How To Get That F1 Sound

Gordan Murray’s T.50 and Aston Martin’s Valkyrie are equipped with bespoke heat shields…

Thanks!

I'm kind of baffled as to why the S-Line unvalved would sound drastically different from the Kline with valves open. Since both are unmuffled X-pipes.

I'd like to have the option of valves but it sounds like the S-Line valves aren't very effective.

I also have no intention of swapping out my stock 2nd cats yet (have Fabspeed headers) so I'm kind of worried that Kline won't give the scream that I want that S-Line will give.

I don't mind loud all the time, but it would be nice to do my neighbors a favor.

 

I mean, if you feel $9k+ is reasonable.

 

Check prices from BlackHawk Japan

 

Better for sure. But with shipping + tariffs it's going to be up there.

 

Going from 200 cell cats to 100 cell cats shouldn't change the tone at all, it should just make it louder unless I'm mistaken.
I actually don't want it getting any louder.

The way they describe this header seems in line with how I described my Larini a few posts ago. "fuller exhaust note" and "better mid range response" are the two main things I mentioned the Larini did. Specifically I said "sound did get smoother/richer" and "I was actually caught off guard with how quickly it accelerated"

This gives me a bit more confidence in my descriptions/experience considering this manifold seems quite similar to the Larini.
Both are 4-2-1 stainless with inconel shielding.

I've attached some pictures of the Larini btw. It really is a beautiful piece of metallic artwork and I recommend it to anyone looking for a 4-2-1 manifold.
Video/audio in a few days and then you all can really know how it sounds

Very nice! Looks like they still offer full bespoke shielding. It isn’t as “full” for the 355 manifolds. I’m probably the last person with 355 manifolds they did full bespoke shielding.

 

Regarding cats… I would say it does give a lil more volume and F1 pitch as you move closer to straight pipes. I don’t have direct experience with 200 cell cats on the Scud, but going from 100 cell to straight pipes gave roughly 10-15% more volume and pitch. Not a whole lot, but it’s there.

I’m not sure what % increase from 200 cell to 100 cell cats would be, but Felix from Kline himself (I think he’s the owner) isn’t too favorable towards the 200 cells with his system. He tends to push 100 cell cats, hence you are more likely to see Youtubers running Kline with 100 cell cats. 200 cells are standardized in the industry and less problematic for CELs. Anything below needs a fooler or a tune. It’s more hassle.


Here is a part of an email exchange I had with Felix when I acquired my system in 2017.

The last was a response to a debate between 200 cell or 100 cell. I had already placed an order for 200 cell cats, but he convinced me to get 100 cell.

 

Here’s an old post from RichardCH who also ran Capristo headers + 100 cell cats + Kline Inconel on his Scud. I guess he ran 200 cell at one point.

Interesting Felix at Kline recommends scuderia manifolds actually and not his own manifold.

 

I noticed that when I read it again. It’s been a min. Kline manifolds were indeed available at the time.

*I already had Capristo manifolds installed before inquiring for Kline parts.

Tubi & Larini 4-2-1 manifolds were not on the market at the time. Capristo was the only 4-2-1 option. Or 430 challenge headers, which I wasn’t aware of at the time.

 

It is odd how it is so different, but it is. I assume different lengths and materials. One good example I remember well...when I had the un-valved SLine system, low rpms sounded awful. Like taking off from a start was embarrassing IMO. Freaking hated it one time while I was in traffic in California for like an hour. Every time I had to start accelerating again I couldn't help but think what the heck people were thinking of how ****ty and loud my car sounded. Haha. With the Kline inconel it is NOT that at all now. It sounds totally different and really nice and clean even from a start. Then this metallic ping starts to hit at around 2,200rpm and up and it's pure music. I find myself almost always driving 100% un-valved now and am so happy with the switch.

 

Has anyone tried Valvetronic’s titanium system? Seems like it might be raspier due to the titanium.

 

Is the Kline more silent than stock with valves closed ? I think I read that before... Does it connect to the stock hydraulic valve system, which open automatically on certain revs ?

 

I can't remember. Would have to hear side by side to compare, but I believe so. It's nice and quiet when closed.

Yes it connects to the stock lines.

 

On a Scud, muffler vs muffler, it is quieter than stock valves closed and open. You’d need to do header and cat mods to bring any volume back. It’s been a min since I’ve been in a stock Scud, but if it’s louder than stock after header and cats, not by much if any. Loud is not a concern on a Kline. Could be different on an F430, but I haven’t seen any clips to suggest it is loud.

 

With Fabspeed headers and stock all else , car is a tad louder with valves closed, and much louder with them open. It is really a riot past 5000 rpms. I am thinking of the Kline for weight savings mostly, but if it does not add noise, it could be a good choice ? Can I keep stock cats, or do I need cats too?

 

Ok, I finally have a sound clip for you all with the Larini manifold + inconel Kline 200 cell cats and exhaust.

More clips to come, I just wanted to get you something asap, literally was just at Pocono last night and clipped this this morning.
This is using the same setup that recorded my previous video, GoPro mounted in the cabin using the GoPro "mic mod". I got some audio using the DJI 2 mic externally as well but there's a lot of noise, I need to go through and clean that up still.

Hope you like it, I personally love the way it sounds and this setup is basically perfect in my opinion. 40lbs less than stock, less drone than stock, smoother than stock, has more high rpm scream than stock, and is even quieter than stock with the valves closed. Truly an improvement all around. Does it scream quite as intensely as some other setups I've seen with no cats, etc? No, but I find this setup to be much smoother and pleasant than practically all of the setups I've heard while still having 90% of that scream.

 

I would think he meant the challenge headers. The Scuderia headers have air-injection which need to be plugged,.

In case anyone was wondering, since we had pics above showing the Larani... here is the challenge headers

and after 4000 miles on the car, has a nice golden hue

Took the scud to one of the best sections of road in America today, the Hawk's Nest lookout at the border of NY and PA.
I put the GoPro in the engine bay. There were people along the outlook so I took it easy but at the end of the video I do a redline pull. Sounds incredible.




And here's the same road but video from inside the cabin, mounted to the windshield.

 

Had to reupload the videos, here are the latest links:

 

I've waited long enough that I think the price of cats+headers are significantly more than when I first starting looking into it. D'oh.
@gammi where did you order yours?

 

I ordered both the Larini manifold and Kline exhaust from Top End Motorsports. Just shoot them a text for a quote.
https://www.topendmotorsports.com/ferrari/f430/engine/exhaust/

Here's the page for the manifold direct from Larini. It's listed for $2k more there so I would assume there was a price increase and the price of Top End is outdated.
https://www.larinisystems.com/collection/ferrari/430-scuderia-gtc/larini-gt2-exhaust-manifolds-inco

Also I'll add I feel like the Larini manifold dropped my engine bay temps and the temps of the engine itself. Driving up in the mountains yesterday it was 60-65F so not cold but not hot and I was finding my coolant/oil temps were barely getting up to operating range, it was running abnormally cool.
