Exhaust Materials Explained! *Pros & Cons*

[@talkingmods]

What kind of exhaust do you guys own and are you happy about the materials used? Also, forgot to change the text for the bonus but it's called Ceramic Matrix Composite (check the description for more info).

[@talkingmods]

Thank you for putting that together :)

[@_Car_Ideas]

Every helpful! Thanks for the time stamps!

[@blackrifle6736]

*Ron: Details matter. Inconel, first used in aircraft gas turbine hot sections: 1.4 kg = 3 Pounds because 1.0 kg = 2.2 Pounds. Love'ya and Cheers!*

[@juancl3651]

That's aluminized steel not aluminum my guy

[@talkingmods]

thx :)

[@bansheemopar]

Yeah, he is talking like he is an expert, and does not know the difference between aluminized steel and aluminum... That Video is a total waste of Time...

[@neitevezana9263]

Thanks for sharing such informative content.

[@talkingmods]

Glad it was helpful!

[@aksel487]

Inconel exhausts are lighter than titanium because you can use very thin wall thickness

[@bongwaterbojack]

That carbon composite stuff seems incredible on paper. Though my intuition makes me doubt it having a terribly nice sound.

[@talkingmods]

It is, and it's real for sure. I've held it in my hands ( felt like nothing, and they have sold it as mentioned but just a limited amount) hoping economies of scale to get prices down. No idea on sound it was only used as a tip for now. Then again titanium sounds pretty terrible, but quality exhaust companies seem to really know how engineer the sound correctly.

[@Pocketbassist]

What kind of gauge steel vs aluminum are you speaking of? In my experience aluminum is way heavier than steel. 16g to 16g

[@kennypham8585]

very nice informative video.

[@allen724]

Thanks for the informative video. Are these exhaust temps the maximum measured temps which would be the headers? Asking because I’m considering a titanium catback exhaust for my C8, won’t be tracked. Is this still going to break in like 2-3 years?

[@talkingmods]

Glad you enjoyed it, Yes, the temperatures are a range, the headers are typically going to be the hottest area. On the C8 though you can definitely get a nice titanium exhaust (Akrapovic just released one) and those are going to be durable, not break and last you well over the 3 year mark, but likely the lifetime of the vehicle. When that time comes, hopefully you know who to hit up to get it for you ;) (we are an authorized Akrapovic dealer).

[@codymullins2258]

Could you do an update video on what you can and can't do in cali/the status of the rpm act?

[@talkingmods]

Hi Cody, when I have more information (mostly through SEMA) I will look to do a status update. The Can's and can't do, are in the CARB information site - ww2.arb.ca.gov/ I can tell you that cracking down has been very stringent (latest company dynojet just paid $2.1 million to California a few days ago).

[@bongwaterbojack]

What you can do, is leave.

[@sultanm.aldhaheri8539]

Which is better for performance stain steel and titanium?

[@talkingmods]

In automotive terms, Titanium would be better performance for being lighter so performance for the vehicle ( but in terms of horsepower performance, they should perform the same, it's about the velocity of how fast the gases are expelled for the performance.)

[@Kels14B]

I think you just saved me $300 for a YZF R1 mid pipe mod.

[@averyzaliasylvia4026]

Does the material itself improve performance other than being able to handle higher temperature?

[@talkingmods]

Yes, weight reduction helps improve performance. The lighter the vehicle is, the easier it is to accelerate, decelerate it, handle etc. Weight is always one of those things that performance if it can attain should try to achieve.

[@mreroot]

Is there any chance of a video comparing same material but different gauge? Growing up around hot rodder's I've heard stories of everything including using driveshafts to finish exhausts.

[@talkingmods]

Gauge makes a difference for sure, I don't know if I can do a full video on it, but I'll try to put it into a Q&A. Thanks for watching :)

[@blackrifle6736]

*Ha, ha! I remember that insanity. I also remember annoying ping-pulse sound from thin, crap-grade headers on 11:1 CR SBCs. Now of course we have 14 gauge tubes with Dan Swain's ceramic coatings and woven-titanium wrap to stop that crap at the source. That's progress. Cheers!*

[@antongeshelin5362]

Inconel is not very hard to weld. Most TIG rods used for stainless welding are Inconel 600 or 625. Although, it is slightly heavier then iron, a paper thin tube 0.5mm or 0.019". In the end, Inconel Exhaust is lighter then any other material. The problem is initial cost at $200 per foot and that it is hard to bend and cut with usual tools. It cuts and bends just fine but it takes a lot of force or a carbide cut-off wheel. Inconel turns green (color of Nickel oxide, this is why emeralds are green) in use. People use 1/8" stainless pipe for turbo headers because cheap 304 stainless will corrode, form scale and flake off. 321 or 347 stainless is best for exhaust but it is more expensive. Do not forget that exhaust comes out at 850 to 1,100C, but it cools rapidly, especially after a turbo. Hence, there is a good case for Inconel + stainless exhaust. Aluminum does not corrode under normal conditions, even at higher temperature, because it forms an oxide layer (which is the second hardest substance after diamonds and what the sapphires and most industrial sand paper are made of). However, chlorine (as in the table salt and what is spread on the roads to melt snow) will quickly dissolve aluminum oxide and react with aluminum at any temperature! Chlorine will attack steel and most stainless, just as well. For the best exhaust sound just use copper or bronze pipe at the end of the exhaust (copper and silver alloys are used for church bells and musical instruments). It is cheap and more rust resistant then stainless.

[@talkingmods]

interesting, appreciate the feedback :)

[@DouEditz]

Thank you man

[@talkingmods]

You're very welcome!

[@bobbyrios2k223]

Amuse euro s, i just need to sell a kidney 🤣

[@talkingmods]

It's a great sounding exhaust but honestly as I mentioned I'd probably stay away from it, it's likely life is only up to a year.. then again it's sounds so good.

[@bobbyrios2k223]

@@talkingmods yeah, it sounds amazing. Didnt know it wouldnt last that long though. That sucks lol

[@junechris]

The price for ceramic matrix is "One Million Dollars" (Dr Evil)

[@talkingmods]

LOL :) probably right for a full length exhaust.

[@paulhetherington3854]

III pip = required by: Law integrated - in the EFI || Injector - piston - rod (R'''atomic architect!) Or II pip! Slow react - port ! Suspect to - oil won't burn - correctly! Unles - match burn rate - injector!

[@christiangreen612]

how can you talk about inconel exhausts, and not mention Kline innovation?

[@talkingmods]

Oh dang forgot them when I made this, sorry at least it's in the comments. I even own a Kline on my own car.

[@nickt1301]

Only problem I've got Is Aluminum doesn't rust I know this because I worked at an Aluminum refinery all are Aluminum stayed outside in the rain and snow and non of it had rust ever steel rusts Aluminum dosnt Aluminum just burns out fast because of the low melting point

[@palo3533]

Stainless steel exhaust is lighter then aluminium steel ? 😂 That’s not true.

[@talkingmods]

did I say that oh dear must have been a slip.. :) hopefully rest was clear.

[@FAbChild1]

You said aluminum will rust lol 🤦‍♂️

[@aksel487]

It corrodes, rust is a form of corrosion
