Don't Buy Z1 Motorsports Metal Gaskets Here's Why!

[@ERICSDIYGARAGE]

This is my personal experience with using these gaskets with that said I would not recommend them for your vehicles

[@Cha2314]

Z1 was great with shipping that’s why I was quick to jump on these and the reviews weren’t terrible. Maybe the leaks are more prevalent when you have a decent volume exhaust.

[@ERICSDIYGARAGE]

I recommend swapping them out for concept z extra thick gasket. Rtv won't hold up for long

[@Cha2314]

@@ERICSDIYGARAGE they just replied saying not to use rtv so I’m going with your suggestion. Exhaust sounds like complete ass now.

[@ERICSDIYGARAGE]

That's funny because they told me to use copper rvt

[@Cha2314]

@@ERICSDIYGARAGE what I’m getting is the issue with these gaskets is that the require and absolute flat surface to work properly. Issue is that it’s never mentioned and they shouldn’t be advertised as replacement gaskets if that’s the case. Exhaust hot, metal warps slightly when hot.

As a viewer I really appreciate the fact that you do your best to present an honest assessment of the work and products you've had experience with . Thanks Eric.

[@ERICSDIYGARAGE]

Thank you I appreciate that

[@pearlywhitehk]

Just installed their test pipes, the O2 flage bone leaking...plus the gaskets. Thanks for making this vid and affirming my leaks from Z1

[@latino914]

You're right on with this! I had this problem with their gasket and even spoke to them about it. They were playing dumb saying they haven't heard of this issue and that my flange must be warped. Switched to the Fast intentions composite gasket and no more leak. Fast forward to now and I have a leak even after I put a new fast intentions gasket. I might go the CZP route, or was thinking of doing the RTV ultra copper route that people have done. I saw a video where a guy uses the oem o ring type gasket for the cat to header gasket and he had test pipes. But I thought the Oem o ring cannot be used with and aftermarket converter....

[@ivannz3370]

Great video man I’ve struggled soo much with my car because of this problem 🔥

[@ERICSDIYGARAGE]

tell me about it bro it's soo annoying but the gasket I mentioned from concept z works flawlessly

[@beenova3247]

I refuse to doubt anyone who fix their car on the side of the road. If you say the gasket suck no argument from me!

[@ERICSDIYGARAGE]

thanks for the support!

[@beenova3247]

Thank you for the great videos

[@ZeroFX32]

Thanks for this video! I am refreshing my entire exhaust system and just ordered Z1 gaskets, but saw your video and quickly cancelled the order and purchased the CZP gaskets. I always had leaks with Z1 gaskets but they have so much hype that I supposed I was doing something wrong, because "these gaskets are perfect" but no... Thanks again

[@ERICSDIYGARAGE]

Yeah everyone hears z1 and they automatically think they are the best but im slowly reazling that they cut a lot of corners

[@ZeroFX32]

@@ERICSDIYGARAGE you are right, they made really good parts but not everything is great. Their CSC delete is known to be bad (I purchased one and luckily sold it before installing). I went with my boosted G37 (see my videos) to get an issue fixed and they masked the issue, never actually fixed it. It ended up making big power and much better than it was before, but not fixed as I expected. They helped, but didn't actually solved my issue. I went with another tuner (remote e-tune) who took HOURS to explain me a lot of things, and if I need help he will spend as much time as needed to continue helping me without asking for extra money. I had high hopes for Z1 but they are just another place for Z and G, a good one but not the best as some people think.

[@Jekisprezenyk]

Glad I found this video even though it's been a year since it came out. My ISR exhaust started having leaks at the 3 in connections (probably cuz Installed it in a parking lot by myself lol). Been looking into different gaskets to see what all the difference was. I found some extras I had lying around so I'll see if that does the trick and if not I'm hitting up CZP

[@CleanCarbonZ]

Great video .Yes those Z1 gaskets are trash. You have to have a composite gasket to crush to form a seal with Exhaust type gaskets.

[@Cha2314]

I wish I found this video before just installing mine. Went from a slight exhaust leak from a failing OEM gasket to the nastiest sounding exhaust ever. I’ll try the RTV with the Z1 gaskets but I wish the website said to use them. My test pipes came with metal gaskets and said rtv is not necessary and they don’t leak.

[@ERICSDIYGARAGE]

Yeah z1 has taken my reviews down from the website I don't think they want negative reviews on there very shady of them. Sorry you had to go through the same thing

[@rvpineda8260]

I was about to place a order for some Z1 gaskets. Thank you for the good video 🙏🏽 PS: I order some OEM gaskets instead

[@VQSNOW]

Only used the 3 bolt for my test pipes still great til this day ! I used concept z for the 2 bolt bc they are thicker

[@chiliesg37s63]

I order these as well and they suck ass ! concept z performance have thick gasket brought them installed them and haven’t had a leak since definitely recommend those you’ll see how thick they are

[@lightcario1471]

Was it the vibrant performance ones ?

[@drizzetsrevenge]

You're having these issues because your exhaust flanges are warped. Metal gaskets don't really crush, that's part of the reason they're so durable. I've had them on both of my cars for nearly 100k miles collectively, and haven't ever had them leak. If you're getting composite gaskets to seal but metal gaskets aren't, you should quit overtightening your exhaust hardware and warping your flanges.

[@ERICSDIYGARAGE]

I have a hard time believing that all my flanges on my car are warped. 1:09 you can hear both the header flange and the y pipe flange leaking. Let me just remind you that I installed a new isr y pipe and test pipes so your saying they are Also warped? before I had the stock cats on with the circle metal o ring and the flange never leaked.

[@drizzetsrevenge]

@@ERICSDIYGARAGE warped flanges from test pipe to manifold are very common to see warp. They're long flanges, and welding produces a lot of heat around the entire flange. Cheaply made test pipes almost always have flanges that aren't warped before you even install them. The fact that yours are ISR almost guarantees this. Part of the reason they use those composite fiber gaskets is because they crush when the flanges are tightened, and seal better when crushed.

[@drizzetsrevenge]

As yourself this: if your flanges are true and so is the gasket, why did it leak? The only answer is that something wasn't flat. That's how exhaust escapes. There HAS to be a path, or it doesn't leak, and those gaskets certainly weren't gouged, bent, or damaged. 100% your flanges were the issue.

[@xan_z3428]

@@drizzetsrevenge yeah the z1 gasket isn’t flat like it needs to be. They have rigid edges and too much of a lip allowing air through them because the gasket sticks to far out on the lip. Which hints why air gets through them… and also he has explained why air gets through them already and also if you recalled right. Z1 themselves even said you need a copper piece for it if it does not seal which is not included with the gasket…

[@ERICSDIYGARAGE]

I give up on trying to convince z1 fans

[@johnnyboii6193]

Just bought a set of these gaskets to go with my test pipes and sheesh I wish I would’ve listened to the warnings. I have spare gaskets from berk technology and will be swapping those one for my high flow cats

[@ERICSDIYGARAGE]

Sorry to hear that man z1 is really over hyped

[@synaptik111]

Great information. Has Z1 fixed this issue since you made this video?

[@ERICSDIYGARAGE]

They don't believe the gaskets are the issue they say it's warped flanges. If that's the case everyone has warped flanges

[@jaydendelaney4276]

This video is exactly what I was looking for I tried everything to seal my test pipes on my vhr

[@ERICSDIYGARAGE]

What gaskets did you use

[@jaydendelaney4276]

@@ERICSDIYGARAGE I’ve tried the ones that came with my eBay test pipes it was like the one you showed at the end with the holes I blew out 2 sets of them I tried just copper rtv that only lasted an hour I’ve tried z1 I threw them out and now I’m getting these for sure

[@ERICSDIYGARAGE]

So far they ate holding up just fine hopefully they work for you

[@jeremybaldwin6325]

How do you feel about those gaskets a year in? I was about to buy them and luckily did a search and saw your video. I was thinking using OEM for all 2 books and the concepts Z 3 bolt for header gasket. What are your thoughts? Or concept z for all of them? Great video!

[@ERICSDIYGARAGE]

Oem for the two hole is the way to go. Concept z for the 3 hole header flange is the only way it will not leak the do bend easy but if you install them correctly they will work

[@ScyzenGR]

Coincidence this video was created, I bought z1 gaskets recently and for me these aren't sealing well especially the 2 hole gaskets. Did some looking to see if I was the only one.

[@ERICSDIYGARAGE]

from what I'm seeing in the comments it's a 50/50 chance that they will work

[@eduardoFIFA]

damn I have been told by mechanics it's a good idea to use RTV along with your metal gaskets anyways. Maybe you're both right, the gasket should seal better but using RTV also is not a bad idea and that's not just Z's or Z1 gaskets

[@ERICSDIYGARAGE]

Oem gaskets from nissan seal without the use of rtv

[@eduardoFIFA]

@@ERICSDIYGARAGE Well that's true, but I'm dealing with and issue right now and I have Z1 gaskets. But when I took it to a shop they took a quick look for a leak and said they don't think it's an exhaust leak from what I did. It makes almost like a hissing sound after you rev the car. I think it might be the stock y pipe

[@mudshotit]

i’ve been through 2 this year on different pipes🤣 started on the left now it’s the right 🤦🏾‍♂️

[@masterofnone7846]

Remflex gaskets are great!

[@TheBarbersbarber]

Yes parts videos 👌

[@nahumrodriguez89]

The thermostat gaskets also suck.

[@strictlyvicious]

I ran them with orange rtv and they never leaked ever and also u have to it flipped on the right side as well

[@ERICSDIYGARAGE]

That's the problem you shouldn't need to use rtv. What's the point of using a expensive gasket if you could of just just rtv by itself.

[@silent_torseeker7741]

I was about to order z1 but youtube has steered me away from them Not that is bad but there are many more convenient options

[@silent_torseeker7741]

Hey i have a question will oem gaskets work the ring ? I ordered czp but accidentally only orderd 1 will ring work for rhe other test pipe that never leaked

[@jaredgrossnickel5103]

Did you have to use any sealant on the thicker gaskets or did u just put them on and they were good

[@ERICSDIYGARAGE]

They were good

[@fair2ladyz370]

They Don't work, i have the same problem on my Single Turbo 370z.

[@dannybartlett4225]

you could make your own thats better mate

you need ultra copper sealant.
