430 Whom makes the best F430 exhaust headers sound wise ?

Yes that is not the same. A single pipe with a crush gasket and two BOLTS. Not 4 in a collector held together with springs.

There are literally endless posts about people having leaks there on the supersprints and having to replace the gaskets. The company owner himself said as much.

Many have just welded the tubes into the collector.

If that's not possible in your fantasy world, fine with me.

 

And those two bolts are torqued against a spring, not a rigid surface.

Any joint type can leak when not installed correctly, poor quality control, etc. You conveniently ignored the people posting who have had them on for years without leaking. I'll stay in the "fantasy" world with Ferrari, Supersprint, etc. You can believe what you want with your internet research on issues that infallible DIY'ers are having and what you think from looking at pictures.

 

Lmao, yes two bolts compressing two heavy springs that can literally crush the gasket in half is more clamp load than 4 gaskets and light springs in tension.

Is that not obvious to you?

Once again, the owner of Supersprint called them a maintenance item but you say they can't leak. Makes perfect sense.

 

As promised, a few pics of the finished inconel shielding from ATP. Very pleased with the results for the cost - should insulate nicely! And there is still plenty of flexibility to it that will make installing all of the header nuts easy enough (in addition to the cutouts they made).

Never said they can't leak. Since you've devolved to putting words in my mouth in your disbelief that this type of connection has any sort of durability I'll leave you be with a reminder that Supersprint knows more than you about how to design and manufacture an exhaust, and they're still selling this connection type across multiple product lines. If it was as problematic as you think based on your dabbling in car forums they simply would have pulled it to protect their reputation but they have not. Someone is not telling the truth here and it's probably not the company with decades of exhaust R&D under their belts.

 

Oh sorry I didn't quote your exact posts. Better?

And if you trust Supersprint then you trust when they say the gaskets and springs require maintenance. Just what I want to do is remove my entire exhaust system to replace collector gaskets and springs.

If that's what you want have at it but don't pretend I'm putting words in your mouth.

 

Like I said you've devolved the conversation and in your childish ways now insist that "proven design" and "nothing to worry about leaking" means "never leaks'. If I'd said a welded collector is a proven design that you don't have to worry leaks you probably would have accepted that even though they fatigue, have poor weld quality, etc., which furthers my point that you're just being obtuse.

 

I stated- "I would prefer if it wasn't a slip type collector as any tiny exhaust leak there would skew o2 sensor reading" and you responded with it nothing to worry about leaking and it's a proven design.

Now you're saying that doesn't mean they "never leak". Ok, then I guess we are in agreement despite my obtuseness right? GFY

 

With a fun/weekend car I find it more enjoyable to have the power higher up the rev range. I find I'm naturally short shifting at the moment.

In my daily driver I'm happier with good mid range.

 

A. You sound like an child.

B. Supersprint would not bother with this connection type if it was half as troublesome as you and the infinite wisdom gathered from your keyboard and the Internet would have you believe.

C. Apologies to everyone else whose time was wasted on this tangent. I'm done here.

 

Of course I sound like "an child", I'm stupid and unwilling to learn remember?

For the hundreth time, Supersprint themselves said they are a maintenance item which means they eventually leak and have to be replaced. That is the exact reason I stated I would prefer it was not a slip fit collector.

You seem to feel you're the only one entitled to an opinion so thanks for sharing yours.

 

On the Supersprint joints: one version of the M5 manifolds had a slip joint (no gasket). The F430 manifolds have the sane type of joint as the Ferrari manifold to catalyst joint i.e. a conical, tapered gasket. Those type don't leak or create the noises mentioned on the M5 thread, but the gaskets will require eventual replacement - like the OEM cat joint gaskets.

A slip joint typically does allow some gas past until the exhaust is up to operating temperature and the tolerances reduce. Not sure I'd want it on a road car.

 

Grasping at straws I see. Yes, the "an" was an artifact because I initially typed something else. You got me.

I never said you were stupid or unwilling to learn, though you are proving it with each new post. I said I would leave this thread but not if you continue to lie and put words in mouth. Just stop.

 

It isn't exactly the same. The gasket is floating on the tube, not crushed between two fixed points. (and has much less clamping force over a much larger area).

Many of the responses were speaking of that same design.

 

You said "my obtuseness". Do you not know the definition of the words you use because once again I'm not lying or putting words in your mouth.

 

The definition of "obtuseness":

the quality of being stupid and slow to understand, or unwilling to try to understand

In the context of how I used it, e.g. your disbelief that Supersprint knows how to design headers, you should have picked up on what was meant, instead of assuming the worst and ironically continuing to be obtuse.

So yes, I do know the definition of the words I use, and more importantly, have a nuanced grasp of the context in which they are used. Hopefully with that cleared up, you can leave this be like I will again try to do.

 

Guys, you know what they say about arguing on the internet, right? Can we get this thread back on topic?

 

Sorry Joe I'm just stupid and slow. Anyway, yes I'm still in preference of the Capristo in terms of overall design though they are expensive.

The larini's with heat shielding look nice as well.

As far as 4-1 and 4-2-1 design, it's often thought that 4-1 delivers more high rpm power at the loss of midrange but a properly designed 4-2-1 will make the same high rpm power while still bolstering the midrange.

 

On topic, for anyone curious about the spring clamping force required on the Supersprints vs the bolt/spring connection on the 360, the torque spec on the 360 bolt/spring assembly is a mere 16 Nm to effectively seal the crush gasket.

 

Rocking the super sprint on my 360 and not one problem

 

Your thoughts on the Larini 4-2-1 design versus Capristo's 4-2-1 design?

@ttforcefed is the only person I know with Larini headers for 430/Scud.

 

And 100% not comparable because it's not the same design but lets continue to ignore this like a complete idiot. AGAIN two BOLTS compressing heavy springs over a single gasket that's compressed between two fixed points.

Compared to, no bolts, springs in tension across 4 gasketed points (with gaskets floating and not fixed between two points)

I have zero concern with the Ferrari crush gasket and two bolts/springs. I'm literally building a set of headers with them right now.

 

Hi Ken! I'm not entirely sure on that. I feel many of the Larini photos are not real/pulled from their design software.

If going off of only photo's I've seen I prefer the Capristo design. ( but again, feel I've not seen real photos of Larini)

 

Since a month ago? Good to hear. Nice Eldorado Brougham btw.
