2 pieces of advice to make this job easier, if you remove the k member it make removal and installation of the exhaust manifold easier and the easiest way to get the o2 sensor routed is to use a piece of wire and thread it down from the top, attach the o2 sensor connector to it and pull the wire up then plug it in.
I had the Manzo exhaust and downpipe but not the header. The stock header I believe is ideal. Have to give your review of the header. Here's a link to how my RX8 sounded after installing the Manzo exhaust: ruclips.net/video/eBbOo51rzAo/видео.html
@@mischiefpwns I can agree with that. There is very little that can be gained from headers on these unless you're going FI. Your car sounds sweet, that's decat right? I run mine with a decat + catback and people are shocked at how low it burbles at idle. They normally sound like hair dryers lol
I fiited the Manzo headers when i changed my engine mounts, BUT i could not get the btacket to line up.. somehow the headers were very close to the gearbox and no matter how much i tried to move them back i just could not get them to line up .. so in the end i left the bracket off !
I installed an exotic speed header on my 2011 RX-8 and there was a difference in power you could start of in second gear and the engine wouldn't stall of course the exotic speed wasn't cheap but it doesn't rattle and the collector set up is better.
Previous owner of my car tried to do this, but failed somehow… now im trying to figure out where. What are like the most common things that can go wrong after this?
Hey man, I've just bought some 'Autosol' for my headlights. As you'll appreciate they tend to fog externally after a few years. I'd seen a few reviews that suggested applying some Autosol and leaving it for a while to then buff out does an amazing trick - I was thinking of wet sanding them down at various grades.... Have you got any input here from your experience?
My understanding is that headers do not provide much benefit at all, as most rx-8 bolt ons. Mazda did a decent job of maximizing hp gains on the renesis.
Hey man, long time no see!!! I have a question: my 8 is not happy about the exhaust. I thought on putting a sports kat, the 200dpi one + a sports cat back but I'm worried about drone, which would drive me nuts since I drive a lot in autobahn. How's your system? Does it drone a lot? Would you recommend 200 dpi cat? And which cat back sounds deep throaty but doesn't drone, if you know any? Thx man
This is an extreme upgrade for the car, but has anyone looked into fabricating a lightweight aluminum frame for the RX-8 to try to match the weight of the RX7? It would make all the horsepower the car has a lot stronger and faster if it can work. I tried looking for any thread online talking about it but I haven't found one yet.
It would be cheaper to buy multiple RX7's rather than try to: * design a whole new chassis from scratch * get the chassis complied and crash tested multiple times This idea is insanely prohibitively expensive both in terms of money and time.
Right He calls adding a factory replacement shorty header "extreme" Then casually talks about building Aluminum 😳 sub frames Like that's no biggie lol 😂
I installed this exact header a couple months ago and the sound seems terrible- like a whistling or fitment, and sluggish at low rpm. Took it to performance shop who said there is no exhaust leak. Not a fan of this header, I prefer mods but I do think stock was better imo. No power difference did I notice. But THANKS for posting!
@@jspvisuals4019 Do you have to remove the header completely when changing the gasket or can you leave it in the car and just lift it a bit to get the gasket in under? I have a Racing Beat header that I put on last year that will get new studs and gasket this summer.
Glad you've said this, I bought a japerformance one, almost identical merge collector. My guess is that's what makes the "leak" noise he was on about as mine also has this same god awful noise
You should have reused your original gasket as the aftermarket 1 is garbage and eventually will blow out but worst of all you can even see in the video it is not the same shape as the exhaust ports I had the same issue once i realized this i put the OEM 1 back on i promises you go change your gasket back and the power will go up
I did this mod to my RX8, it made it to loud in my opinion and did nothing for power I could feel...I've read everywhere that the standard cast manifold actually works well....I swapped it back in the end and I felt no change in performance....with a free flow exhaust and 200 cell cat it just made the noise inside very tiresome. Just my opinion here

Top tier comment there Giggly Puff :)
Really enjoy how quickly to the point you get to with showing things and telling what needs to be done.
I´m happy to see your videos again, are really useful to make a lot of maintenance and modifications on the RX-8 😉😉
Thanks and keep pushing 💪💪
Great to see you be back! Been missing your videos

GENIUS
It's My first Mazda and I am loving it
You updated the car so much man looks beautiful 🔥🔥 enjoy the car bro be safe God bless.
Thanks man! I'm glad you like it :)
How many of you have the MANZO headers, and what is your experience?

i have had them on my car for about 6 months atm with bhr mid pipe and hks hi power single exit. sounds pretty good not to loud until you step on it.
Hey Alexi, you didn't have to retune your 8 after the header install?

Sensational video. Sounds better for sure. A de-cat would be loud and probably induce 🔥
2 videos in a row!!! We need more videos !! :)
I installed an exotic speed header on my 2011 RX-8 and there was a difference in power you could start of in second gear and the engine wouldn't stall of course the exotic speed wasn't cheap but it doesn't rattle and the collector set up is better.
In Australia we like your videos
Hey that engine mount looked just as happy as mine XD
Omg that sound is too good, amazing job . Your car is getting more and more pOrn 👍
😍 yes keep uploading more
When is the engine mounts video coming?
With the new header sounds even better, but is there any difference in terms of engine bay heat or performance??
Glad to see you and your car back on the channel again! Do you have any thoughts on hybrid 6 port exhaust manifolds?
At 5:20 I see a hose with a red sleeve. What is this hose and where does it go? On my rx8 theirs just the nipple and it sucks air very loudly.
I’m running BHR engine mounts, good option if you’re in the market.
Nice to see your videos . o was waiting all this time for a new one . is this header 76mm . i guess very soon it will time for dyno .
I’m thinking on installing a header but, Is there any difference in the sound inside the car?
If it is too loud to drive on the street
Thank you
What's the benefits of removing the air pump ?
Less engine bay clutter. If you delete the cat you don't need it anyway. You will get a CEL from time to time though but it's no big deal.
Hi. How are you satisfied with the Manzo manifold after 8 months ? What about quality ? Do you recomend it or stay with the OEM ? Thx
Stay with OEM....deffo...way to loud in side,very little if nothing gains in my experience
I have to ask wouldn’t stainless steal crack due to the heat of the engine? I know that the oem is stainless steal.
Sorry cast iron
Previous owner of my car tried to do this, but failed somehow… now im trying to figure out where. What are like the most common things that can go wrong after this?
Is that sealing paste oxygen sensor safe?
Is there any power gain from aftermarket headers? Few HP probably?
Nothing you'll notice.
Slovenia? Dobar Dan!
Dober dan!
Nice, cat link pls?
What is the rattle that we're hearing then? Why is that normal?
What improvements did u get?
Are they the same for series 2?

does it make more power?
You will never notice it. It's more of an efficiency mod.
I have a 1st gen rx8, if I go above 6000rpm I get a power increase, but i feel a "bumb" when i do it. Do you know what the problem is?
My understanding is that headers do not provide much benefit at all, as most rx-8 bolt ons. Mazda did a decent job of maximizing hp gains on the renesis.
This video is perfect for someone like me who isn't really looking for gains, but looking to fix an issue. I believe my stock manifold is cracked.
I'd only change bolt on parts to save weight if I want to shave more time.

cut the cat. it offers nothing of value and should it clog, it will blow your motor.
@@felixwankel3989 I wish I could. If I wanna be legal, which I want, kat is a must
@@vhpublic1 high flow cat if you're lazy. Have a cat for inspection and take it off after with a midpipe like for the other 364.5days
Where is your location i wana bring my mazda rx 8 for replacment of exhaust manifold
Any change in power?
No, maybe a slightly better throttle response but cant really tell
What is this spoiler called?
M1

Is this car still on the road?
Yes

Then casually talks about building
Aluminum 😳 sub frames
Like that's no biggie lol 😂
@@johnj2496 I meant the aluminum frame would be extreme
Is that Mazda a v6 or a v4
V12
How can I get one like that
There's a link in the description of the video
Si ma la benda sul collettore? Dai
this header will go before his engine goes, depending on some factors
the links doesn't work unfortunately m8
replace the battery to a lighter one

I also uninstalled it and put the stock gasket on which I think is better than the one they provide - my car has like no km on it so its in good shape

Sounds the same to me. Think I'll save my money lol
Is it worth buying a rx8 ?
If you have a very good paycheck and extra money then yes, if not, no.
Let us be honest, you choose it because it was cheap.
☹️☹️☹️the merge collector is really bad on these

Yeah, no. WD-40 isnt a penetrant. It's a lubricant. You'd wanna use something like PB Blaster or Aero Kroil
Not a fan of the outlet only being 2.75 inches. Should be 3

Hi i know its off topic by i got to ask if anyone has expirience whit an rx8 engine code P2096.
Good video but you will restart the work because this gasket manifold is a piece of shit and it will be destroy very quickly.
Are you Jewish?
Please next time make a vlog about how to replace the entire clutch of Rx8.
