- In this video I go over how I built my custom exhaust system for my 2001 Lexus GS300, and I show some before and after shots of how it sounds. At the very end, I give you my honest opinion of the final result.
Enjoy! - ยานยนต์และพาหนะ

Very nice! Great job building/welding and installing!!
Thank you!
Nice job, sounds good. I own a 98' lexus gs400, my everyday driver for past 8 yrs., only have done a muffler delete so far, love it!!
Thanks! And nice! I actually would love to own a GS400 haha but I love my 300 as well
Different engines one is a v8 and the other one is a 2j
Nice videos deserves more subscribers
Thank you!
Love your video men, I wish you do more videos on the Corolla
More are coming on that car, stay tuned!
Nice Video! Since you deleted that one O2 sensor did you check engine light come on?
Yes. And it's still that way. Lol I haven't had a chance to drill and tap that pipe for a new O2.
Oh ok was wondering
2 questions
1. I’m ordering custom pipes for my GS 430.. will it make sense to ask them to make my pipes really quiet but with a strong growl when I rev it?
2. I notice your fog lights are clear with LED bulbs, can I purchase mine that way or did you put that together?
They all come clear (at least here in the US). Anything else is aftermarket. As for bulbs they all come with halogens but I like the LEDs better.
As for exhaust... are you having a shop do it? Or buying pipe and putting it together yourself? Either way you have options... you can delete the third cat like I did, that'll increase sound a little. You can also delete the resonators which i recommend if you want nice crackles. That will increase sound quite a bit. As for mufflers you can do with a turbo muffler which is the quietest option, but still louder than stock. Next level up you have a fiberglass padded muffler which is one notch louder, then you have the straight through muffler, then a chambered muffler, then no muffler. So do your research but know that you will most likely experience some drone no matter what setup you have. So do research and see what you like then test it out. That's the only way to know.
@@AutoFixYT again, thank you for this help! I'm actually having the pipes custom made so I'll definitely throw those ideas out there when making my purchase.
I guess twice the mufflers almost twice the Mifflin capability. I'm curious if you dynoed it. It sounds better after the 300 miles I'm guessing computer adjusted its tune. For the dyno in this situation I'd expect 15rwhp or so on NA.
Yeah I was going for something quiet-ish since it's the family vehicle, but something that sounds good still and I've definitely achieved that. I have tried countless times to capture the sound on video but no matter what I record with, it won't come through. In person it's a very deep throaty rumbly tone but even with all the muffling it's not too muffled whatsoever. I am impressed with the sound actually. When the mufflers were new it was definitely more muffled. Now the fiberglass has probably lost its sound absorption capabilities
I know this video is about exhaust, but I have a question regarding your wheel setup. What wheel/spacers are you running in the last clip where you give your opinion after 1500miles? The fitment looks really good and how it should look stock
I agree that that is how the fitment should be from the factory haha
So those are actually stock 350z wheels. Mid 2000s 350z. They're 18x8 with a 30mm offset, not staggered. In the back I have 1" spacers to line everything up perfectly. As for tire size, I had 225/45R18 tires that came on those wheels and I hated the look and the feel. So I now have 235/50R18 all around. It's got plenty of grip to be thrown in a corner and it will just hook and turn (no, it won't really drift but it's NA open diff so you're not drafting that thing lol) and on the highway it feels A LOT more stable at higher speeds. We won't mention specific speeds but let's just say I didn't know that car could feel so smooth and stable at certain high speeds.
Also i should mention in the front I do not have spacers. Just the wheels as is.
Oh and I did have to roll the fenders in the rear. That lip that Toyotas always have that pertrudes into the wheel well was rubbing on the tire.
Hope this helps!
@@AutoFixYT this helps greatly. I was planning on getting 235/45R18 and spacers in the back, but I might go up to 235/50R18 since it looks so natural. Thank you
Honestly I think a 50 sidewall will look so much better, it literally looks to me like it should have looked from the factory for a perfect street fitment
hi
nice video :)
Thank you!
Hey what did you do with the mid pipe sensor? I know the pre 00’ gs never had them
I cut the old one out and I have a new bung and sensor to out in the same location. I haven't done it yet though.
I'm sorry I will admit to skimming through to hear the sound but how do you make it loud but not a fart cannon? I straight piped my GS300 with true duals but it sounds really bad.
These engines don't sound good straight piped unless they're boosted. As you can see in the video and in the thumbnail, I kept the original primary cats, deleted the secondary cat, kept the original resonators, and changed out the original mufflers for super turbo mufflers. The entire setup is not loud. At least not to my standards. It does however get noisy when you're heavy on the throttle. And it has an amazing deep tone. I also added an H pipe right at the beginning which promotes low end frequencies. An X pipe is more for higher end frequencies and can make an engine sound raspy.
Hope this helped!
@@AutoFixYT thanks! for reference this is how my car sounds right now
th-cam.com/users/shortsZ4dTwfSx8NE?si=LhGpso7n76eHWb-N
I will cut off some resonators from another car and put them on.
@evannniesen460 oh yeah that's bad hahaha get some resonators on there. Buy the longest cherry bomb glass pack you can find and weld it on. Maybe even a straight through muffler to even out the tone
@@AutoFixYT will do thanks very much!
I just bought a GS300 and truly have no clue how aftermarket exhaust setups work but I’m going to follow this guide when I upgrade the exhaust in Jan.
My ideal exhaust is something with a loud startup but when I’m on the highway doing 70-90, I don’t want any drone. Any recommendations for something like that?
Great video btw
Awesome! These are great cars, a lot of fun to drive!
That's gonna be hard to achieve. I don't know much about pre-made exhaust systems but that might be your best option. Anything custom will have drone that you'll have to remove with Helmholz resonators. Pre-made exhaust systems can often take care of the drone but they are also very expensive. I don't know which ones are best for this car because they are so expensive that I didn't even look at them, I decided to build my own right off the bat. So do your research. Pretty much any exhaust sounds good on a 2JZ so you can't go wrong, the only problem is drone like you said.
My setup that you see in this video does have some really annoying low frequency drone, between 60 and 70 Hz. Only under 1800 RPM at low throttle input. I plan on fixing that with a Helmholz resonator eventually. These cars sit at about 3k RPM at 80MPH where there is minimal drone for me. But... every exhaust system is different and will react different to certain frequencies.
Hope this helps!
By drone, you guys mean, the rattling and grumming noise that Resonates throughout the car right?
Because I too bought a GS300 recently, the exhaust is in pretty good shape, but I want to do muffler delete, just hoping it will not give the "drone".
Yes that's wgat drone is. A very loud, over amplified, kind of sound that is created by the frequencies of the exhaust note combining with the frequencies of the vibration of the chassis as well as the shape of the interior of the car, which makes them bounce around in such a way in which they basically self amplify. On the outside of a car you can never hear that drone.
A muffler delete shouldn't give you much drone but I guess I wouldn't know since I've never done it on that particular car, so you'll have to try it and see what happens haha
@@AutoFixYT I'm really taking these things very slowly. Friend of mine has a IS250 (2007) did some crap to it that the car just makes a racket. it's just unbearable to sit in it untill like 50mph, where the sound dampens. he claims it's only a muffler delete. im pretty sure he got his resonator or cat stolen, maybe even both
@@mohammednurul9380 Well there's a huge difference between no muffler and a straightpipe or a cut downpipe lol
Honestly no matter what you do a 2JZ will sound good, it just might get more or less raspy depending on the setup
How many hangers hold up the exhaust I only see like 2
I’m Im the proccess of straight pipe
6 total. 2 on each muffler and 2 on the resonators.
And nice! Hope it all goes well!
Could an exhaust leak cause a code reader to say you have no CATS??
Well... yes and no. It depends on the code. What's your code?
Do you know what's the original size of the exhaust pipe?
2.25" all the way back
@@AutoFixYT Thank you 👍
Which weld is that?
I'm using a Harbor Freight welder, the brand is called Titanium. Highly recommended as a beginner welder or backup unit.
*That was one Frankenstein exhaust system* ( not to mention the resonators were used AGAIN LOL )
Hahaha the old one was definitely patched several times but thats nothing compared to others I've seen
@@AutoFixYT Lol. I'm totally surprised of how quiet it was after you put it back together. Good welding! You can come down I95 and do mine, I just the need installation 😅😑
Yes I was going for quiet since that is the family car. One day when it is no longer the family car it will get louder, but this setup actually sounds really good. It has a quiet deep toned growl to it and it does get somewhat noisy if you floor it. I'm very happy with the results of my creation lol
@@AutoFixYT If it's functionality is working, it's a great creation...I noticed you skipped pass excepting that job offer lol. Like I knew you would because I asked before when you first pulled the engine out 😂
Haha yeah I don't do work for others haha I barely even have time for my own cars lol
I found obx headers for that car for less than 1000$
Nice, that's why i didn't do headers. I was on a budget and they are very expensive lol
what were the improvements time wise on the dyno?
Butt dyno says it feels the same lol but sounds a lot better
@@AutoFixYT yeah sounds amazing, might do this myself soon aswell , i like how it sounds eith the resonators, wondering how it will sound without
@@AutoFixYT can u link me the muffler and where u got the piping ?
Having had this setuo for almost 2 years now (finished building the exhaust system at the end of Feb 2021), I can tell you the following things:
- the piping rusted out badly. Not sure if I'm gonna bet more than another 2 years out of it before it falls apart. So if you live in the rust belt, go with some stainless steel or have it powder coated or painted or something
- the sound was great at first but after about 6 months it really refined and now it sounds even more amazing! It has an aggressive roar to it but it's quiet. Love the sound. Very subtile but still nice
- this exact setup will have tons of low rpm drone, especially when the exhaust warms up. And the hotter it gets, the more it will have it. Mine has two peaks, the main peak being around 1300-1400 RPMs, super loud and annoying. The second peak around 2500, not that bad but noticeable.
- I removed the secondary cat so for the first few minutes the exhaust smells until the primary cats warm up enough.
But... Even with all the negative points it's totally worth it because it's sounds so good lol.
This is my family vehicle so that's why I kept the resonators on there. Gotta keep it quiet. As soon as it is not the family vehicle anymore, I'd like to cut the resonators off and just run the mufflers. Should bring the noise up a little but not too much. Right now the combination of the two as well as the H pipe remove all the high pitched frequencies so it has a very deep rumble.
Here is a link to the mufflers I used: amzn.to/3VY6LCi
need hks hi power mufflers
Yeah those would be nice. Expensive though. Maybe in the future
Delete the mufflers for more tone
If it was my car I would have a totally different setup but this is our family car/my wife's. And we have a baby so it can't really be loud. My two cara are loud though lol
V8engine？？ I'm Japaneseだよ😊
2JZ-GE
Ah a northern car.
Very much so lol
