How To Get That F1 Sound

What have others been using these days for heat management on aftermarket headers? I realize you can always go the way of using HP header armor, but at the expensive of some time and effort fitting it the way you want it and making it look clean which takes time. https://www.heatshieldproducts.com/header-armor

Obviously ceramic coating is an option as well.

Buy a scuderia ..they have a great best of all modern V8.s

 

It sounds great. Congrats!

 

Its just a shame they are so rare for F430's, and priced like unicorn horns when you can find them...

 

You can buy Kriessiegs brand new direct from a reseller in Japan for reasonable prices.

 

My Kline inconel catback and 200 cell cats arrived finally, I'll be installing this week.
The Larini manifold that I ordered still hasn't arrived so I'll be installing that separately.

That means I'll be able to provide comparison videos, one with stock manifold + Kline and one with Larini + Kline.

Personally I care much more about the tone than the volume. I think the 200 cell cats will be right for me, it shouldn't really be much louder than stock, possibly even slightly quieter. But the tone will be much better from the X-pipe the Kline has.

 

Challenge headers and X-Pipe will do it! Its very loud though!

 

Install a small displacement turbo v6 with dual 3 into one into one full open exhaust to get a F1 sound..

 

forgot I made this clip - stainless valved s-line, rest is factory scud

 

Finally got a video of my inconel kline exhaust (with oem manifold still)

 

**hardly scientific analysis ahead**
I'm sure the different mics, placements, etc make a difference but I was curious what running those two samples through a frequency analyzer would report compared to what I'm hearing through my headphones.... I think it matched?

I tried to freeze-frame them at 3rd gear 8000rpm (I'd say +/- 200)

Overlay suggests the S-line unit has a bit more high end (and/or the Kline sample's mic didn't capture it all)

for completeness I used a bumper mounted Shure SM57 and a Zoom H6e to record the S-line sample

also a real v10 at redline at the bottom courtesy of very old YT footage for comparison

My mic was placed inside the cabin which I think is going to give quite a different response than outside unfortunately.
Also there's a foam cover over my mic which has the effect of reducing wind noise but also reduces high frequencies.

I appreciate the effort though

Ah yeah, I have a big foam wind guard too forgot about that. Kind of like dyno comparisons need same gear on same day sort of tests to be definitive.
I’m looking forward to hearing your impressions on the Larini headers!

 

@gammi did you ever install those Larini headers? How was quality/shipping time/etc

 

Sorry for the delay. The headers are finally installed. I think everyone should consider replacing their headers as preventative maintenance since the OEM one is prone to warping. Quality is excellent. Shipping was slow, took a couple weeks longer than the Kline exhaust parts, I think it took almost 3 months if I remember correctly.

As for sound, this is just going off of memory but I feel like there's less drone now. With the OEM manifold + Kline cats and exhaust I didn't like leaving the valve always open because it would drone at lower RPM. So I would leave it in the default setting where it opens under load. Now with the Larini I can leave it always open just fine. Also I noticed with the OEM manifold there was a faint metallic pinging at idle, that's now gone with the Larini, must have something to do with different shaped/thickness metals resonating differently, whatever metallic engine sound that was carrying through the OEM manifold is no longer carrying through.

I think it's a bit of a trade-off though. There's less drone and the sound did get smoother/richer and not necessarily deeper, if that makes sense, which I feel is a great thing. But it did lose a touch of the high rpm scream. So ultimately I feel the sound is "better" now in the sense it's more well rounded but if you're going for ultimate scream, this isn't the choice. Then again, you probably wouldn't be getting the Kline if all you wanted was scream anyway, so I'd say the Larini matches well with the intent of this whole setup, close enough to "F1 scream" without being harsh or droning.

But again, this is just going by memory. Maybe the actual clips will say otherwise. I'll be tracking the car at Pocono Raceway in a week and will be getting some video using a DJI wireless mic in the engine bay (near the back where the grille vents are) which should produce some great sound. I'll also try to get a clip with the camera mounted the same way as my previous clip (in the cockpit, suctioned to the rear glass) to do exact before and after comparisons.

Also this could just be because I've been driving my slower (not by a lot) Audi RS5 lately but my first drive back in the Scud with the Larini headers I was actually caught off guard with how quickly it accelerated. I was on a backroad in 2nd gear, stepped on it and redline came up VERY quickly. Again, it's just seat of the pants feel so not scientific but it does feel very rev happy and quicker now with the Larini. I was simply startled by how quickly I found myself at redline, which implied to me that something had changed, otherwise it shouldn't have been such a surprise as someone who's put 1k miles on this car in the last 6mo.

 

Thanks for the update! I haven’t had good luck with the wireless mics (RODE gen1) due to clipping and/or the mic sound floor but I haven’t used the new DJI or other 32bit ones.

I’m very curious on the “touch less high rpm scream” with the Larini. You’re the only example I know of who did the 4-2-1 and stepped primary headers /after/ cats+mufflers.

I assumed adding steps (vs OEM) would’ve dialed up the pitch noticeably. Hmmm.

 

It's the DJI 2 so it can actually record right to the mic's internal storage. It also has a 3.5mm jack to connect a better mic if needed.
I'll be recording at Pocono with the GoPro mic in the cabin and the DJI in the engine bay.

It's probably best to reserve judgement until I post video/audio in a week. I very well could be misjudging it by memory.
Imagine going to a hardware store to look at a paint color, not bringing a sample home with you, and then trying to visualize that exact color again in your home. It's hard. Same for audio.

 

There is a new 4-2-1 F430/Scud header in the market.

Reading this thread makes a decision even harder

Great info.

For my stradale I'm considering:

Cap headers
No cats
Kline or Kreissegg valved muffler

Thoughts?

 

You can get back the scream and then some with 100 cells or straight pipes.

 

Tubi headers to keep it 4-2-1 and best header wrap on the market
Kline inconel test pipes if you don't want cats
Kline inconel valved muffler

 

Capristo blanket wrap is most likely an inferior solution to Tubi’s stamped metal shields, but it still does a decent job of keeping heat from surroundings.


If you desperately want a Capristo header design, but arent a fan of the blankets, I’d either ask to buy them without blankets for a discount (perhaps $1500-2000 less). Or buy them as is and sell the blankets here. There are lots of people who still want to purchase Capristo blankets, but Capristo does not sell the blankets separately from their headers. Many have tried to buy them with no luck, so there is a market for them.

I’d then send the Capristo headers to a bespoke wrap specialist like Thermo-Met (UK) for the ultimate F1 grade “bespoke” heat wrap. This is the highest heat wrap level on the market and goes beyond keeping surrounding cool. Each pipe is tightly insulated with a special material held together by bespoke shielding to keep as much of the heat in the manifolds as possible. Heat speeds up exhaust gases, which translates into more power.


Kline offers a bespoke heat wrap option as well.




Tubi heat shields are good, but they are just mass stamped and crimped. There’s no insulation between the manifold and the heat shield. It is about as good as an OE header for heat management and looks the part.



Lettieri is a former head Tubi engineer who branched off to start his own company. Partly the reason wby alot of their products look similar to Tubis. However, they might be chasing a little more performance and quality than Tubi. I would look into them. They also offer stamp shielding (like Tubi) or bespoke shielding. Stamp shields is for manufacturers to offer quick manufacturing solutions so products can arrive to customers quicker. Bespoke shielding takes alot more time.


Larini used to offer a very bespoke shielding, but I think they only offer partial now to speed up deliveries. Not sure if they have an offering for the 360.
