![mgk - I Think I’m OKAY (with YUNGBLUD) (Sad Version) [Official Music Video]](http://i.ytimg.com/vi/7AC1uqQLIg4/mqdefault.jpg)
Novel catted headers was by far my first choice. I placed an order durning the pandemic and unfortunately because of supply chain issues Novel was backed up with manufacturing. I patiently waited over a year for them to get built, but no joy. MIJ was great, kept me up to date on status and ultimately gave me the option to stay on the waiting list or recieve a full refund, witch I went with. I ended up going with PPE unequal length high flow catted headers. Sent them over to JET-Hot to get their performance coating in classic polish that withstands temps up to 1250 deg. Best of both worlds in my opinion, looks good and substantial power gain with no nasty exhaust fumes from not having cats. Thanks Steven for the awesome video and excellent customer service.
Definitely appreciate the kind words. We always try our best to do right by our customers.
That was an awesome and very informative video!! Thank you for creating one, very helpful especially for noobs like me!
Great video, appreciate you guys!
We're grateful for your sub, support and kind words hoping to make these videos weekly and support the community more with these tech videos.
Thanks for breaking this down for us.
You're very welcome, more videos are coming!
Excellent video and to the point! Can’t thank you enough for posting it👍🏻
Thanks for the support!
Great info...thanks!
you're very welcome!
Great info - this'll help me for potential mods down the road on my LC.
Happy to help! If you have any questions we can assist with just email us at sales@modinjapan.com!
My 21’Is350 , need this ❤
Nice video
Well, I definitely would've gone with Novel and waited a few month's, the idea of a year plus was just too much for me to wait. Ended up with PPE Equal Length, ceramic coated. I'll see how they sound a long with my APEXI N1 Exhaust. I'm not necessarily looking for any particular sound, high or low, but something that let's everyone know "that ain't stock" and makes more power. The APEXI Exhaust is installed and looks amazing. Sounds good too. Not too loud, which is what I wanted. I kept the resonators with the APEXI but dropped all CATS. Sounds like a Vette when you cold start it. Can't wait to hear and see the differences with the PPE EL Headers 🤞🤞🤞🤞.
Thanks again for my PPE Ceramic coated EL headers Steven. About a year now and no regrets
Happy to hear that! Thanks for the support
That's quality
piece of artwork
Totally agreed it’s art
Nice 👌 although what I have is a 09 IS 350 planning for a ISF soon ......keep up the good work
I let us know when you get the F we can always help you out!
Well done Steve!!!! I liked the info and honesty of your content!
Thanks for the sub stay tuned we’ll be pumping these out
Also we sincerely appreciate the kind words helps us push forward 👊
Will do, selling my IS250 and possibly upgrading into a IS500…….if price is right 😂
@@seandoc97 you should do it, this might be the last change to enjoy a Toyota/Lexus V8 going to do a video review on that car soon.
Messaged you guys on IG about purchasing Novel headers for my IS500!
Replied on IG!
@@ModinJapan Will you guys offer the option to step the headers like the F1 cars so they sound nicer? I am trying to find a set for my 1992 SC400 1UZ-FE.
Do a header sound test please
So my question would be, do you need a tune to maximize the performance? Adding intake headers and exhaust would automatically result in performance or since we’re adding, could we see a reduction in performance due to the stock tune wasn’t meant for the upgrades. I ask because I have an IS500 and as of now there aren’t any tunes for it.
PPE with high flow cats (keeps the stink away) and no CEL’s (actualy does not trigger secondary O2’s)
With RR racing 780 SC kit. And a bunch of other goodies like coilovers, Cusco diff etc.
Loving the sound. And the FUN part
How’s the sound with catted PPE compared to stock headers?
@@andersgammelsrd1815 surprisingly not a whole lot of difference.
Slightly more rumble at idle. I never had stock exhaust though. Was always with an X-force header back before.
But my main fear of the dreaded drone at around 2K rpm didn’t happen. Surprisingly you can cruise highway at 70-80-90, and even at 100 at light throttle no drone at all.
But when you get on it…
lol above 3k rpm’s you will hear it sing.
Supercharger also surprisingly quiet. You hear it ever so slightly (additional whistle at idle)
And blow off valves. Only if you shift above 4-5K rpm’s and even that you have to listen to with windows down (they’re recirculating)
All in all, super happy.
Was afraid that.
Let’s just say wife and kids approve.
They’re willing to sit in in and drive with me for an hour to the beach, or mountains in it. So it’s quiet enough.
(And there’s quite picky, wife drives gx460 luxury w/air suspension, so they really know what quiet and plush means)
You can drive thru the normal neighborhood. And no one will notice. Below 2K it’ll sound like a regular coyote. (Though I hate mustangs)
@@11SecSTionStockSnail Thanks so much for your reply. That's sounds good but you're saying you don't know how it compares to the stock header?
@@andersgammelsrd1815I’m saying I got my car with STOCK headers, had a cracked header leak. (Welded it) drove with stock headers for about 10k miles then switched to PPE with cats.
Both stock headers and now are with same X-force exhaust.
With stock headers I used to have an annoying drone while highway traveling (drone around 2-2.5K rpm.s)
With these new PPE headers (same X-force cat back exhaust set up as before)
No drone now,
Same as stock sound untill about 3-3.5K rpm’s
Then a bit louder then stock headers in higher rpm’s
What surprised me is that when car is warmed up, idling at around 700-900rpm’s I can hear individual cylinder firing sequence much better then before.
Not louder at idle. (Listening from the back of the car outside) just more distinct. (Almost sounds like a slight cam, but no loamy wobble cause.
Similar to coyote mustangs at idle (I know I’m gona catch allot of hate saying this lol)
@@11SecSTionStockSnail Ok, thanks for clearing it up! Really appreciate you sharing your experience with it as I had not found any reviews yet. Sounds like something we should order. Gonna see how it sounds with the titanium valvetronic exhaust which is supposed to arrive today, and then maybe add the catted PPE header later.
In the V2 headers are they fixing the tube restriction meant for the dipstick in V2? Saw some photos of V2 for a GSF & compared to V1 confused how it would flow better? Maybe what I saw was a faulty batch?
Are there any headers for the 2007-2017 Lexus LS460?
do you guys ship to CA?
So.. on my e46 2.5i.. I want 2 achieve a subaru sound.. so unequal header.. just not sure how I would go about it.. for that sound, an performance if possible.. I also gave no care for hp.gain.. if ne thing torq.. low/mid is way more important.. any advice would truly be super grateful 🙏 help!! ??? Please!!
Hi
In the UK
After Exhaust headers for my Lexus LS430 2005 , can't find much as "Right Hand Drive"
Any help from yourselves
Thanks
Any info on the new Novel?
Gonna get my ISF this month and debating on what headers to get.
No formal ETA yet but getting closer
What is the new novel header?
What about for boost applications? Can I also get away with having a loop muffler + centrifugal turbo
On request, we can do a custom set up with the catback being a larger diameter for boosted applications. We’ve done it already for one GSF.
I would actually be interested in this, I have a GRL10 getting boosted by next summer but I’d be happy to buy exhaust from you guys
Informative video! Do headers without a tune cause the car to have less power? Do these headers cause a check engine light?
Thanks for the question! In the case of these headers for Lexus you will produce more horsepower as the flow will increase and the ECU will compensate for the increase in flow and you will produce more power. With a tune you could produce even more power so without tune more horsepower, with a tune you’d unlock the full potential. As for check engine light, almost certainly they will cause a check engine light. Hope that helps
You make more power, but knock threshold decreases and your car runs extremely rich. The car keeps dumping fuel in to try warm the catalytic converters that are no longer there. A proper tune will stop this.
I should note too that with increased airflow, you'll lose some exhaust scavenging, so your torque band comes on slightly later.
When I did headers alone, I barely noticed a difference. But the tune made a huge difference.
make more of the please
got lots more planned hoping to have time to shoot real soon!
Can you have headers and still have catalytic converter? I live in a state where u gotta go through inspection frequently
I couldn't say for certain, but if you used California which is the strictest state as a reference point absolutely not. Smog stations have the right to refuse testing if it doesn't pass a visual inspection which is up to their discretion. I've had a CARB Legal Intake on a car be the only thing on my car and be denied by 2 stations, only to have my car tested at the third and pass with no issue.
Y’all sent me 2 passenger side headers…such a headache to deal with now because my RCFs oem headers were already out when this was discovered. I’ve emailed y’all my order number and some pictures.
Hopefully this is resolved soon 😅. Definitely delayed my plans this summer…and caused me to lose over $1k.
I just checked our email and saw your photos we’ll get this handled immediately apologies on the headache and the late reply we aren’t open on weekends, but I do monitor social and YT regularly. We don’t repackage the headers we sell they come to us from the manufacturer labeled, packaged up and ready to ship so there isn’t a reason for us to second guess the work, but apparently we need to now….. Let me get a return label generated and sent to you and we have more of that header in stock so I can get it shipped out first thing Monday morning. Hang tight I’ll respond to your email with this information as well.
-Steven
@@ModinJapan Thanks for the swift response, Steven!
Just sent you an email and will send you a return label within the hour so we can get this handled. I will be talking to the manufacturer about this situation............................ definitely going to be giving a mouthful to them.... Ill check on expedited shipping on the replacement set on Monday so you aren't down for too long.
@@ModinJapan Really appreciated. Also, should I Return the whole package or just 1 header? Also, will I be responsible to pay for shipping?
@@Mr_Odog You're DEFINITELY NOT paying for shipping there or back. We got your back on it, I am sending you a label right now send us the entire thing back same box and everything. I will send a fresh one brand new so I can make sure there are no more surprises. Hang tight generating the label now.
whats more high tone sound?
Any kind of equal length header mixed with any cat back. NOVEL Racing Japan makes the most high pitched note on the market.
Should I add cats to mid pipes after headers? Ty!
Great question. Be sure to consult your local laws pertaining to emissions, but the primary reason to add cats on the mid pipe where the OEM secondary cats are if you have replaced it with an aftermarket mid pipe is to reduce the smell and emissions. After a header is installed the smell of gas will become stronger and some drivers find it unpleasant. You will see a decrease in potential horsepower gain as that section will be choked of air.
PPE has a weld in kit for that situation you can find it here:
www.modinjapan.com/lexus/is-f/is-f-2008-2014/engine-power-3314/ppe-engineering-weld-in-high-flow-cats-kit-for-lexus-is-gs-rc-ppe-935002.html
@@ModinJapancats have different cell counts from 100 cell up to 400 cell. What cell count cancels out about 90% of the smell while not having to high of a cell count because that makes the exhaust quieter.
EPA verified ones are generally 300+ CEL count
IS 350
I think you should do something like this but for the 2IS community .
Added it to my to do list
Thanks bro 👍🏾
Picking an exhaust should be done almost purely on which noise you like the best. Performance differences for any owner who isn’t on a racetrack are negligible.
Wait did you say novel is coming out with a version 2 header?!
Yup first ever globally is arriving next week to us and going to Chris with a GS F it’s redesign for same sound but newer higher flow
@@ModinJapan ohhhh I thought you meant a V2 for the ISF too
@@nickadkins7765 iS F is part of GEN 2 as well it’s a manifold for IS F, GS F, RC F and IS500
@@ModinJapan sick! What's the difference between the 1st Gen in the video?
@@nickadkins7765 GEN 2 will have a higher flow rate by decreasing the amount of welds and increasing the amount of mandrel bends for a smoother and faster flow with the same sound.
Equal length headers make no sense and loses power on a cross plane v8. You have 2 pulses going to the collector at the same time, leading to problems with scavenging and overloading the collector. Realistically you want something slightly unequal length to allow the pulse time to get scavenged by the previous one.
