- I should have seen this coming. If you are thinking about de-catting your Celica, take a look at this video and a hard look in the mirror. Learn from my mistakes and do better.
Definitely going to change this set up ASAP. My DNA exhaust was rattling and falling apart so I'm going for a custom set up. This is the first phase of putting the system together and we have a long way to go.
He said I'm a man with a wife and a child but got his back seats gutted out lol 😂😂😂
Lmao, I know dude. Finally had to get a 2nd car. Not putting that interior back in, too many broken clips now 😂
Jayon_Starr u are aware that people own more than one car right?? 😆
I have a baby seat in the back of mine. My little girl loves to take off fast and whip around the corners and says weeee when I do! 😂
I've actually got a deep sound out of mine. DC Sports Headers, cat delete, res delete, and a Magnaflow axle back exhaust muffler with exhaust tip. And i got to say it sounds very nice. You don't get a ricer sound at all! And one day my dad wanted to run an errand and i let him drive my car and it sounded even better not being the one driving it! When he pulled out on the highway it sounded really nice. Mine is a 2000 Celica GT-S.
That's awesome! It is hard to get a small 4 cylinder to sound good. I've changed it up a bit, added a small resonator and a black widow muffler. It's raspy but sounds pretty good.
im a grown men with a wive and 3 sons and im driving a subaru gtt 98 with 300 horsepower
and a mr2 with 280 horsepower both with open pipe,s
my wive and children love it hahahahaha
Don’t act like you don’t like it, man 😂
Some part of me probably did 😅
Update: ordered a black widow race venom muffler. Never heard one on a smaller engine, so we'll see how that goes 😂
U got any updates?
I did that to my car and got a ticket on the way home. It was obnoxious so glad I got a legit exhaust
😂😂😂 i went through this same problem when i first bought my celica, it was straight piped too! i was dying watching the video
On an aspirated engine removing the cat and release all the exhaust cuts pressure at low rpm and the car goes much slower in recovery. I had 200 cells and cat back exhaust from invidia and we had 200 hp on dyno! GREAT CAR
Completely agree. I've been driving exclusively 1st gen vibe gt's (same engine and trans, basically an American matrix xrs) my 05 gt had a clogged cat but it would still push around 180hp and do 5second 0-60 times. As soon as the cat split open, was racing a random old body mustang who tried pulling away from me after slowing me down by pulling out in front of me, cat blew open at around 120 redlining 4th. When that happened I noticed about a .5 to 1 second loss in my 0-60 time, but gained around 4 seconds to my 0-100 by keeping it above 5k rpm. Without a cat it definitely takes off slower and bogs out alot more in 1st, but as long as your T.W.O and redlining, after 1st gears 5k rpm point it starts picking up all the power it lost.
My idea was to do a cat delete N/A by replacing the cat and some piping more down stream with a glass pack then a small steel cone in front of it to restrict some exhaust and hopefully keep the back pressure up, then testing and keep shaving off more and more of the top of the cone till it gets to a point the engine doesnt have the restriction of the cats honeycombs, but it doesnt loose any power under 5k rpm.
Seems cheaper to me than a 1k$+ turbo or supercharger kit that the engine probably cant handle being at 280k miles and nearly 20 years old.
Still an amazing car though, I'm hoping that if they dont ever bring anything like it back with all the new engine tech and make a better engine that performs the same with the vvtL-I system, I'll atleast be able to own a few old ones fully rebuilt so I can keep driving with a 2zzge for the rest of my life. I've gotten so comfortable driving Pontiac vibe gt's the past 4-5 years I can float shift under 3k rpm or at redline, up or down any gear. I prefer to clutch for 2nd cause of the rpm drop between 1st and and, but from 2nd up, it shift so smoothly at any rpm, you really dont need to use the clutch at all. You just need to reduce torque, pop out of gear, get to the rpm of the next desired gear and press the lever lightly into that gears gate until it pops in. Which definitely makes a long stop and go trip, alot more comfortable.
I feel your pain...
I had a 87 gts and "got all the power with a exhaust"....
No power gain... Just noise...
I like it. It's becoming obvious that ICE cars wont exist in the not-so-distant future as more and more anti-emissions bills get signed into law, so I have a strong appreciation for the exhaust note of just about any car. At some point we will reminisce about the sound of a gasoline engine, including the ricer cars.
BEAST!
Haha pretty brutal. Subbed!
I love this car
Thanks for this video. In the celicas description I was gonna buy it said straightpiped. Not really for me either
Yeah, definitely not a good engine to straight pipe. If the car is in good shape otherwise, you can always have a muffler welded in.
Even with a cat, if you have an upgraded exhaust system it's still ridiculously loud over 3k rpm. But if your good enough you can keep it under and really quiet. Took me awhile to learn how but I can even float shift up and down every gear under 3k rpm, I can also float shift up and down on limiter. 2and is the hardest to float into cause of the 2-4k rpm drop. I pretty much only hit the clutch to come out of or into 1st or reverse lol. I just lightly left off the gas, let the rpms drop, and slip it into which ever gear I want depending on speed. I've floated into 2nd from 6th at 55 pretty much straight into lift. I couldn't imagine a better engine and trans for performance and daily driving.
The world needs a 2021-2022 3zzge 2.0L with the vvtL-I system and of course, the 6 speed manual. Hell Toyota made a 300hp 3 banger. I'm sure they could look into rebuilding the vvtL-I system with a block that doesnt explod when you get over 800-900hp.
I mean, it's been a long time since the 2zzge fan Club has gotten anything to make us interested in their new motors. They just slap turbos on everything they say that's economy/performance while abandoning the vvtL-I platform.
It might just be me, but the sound of lift kicking in and the look of the guy your racings face when he realizes you have alot more power and rpm to go for the gears than he thought when lift kicks in.
I've had cops ask if it was modified (illegally modified), I've had friends and strangers ask how much boost it's running saying it sounds like a twin turbo car, only to be amazed when I say its N/A nearly bone stock and that the only possible modifications that could exist in the car are internal engine components that the previous owner may or may not have installed. (Got told my 05 vibe gt was once built for a sema show but got in a bad wreck on the way and was being rebuilt on a non salvage title. Thing was a total peice of junk, and when I got it I had never driven a manual transmission, and the cluster didnt work [was a 10amp fuse I spent a week hunting down threw wire diagrams] so my first 40 miles were done blind with very little experience in shifting or rev matching, 2 weeks later I quit stalling at stops, 2 years later I broke the clutch release plate and only having 1 car and a need to go to work to make enough to fix the issue, I taught myself to float shift, first month of that was a nightmare of highway stop and go, engine on engine off trying to never stop so I didnt need to turn off the engine and turn it back on in 1st launching from a stop every time. Now I float shift nearly every gear gearing up or down. I can float shift at redline or under 3k rpm. 2nd is tricky and floating 1st to 2nd doesn't help performance at all, and I've lost a couple races because I couldn't clutch 1st to 2nd. But since I've started driving 2zzge cars I've beaten, mustang's v6 and v8's, Camaros, f bodys and the new models, challenger and chargers, 3.5s are easy, the hemis are alot harder to beat and all of those cars whip my ass in top speed, but can never pass me below 100 mph. The only one that did was a challenger r/t cause the no clutch 1st to 2nd delay, then I chased him about 20 miles at 110 staying within 2 car lengths the entire time. But unfortunately she succumbed to a busted valve lift seat which completely destroyed the intake cam in the 5 minutes I had to drive to finish the journey. And since I cant just drop 3I into a motor, especially a motor in a busted up body (fenders and front bumper were held on with 4 bolts and zip ties, and would wave as I passed people lol, which was probably why I couldn't ever get over 120mph.)
My new 03 vibe gt has an upgraded fuel system, I dont know what the injectors are but their bright yellow and I've yet to see stock yellow injectors, it came with a 2019 1st place super modified plaque ontop of the battery and I think it has an upgraded exhaust system too. My scan gauge says it's at around 250 hp N/A but that was before I clogged the lift screen after using it a couple times. the story was it wad the guys grand daughters car, so she probably never used lift. I could have broke the lift bolts which would be a pain in the dick to fix but will happen soon and a few other things are dragging and making it sluggish so I'm not sure of its 0-60 time, but I have noticed lift tries to kick in at exactly 6k rpm when its suppose to be at 62 or 6300 in that year model so it seems promising. But for 800$, im fully in love with this one.
I've had so much fun in, and enjoy driving the 2zzge so much that unless they make another better engine with the vvtL-I platform, a manual trans, and operates closely to the 2zz, I'm hoping I'll have enough money and time to fully rebuild a few of them so I can still be driving a 2zz car 30-40 years from now, which at that point it would be a 40-60 year old engine.
A real review
Props
Sound cool man
I also full straight piped my 03 gts....I took out the cats and muffler. When you rev it till 6K rpms it starts to sound like if you have a 2 step car lol....it’s my first car ever so I like the loudness even tho it sounds ricey af lol. Looking into buying a 08 mustang GT and full straight piping and have a beast exhaust of a car😈
Straight pipe definitely sounds better on a V8. The 2zz is pretty brutal straight piped
I've noticed about a .4 to 1 second difference in pulls in my 2zz vibe gt between having a cat, and it having blown itself off. Seems like unless you have a turbo on it, straight pipe makes slightly less power than having the cat on, even if the cat is clogged and overly restricted. I was thinking about a very slight restriction cone just before a glass pack then testing, removing, and shaving small amounts off till it has just enough restriction to make enough back pressure for exhaust scavenging but still have alot of free flow in it. If anyone has tried to slip a cone to restrict exhaust flow and managed to get it to run correctly I'd greatly appreciate any information. Nothing is better than the crack of lift hitting on a straight pipe but theres not much sense losing a second off my 0-60 just to be loud
My mans got a mortar round in his backseat 😂
😂 pretty much!
Sounds sick tho
This sounds good IMO I prefer a straight pipe exhaust on sports cars or a sporty car like a Celica and imo this isn't ricer, Ricer would be doing unnecessary things to your car to make it look like a race car even though its slow as fuck but these Celica's I've saw have hit up to 145mph or more coming from the lil 4cyl and people think 4cyl are slow but ain't true at all I've saw some lil 4cyl beat a lot of V8s especially American V8s but of course everyone knows that American Muscle weighs a lot more than a Japanese Manufactured USDM car in most cases
hey man im in a 2003 celica gts trd completely stock other than ebay cold air intake and i poked out my cat and unbolted the muffler so it has the midpipe basically but it does nothing and its got way more power now. its loud af and sounds like a street bike not ricey at all and sometimes it backfires especially at redline in lift becuz its prolly running a bit rich but the ecu seems to be able to compensate with the fuel trim and its probably a bit rich but its making way more power dude. 6spd manual obviously. pretty sure the 2zzs only come in 6spd.
i have the stock resonator in the mid pipe and it does nothing. the exhaust is being dumped under the car where the muffler unbolts from the mid pipe. and the stock cat is poked out. she shreds now man. mad power/torque now when there was none before. i've got a few videos i could upload but i need to get one of the car parked and revving the exhaust
That is LOUD lol
I'm worried my ears will bleed if I take it to redline lol
The 1zz-fe engines sound pretty good with just a muffler delete. I did it on my 05 corolla, not too loud considering the bubba trucks where I live. It has a deeper throaty sound unlike this
There's another video on my channel that shows just a muffler delete. It was pretty throaty at that point. This video it's just about straight piped, no cat, no resonators, just a straight pass through packed muffler. Most 4 bangers are going to be pretty obnoxious with this set up 😂
YESSSSS YESSSSSSSSSSSSS
I had a clogged cat in my Vibe GT and cut the cat off for a motorsports event on a friday. On monday I took it to an exhaust shop and had them put a new system back on it. Not only is it not good-sounding, it's *seriously* toolshed loud.
Yeah, I just recently had a high flow cat put back on. Much improved honestly and I feel like performance is exactly the same. It may even feel a little faster because the noise to throttle ratio is so much better. Everyone thought I was trying to race with no cat lol
I was the same when I had no cat, and no exhaust may I add lol my cat got detached and everything after that too so I was running straight from the headers and it was like a john deere tractor that loud except it also popped like hell everytime i let go of the accelerator it would pop 5-10x within 2 seconds
😂😂😂
What exactly happened with the DNA? I've heard now from a few people that it didn't hold up.
It started to rattle pretty bad when cold. The rattle would ease up once the car warmed up, but it was really bad for the first 5 minutes of driving every day. Unfortunate because it had a great sound.
Is it bad that I’m liking the way it sounds? Hahaha 😅
Haha, I feel you. I'm exactly like you, I don't like those sounds. Any ideas for a better more Deeper sound without the high end rice sound? Thanks for the video. I have a stock GTS and would like a Deep aggressive sound. I just dont know what to do?
I would just get a good sized resonator. I just added a 10" vibrant resonator and it helped a lot. A resonated midpipe would work wonders. Then throw a magnaflow muffler in at the back, typically going to have a deeper sound than other brands.
Keep in mind, mine is de-catted. That adds a lot of volume. If you still have the cat, that's going to reduce rasp a lot
I don't have much knowledge on this, but I'll look into that. Would a full exhaust system still work pretty well, considering my cat is still there? Since I dont know much about how to weld or anything concering piping and what not.. What do you think? I saw that there's a few full on exhaust systems out there for the celicas that can give you a better deeper tone? Or course.. It'll probably be more expensive eh?
@@Rafaellasvegas It really depends. I bought each piece individually and had a local shop put it in. De-cat and installing everything at once (resonator, magnaflow glass pack muffler and black widow chambered muffler, full 2.5" piping) cost me about $400, parts and labor. Performance gains are much better with a full header back, so I would say doing a full exhaust set up is better than buying a bolt in solution. However, if you leave the cat and go with a bolt on system, I would do the magnaflow catback. It costs about $550, doesn't require any welding. Don't go cheap on aftermarket catback though, it won't last
@@Rafaellasvegas ALSO.. our GTS models are 2.5" to cat and then shrink down to about 2"-2.25" behind the cat. So if you want to stay CARB legal, I would get a 2.5" high flow cat, have a shop weld in an O2 bung, full 2.5" piping behind the cat with a 12" long resonator and magnaflow chambered muffler. Should cost about $500-$600 and will yield some tangible gains compared to a basic cat back system
This video is hilarious
I like it haha
My celica sounded same when I have lost my exhaust in forest xD
I'm super late to this party but say I need a new cat... do you think straightpiping it as a temp fix would be bad?
The car will run better with no cat vs. a clogged cat!
@@THEjameshaner good to know! I finished work yesterday in my '03 and it spit out p0420 at me, so I'm gonna clean it and see what happens
@@THEjameshanerwanted to know if deleted cat gave you any performance issues
@@jeanlouissaint858I wouldn't recommend it unless you have the ability to tune the ECU afterwards. Maybe a little gain on the top end, but I don't think it's worth it without tuning
@@jeanlouissaint858no performance issues though on my particular vehicle
Why not just put a resonator on it to make it quieter and remover the raspiness?
So I have one magnaflow muffler in line, but I'm thinking it may end up being my "resonator". It's a straight pass through design and did not tone down volume at all. I'm thinking that magnaflow paired with a high flow, chambered muffler should sound good. I'm going to try different set ups until I find what I like.
Wait u dont like it?
i tried putting a muffler on it and. it’s still very very loud
I want to hear VVT-L kick in. C'mon!!!
I have another video on my channel with some pulls that I did while the car was straight-piped
She sound right 😂😂
Sounds like a Honda to me
I have a straight pipe no resonaters it back box lol a scaffold pipe literally sound like a Honda lol
Yo bro do you still have any of your interior
Yes, it's all been reinstalled since this video
Ok cool I’m trynna find some interior stuff I bought a 91 celica with a st215 swapped for 400 bucks and it has no back seats and I got a kid
U want the sound
I've seen tests and everage gain of like 7-9 horsepower
Back flow ... how your low end tq driving around town
Low end took a hit for sure. Top end definitely better but the car needs a cat. I think bumping to 2.5" and doing high flow cat would be the sweet spot and leave room for tuning
Keep the cat, get rid of the magnaflow. It will sound so much better just straight piped. It sounds counterintuitive but trust me. Magnaflow makes it sound like a crotch rocket.
How much did you pay for just the straight pipe
$80 if I remember correctly
🤣🤣🤣👍🎶
He not enjoying if he just thinking bout the PEOPEL near by
Just keep it a weekend race car.
Someday. I need a 2nd car first haha
Get a Honda crv for you and the kids :) lol
"I'm a grown man with a wife and kids"
Bro, you're driving a stripped celica lmao. I think a ricey exhaust is the least of your concerns. Also, ricey is subjective haha. I like loud exhausts 😁
Just depends on how you wanna look at it. Insurance is cheap, it's reliable, it's paid off and gets 30mpg. So I think it's a pretty grown up car 😂
@@THEjameshaner my new line for when people say to get an adult car.
Also, its far more responsible to get your speed fix the cheap route (the celica) rather than finance a brand new sports car. Lmao
Also, fwiw. The exhaust doesn't sound bad to me. But a high flow cat flows almost as good as leaving it out iirc lol
Yeah I did that to my Celica and replaced it right away.
Put the resonator back on
No go on the stock one. New exhaust is 2.5", stock resonator is smaller. I did put on a vibrant resonator after this video, but still lots of rasp. Planning on doing a resonated midpipe to tone it down more
Could you shoot flames? 🤔😂
I can try 😂 I've gotten some pretty nasty backfires, but idk if there's enough fuel to get visible flames. Bigger injectors and a tune, anything is possible
lol not for you.
Must be 3 inch all the way no cat and only with a 4 inch back box.
I am 55 and i love them noisy....
i just uploaded some clips of my straight pipe celica check it out
my car is literally louder than that 😭😭
Your problem its not the cat is cause you dont have muffler
Doesn't matter how old you are or how many children you have...men never grow up
* I've seen 80 year old lunatics driving performance cars like they were teenagers
Why not just do it yourself? A cat should take like 30 minutes to put back in. Especially in a Toyota
All welded in. Bolts on at header, then solid pipe all the way to the muffler
Bro sounds like he got cheated on 😐
bro just put mufflers on it
Bro, I did 😂 peep my newer videos
Grown man with a kid n wife? Who gives a fuck. I do too. Just have another fam car duh. My celica loud as fuck. Don't care. Mine sounds way batter bit still
1:32
I thought he said oooooo
But no twas the car 😂
yeah it definitely sounds awful 😂
