissions legal regardless of where you drive or end up driving should you move. One less thing to worry about.
Good to know, wasent sure about federal emission standards on that one.
I wish someone would do this test on a non boosted engine cause I think it would gain considerably but everyone seems to be testing boosted and the less heat from test pipe should be of some benefit also
3 years ago… stay safe from covid my friend… 3 years already is crazy
Love this video, I’m new to the subi community and I’ve learned so much, thank you!
Congrats on the car and glad the videos are helping 😁😁😁
I was looking at the turboxs catted j pipe since it’s on sale for a good price.
Hey man love the video. Also what kind of wheels are you rocking. Very dope. Thanks for your time.
Thank you! Ans they are work emotion D9R 😁
We need more pics of this wrb sti, looks awesome
Thank you 🙌😁
It’s nice to find a channel based in Washington
There's a couple of us on here 🙌😁
i subscribed right when you gave the be safe warning hahaha love the energy
Appreciate the support and gotta always add it 😁
@@Smeedia :D
😁😁😁😁
I have an Invidia Q300 and the stock downpipe on my 2009 Impreza WRX currently.
I’m a little nervous about emissions (I want to go Catted) and also sound laws in Massachusetts are WAY more strict
Catted with a resonator and a muffler and you should be okay on the sound aspect 🤙
How is the microbiology career like ? It sounds super interesting. Subie lookin real nice btw
The microbiology aspect is only about 30% of what I do but its definitely interesting a lot to learn! And thank you!
Always killing it with the great content. Stay safe out there in Wa...craziness. Ouuuu T-shirt on its way. Will be rocking it out here at the east coast Subi meets when they finally happen
Appreciate the support my man! Its getting crazy out here but if they shut down everyone gets more videos 😅
Hey man, I love your stuff and the information you provide. I am looking at getting into a 2015+ wrx. I plan to go stage 2. I am curious what your thoughts of buying a rebuilt title wrx. I plan to do mechanic check and everything that goes with that. Wanted to know your opinion on it though. Thanks!
Depends on what it was rebuilt for but for the right price if your planning to modify it, its not a bad idea 😉
Smeedia that is what I was thinking. I want to lightly modify it. Make it a fun daily and that’s about it.
Tough choice, I live in Ohio, I don't think they mess with the emissions check. If i Go catless to match my Invidia R400, still need to get protune in order to run the intake as well. But with the situation of "THAT" the tuner is not working at the time. Good thing you clarified running catless won't work with OTS Maps.
I made the mistake 😅 dont make my mistakes lol
@@Smeedia lol, i think ill save a little more and get the grimmspeed limited, and add an electric cutout for the fun💪
I would love to put one in my 21 Type s preferably catted
I went with a catted downpipe because I'm not a 20 year old Honda kid and I like my car to be comfortable.
I have always liked your videos good content!
Eyyyy, appreciate the support 🙏 🔥
Did you get dumped on today too? Woke up to a winter wonderland and no traffic on the streets in the couv today. PDX is starting to wake up, but damn i can't wait to get done with work and head back home to have some fun in the snow!
No snow here thank god 😅 I'm so over the snow. Like 10 miles away the got dumped on though. Everyone here straight up panics with the snow
Love the videos man. Where can I get a protune or etune here in WA?
I'd suggest PRE, English or Surgeline 🔥🙌
Yo Yo! Great vid as always! Recently pro-tuned my 06 WRX to stage2+ w/DC intake and STI intercooler BUT without adding a new catback exhaust for emission/noise reasons (I live in VA). Will putting an HKS Hi-power on a stock 06 downpipe work fine or should I do the catted downpipe as well? I'm hoping it'll fix the DAM problems I've had since we got it tuned. It wants to run faster but restricted by the exhaust airflow. Thanks in advance!
It'll be fine to toss on, if you install and downpipe you will need to get another tune 🙏
🤘Yes dood thx a bunch, keep up the awesome work!
Regarding ceramic coating the down/j pipes: I'm assuming there's some specialized coatings for that specific purpose? Or does the plain old ceramic/graphene coating usually for the paint work the same? ✌
They typically use a special costing that's very resistant to heat 🔥
@@Smeedia ✌️ parts going on this weekend so I'll have to look into alternatives to address the heat post install. Maybe some heat resistant sleeves on hoses near the jpipe.
Getting a downpipe doesn't automatically void your warranty. Look up the Magnuson Moss warranty act. The dealership has to prove that your installed after market part is what caused said malfunction
That's not true, the Magnuson moss warranty act covers third party manufacturers that make OE emplacement parts. 🙏

Love this guys’ videos keep it up man !!!
Thank you! A lot more on the way!
Love my invidia catless jpipe and q300 exhaust. Downside is gassing yourself out at red lights or telling a passenger what that smell is
Haha it happens 😂😂😂
A great video, thanks. I am installing a catless downpipe there. Should I drive below 5,000 rpm at all times before I get a pro tune?
I would suggest that, you can still get on it a little just really keep an eye on your PSI to make sure your not overboosting 🙏
@@Smeedia i’m going catless with the Cobb OTS tune paired with the Q300 for my 2006 spec.B. I baby my car though, rarely go into boost as it’s just my daily driver.
@@SpyceptModz which ots tune did you do??
Great video buddy. My STI has sports cat and was tuned at 1.25 bar three week later it’s at 1.33bar and has stayed there since. 12 months later it’s still at 1.33bar. I’m guessing it’s boost creep, but why hasn’t it gone higher? Should I be worried? Cheers
I woukdent be worries unless your seeing massive spikes. That's only a small increase (around 1 PSI) haven't used Bar as a measurement in a little while! Lol but if you see around 1.40 bar then I would back off on the throttle a little bit. The small jump could be temperature diffrence changing the density of the ambient air.
Smeedia thanks buddy that’s what my tuner said 👍
smeedia huge fan!! currently collecting mods for my build watching your vids, have a blouch 2.5xtr 10cm with invidia catless down pipe would porting the iwg housing be sufficient enough to eliminate boost creep? or should i juat run a ewg? what causes boost creep when running a cattless downpipe?
Why I ended up going with a catted over cattless for my wrx is because if you plan on running e85 in the future with a catted you can but if you have a cattless you are not able to
Because of your state laws?
thoroughly well explained thanks!
Just bought a "Turbo XS" chatted pipe for $550. Going to Cerakote the whole exhaust
Really like your channel man, really chill vibes. Ill be sure not to grab anyones butts lol.
Haha no butt hole grabbing 😅
I want to buy a cobb catted non resonated 3” j pipe/downpipe. Does replacing stock downpipe cause any reliability issues and or engine damage? A dealer said yes but everyone on the internet says no?
As long as the car is tuned for it, no it will not
Might be stupid question. But if I go catless... And get headers with external waisgates, will that work as the waistgates for boost creep?
My new subie guru! 🙌 Love the info.
🙏🔥😁
I have a catted jpipe currently but I’m looking at going catless in the future just to have fun with pops and flames every once in a while but I’m not looking forward to having to install again
The studs on the FA20s turbo are always the worst. Seen them strip so many times 😖
Nice work brother , I have a Sym's catted downpipe , I have run without it (cattless) and don't see much difference . I'm all in cause $3k I have to like it !
Lol I dont blame you! I'll be there soon 🔥
I might go catted downpipe only for the emissions reason. And also i don't care about sound so i want to sound as stock as i can. The only reason for me even thinking of a downpipe is because i am going to custom tune my car past my current tune and I've been told that i will need it since i will be running a lot of psi
The downpipe will definitely help with the tune 🙏
Got me the invidia R400 and a catted j pipe and i like how it sounds. Not gonna lie but that Tomei titanium extreme cat back has caught my eyes and ears.
That thing is loud as hell, 😅 but I cant judge that my ETS is SO LOUD also lol
@@Smeedia which is louder the tomei or the R400?
@@jameskocks4734 tomei 😅😅😅
@@Smeedia cool thanks.
What j pipe you running?
Another great video! Keep it up!
Thank you! 😁
When you buy a catless downpipe for your WRX when you had no idea what boost creep was and now want to question your existence and also question if you can throw 30 lbs of boost at your ej20
Send it with full boost!!! Jk, just keep an eye on your PSI, in the wknter is when you'll really see it start to creep
Great video again appreciate the info🤙
Appreciate the support and anytime!
Hey man
I have a V7 JDM WRX so I am needing to put a JDM downpipe on them. I found a company who does both a catless vs catted and I originally wanted the catted because I was worried about the smell and boost creep butr decided to go with catless due to cost. However, watching this has made me again re evaluate my choices. Is it cheaper to just buy a High Flow cat and be done with it, or cheaper to grab a Catless downpipe and do an internal to external wastegate conversion? I am planning on replacing my TD04 with a VF30 at the same time as I do the Downpipe.
If your going to buy a cat and weld it knto the downpipe it would be cheaper than an WWG or buying a catted downpipe. But the EWG will just mitigate and remove an u potential issues that you might be having later down the road. My suggestion would be to use your cables downpipe and go EWG, a 38mm EWG would be good for your application
@@Smeedia The Catless pipe I am looking at is $350 and the High FLow is $650 (US dollars for both). I am only doing the Downpipe, the VF30 conversion and getting that all installed at once, getting 1 tune and then leaving the car there. I wont be adding any more performance modifcations. With that in mind, I am obviously now worried about boost creep. In terms of cost, would getting the cattless and EWG and accompaning up pipe etc be cheaper, or will the High FLow Cat be cheaper.
Also, if I am running a VF30 on a WRX, making around say 300hp at 15psi of boost, would boost creep still be an issue, or is it only if you push higher levels of boost?
Cheers
Can you do a things to know before you straight pipe I want to straight pipe my wrx but all these exhaust terms and stuff got me so confused so fat I only have a remark muffler delete
Dude!
One more badass video, I have a muffler delete, accesport and Cobb fs and trying to add Cobb j pipe catted, what ots do you recommend and about how much hp would I gain?
I wluld use the stage 2 OTS Map and you should expect an estimated 260ish WHP 😁😁
If money was not an issue which one of the 3 you recommend would you buy, I want catted,
After this my next upgrade e85
Cobb would be my go to choice
Smeedia I’m about to buy the Cobb, should I go without a resonator for more power or does it make a difference ?
