KLINE INCONEL project.



One of our development projects on an AUDI RS5 V8.

We designed :

- complete DE CAT manifolds
- manifold back system valvetronic

The system, made from F1 grade INCONEL 625, is very lightweight and high strength,



The sound is very much GT race car on Dynamic mode. But when you switch the car to comfort mode it becomes OEM quiet, the diffrence is stunning. The car can be driven incognito on comfort mode but transform into a race car just with the push of a button !

Manifolds are a mere 2.8 kg each.

Some pics and a video to enjoy.

Price? I am about to pick up a capristo but if you can show your power gains and price

 

what is the name of the singer/song in the video?

 

Our system can be ordered in 2 stages :

1. Manifold + manifold-back system
2. Manifold back system

Both Valvetronic and complete DE CAT.
Mid silencers and rear silencers.

We can fabricate the parts in stainless steel or INCONEL 625.

We haven t made a complete dyno run with all the parts on the car. It will be done and we will show figures here on forum.
The car feels a lot quicker, the most restrictive parts are the manifolds with mani-catalyst. Removing the cats from the manifolds and the cats from the system will give a big power gain.

Prices are :

Stainless steel
Manifolds - 4300 USD
Manifold-back system - 2950 USD

INCONEL 625
Manifolds - 7400 USD
Manifold-back system - 6500 USD

We can also provide hybrid exhaust - INCONEL manfiolds with stainless system.

I dont want to compare direct with competition since it s not fair. We let customers decide.
The way our system is designed, is totally innovative and hasn t been done before on the RS5. You get full sound and power on dynamic mode but after switching to comfort the car becomes very close to OEM.

The music is - Jakwob - Slaves (feat. The 14th)

 

What is the benefit of inconel vs stainless?

 

Formula 1 exhaust are all made from INCONEL 625. It s strong and light.
In comparison with stainless, sidewall thickness we use is 0.7mm . Stainless would be 1.5mm sidewall.

The total weight of the system will be less than 50% compared to OEM. And one of the star features of Inconel - SOUND. You cant hit the same harmonic resonance with any other material. It s very high pitched and agressive .

INCONEL 625 specs :

Inconel 625
Tensile strength 950-1200 Mpa
Yield strength 415-750 Mpa
Density 8.4 g /cc

Inconel tensile strength is increasead with heat exposure unlike other materials.

Inconel manifolds

 

Kliine guys - what did you think of the stock exhaust manifolds on the RS5? Were they a pretty big restriction in your minds? They look to be pretty basic logs...which is odd. The B7 RS4 launched in 2006 went with tri-y headers as stock. Wonder why Audi skimped on the B8 RS4/5. Seems to save bucks but fortunately for us it may leave a bunch of torque and power on the table.

Also what diameter are the collectors and the merge and the catback?

Pretty awesome looking product with some spacey material to make it from. Exciting stuff for the RS5. Congrats on the product launch. Looking forward to seeing some results.

 

Hi Sakimano. I am glad you like our products. We put much effort in designing and fabricating each part.

Rs5 OEM manifolds have a tight space dictated design. And obviously they had a certain buget. The part is very restrictive due to 400 cell manicats. The oem cats have a negative effect on the manifolds scavenge region. Oem manifolds internal diameter is 38mm. If you compare with RS4 4.2 V8 manifolds, the RS5 part is more restrictive.

Our manifolds have 41mm primaries, system size on tubing is 70mm .

We will measure on two individual dynos, one in Europe and one in Australia, both cars have our manifolds. I will post the results !

That is some serious exhaust notes there!

Love the INCONEL! Well worth the investment IMHO to have something so unique



Do you do inconel headers and exhausts for other cars?

 

Glad you like it Velocutytrap. Inconel is unique .

Yes, we make for other cars also. For what car are you intrested?

 

Done on the prototype in terms of hot weather testing and cold weather testing to test for fitment, durability, and reliability?

 

Our prototype is INCONEL 625 made. We tested on road and drag use at +25 degrees and -14 degrees .
Inconel 625 is used for temperature ranges 0 Kelvin / -273 Celsius up to 1200 degrees Celsius which is 1473 Kelvin.

 

Ah. Thank you for the specs. When will you have before and after dynos available?

 

Wow, Inconel headers! Pricey, but that is some premium material. Very cool.
