Kriessegg Install Prep 348

Thats a lovely looking exhaust!

If they machined the surfaces spot on, then you may not have to use anything.

But if they supplied the tube of exhaust paste, then thats what I would use.

On the majority of turbo to exhaust connections on our machines underground, we dont use ANY gaskets or exhaust paste at all. They always seal up, because the manufacturer machines the surfaces perfectly flat.

Probably flatter than glass.

I would just use the paste man, thats probably what they will tell you its in the kit for when they email you back.

 

Wow, on bypass that is completely skipping the muffler can!

I am no expert, but where it comes out from the muffler to the exit pipe, (the short section), I would have thought they would have a smoother transition, rather than meeting at almost 90 degrees to the exit pipe.

 

Thats why those Kriessegg exhausts SCREAM!

Have heard many on Youtube, man o man they sound great!!

 

I also found that angle odd especially when you look at some of the other nice, smooth bends and how they go out of their way to give their 355 5.2 Y-pipe nice sweeping bends.
It seems Kreissieg has a good reputation but the finish on their products appears to lack attention to detail compared to Tubi and some others (even though they go for Tubi prices). Their website isn't too great either.

Having said that, their pipes certainly sound good.

 

Hello.

Those are actually high-temp grease for the installer to apply on 4 bolts that secures the valve.
The valve unit gets extremely hot, so it is for preventing cease on the bolts.

We haven't got any email from you about missing installation manual.
If you can provide us your serial number on the muffler, we will email you installation manual.
Please email me to [email protected]
Thank you!

Actually if all the gas bypasses, it does not sound the way we want.
That's not much different than just straight pipe which never sounds good.

Our piping connection also have "fin" inside to control the gas flow.
The connection angle is meant to be that way to create unique resonances.
This is one of our own know-hows to create unique F1 sound.

 

There is slight movement because of below reasons.

The valve unit gets extremely hot especially on MR cars where valve is located near to the exhaust port.
The butterfly often gets red glowing hot.
The valve unit has to have some clearance due to heat difference(thermal expansion) with flanges.
FYI some Ferrari OEM valves are same way too.

Once you bolt it up, it does not leak because the surface is perfectly machined.

 

Well there ya go.

 

By pass valve? Questions. What activates the bypass valve on this set up? When does it open? I assume the standard 348 does not have a by pass as standard, correct? So why is one included? is the by pass valve included in other after market systems? Is it the same as that of the 355s? Did the 355 set up inspire the use of a by pass valve in the 348 system?
That system looks a great bit of kit, well built and engineered.

 

Most of our exhaust system equipped with the valve(s) to control the loudness between F1 mode and silent mode.

The valve is controlled by either wired switch or wireless remote(optional).

 

So the by pass valve was clearly influenced by the 355s then.
Does anyone know what other 348 systems have a by pass valve? Capristos maybe? Which after market systems was the first to introduce a by pass valve for the 348? I am betting it was the capristo company.
Any video sound bites of the system changing tones when on the road?

 

I love the sound

 

I would like to thank you for coming on FChat and answering questions asked by the retail purchaser.

This means alot for a manufacturer to reach out in a public forum.

It shows to me atleast, that Kreissieg is very much interested in providing great customer interface.

Look forward to future comments, suggestions, and assistance.

 

Funny, I just copied and pasted your spelling without checking...

 

Thank you for the explanation, shows you what I know.
