Introducing SuperSprint's 360 Modena Full Modular Exhaust System !

any update on this?

 

Bump. Chris, I can't let you do all the bumping in this thread

 

Are the heat shields mounted to the car's sub frame ( at the engine mounts) ?

 

New pictures of the 360 headers will come soon.
A small correction, on the 355 the heatshields are mounted on the chassis, on the 360 instead they are on the headers!


As you can see the shields are smaller and strategically positioned thick, mirror-finish curved plates.
As the full system is much more free-flowing there's already less heat diffused by the headers, there's no need for a full wrap-around heat shields.
The mirror finish allow a better heat reflection, especially the infrared and visibile radiant heat.

 

============================================
Matt and all
It is Joe fabiani President of Fabspeed Motorsport USA. I design, Dynotest and verify all exhaust and air intake systems at my company. I am an expert in exhaust and airintake systems and performance tuning for Exotic cars.

MATT- you mentioned Fabspeed my company incorrectly in this thread and also made several major factual errors and incorrect assumptions on exhaust system function and design. Therefore I am not highjacking your thread. I am defending my company and clearing up many inaccurate statements.

#1 Fabspeed Ferrari 355 and 360 North American USA headers have optional AIR INjection tubes for emissions compliance in terms of a visual inspection only. The air-injection tubes were designed by Ferrari SPA for the North American USA market and are there as the engineers want the extra O2 injected for an immediate fast "LITE off" of the catalytic converter substrate for cleaner Cold Start emissions only. Basically, for approximately 30+ seconds air at Cold Start is injected to make the catalytic converters come up to operating temperature fast so they scrub the exhaust and then the air injection pump is TURNED off for the remainder of the driving cycle.

Ferrari as well as Porsche and other domestic and international OEMs do this for USA emissions laws.

MATT- you are therefore incorrect as stating Fabspeed AIR injection tubes are employed by Fabspeed to trick Check Engine Lights. Q.E.D.

FYI- on my 2003 360 Spider USA I hooked up the AIR tubes and have NO CEL lights. For Ferrari RACERS and Drivers Education Ferrari owners all our AIR injection tubes are easily removable and completely optional depending on what the owner wants to do with his/her car. Ferrari cars dont know if air injection tubes are hooked up. Fabspeed always builds the best systems.

#2 MATT- you mention above "SuperSprint headers are mounted with HJS 1st grade FIA approved 100 CPSI metallic racing catalytic converters which allow a CEL free usage".
MATT- this is a completely BOGUS made up statement by you and completely false.

Fabspeed USA is HJS Germany's largest volume purchaser of catalytic converters for all of North and South America. #1 There is no HJS 1st grade catalytic converter. HJS German does not under any circumstances have Grade #1 or any other grades. There are NO HJS 2nds or Blems. HJS make the worlds best catalytic converters that dont fail and all Ferrari owners should demand these for the cars when they want aftermarket sports racings catalytic converters.

Matt mentioned above these phrases: FIA certified and headers with cats:>
#2 the FIA does not certify any catalytic converter or exhaust products. FIA is an acronym for a French based racing sanctioning body "Federation Internationale de L’Automobile". You made this all BS up for credibility. Do you know Jean Todt?
#3 You state that Supersprint headers are mounted with HJS catalytic converter- WRONG again- aftermarket race quality performance headers eliminate any pre-catalytic converters and rely solely on downstream sports racing catalytic converters as shown in your Supersprint photo. Know and understand your products and pictures before you post for COL. Why does the Supersprint Ferrari headers have multiple O2 bungs all over the primary tubes?

#4 MATT- you mention the added engineering value of spring loaded Merge collectors and make several incorrect assumptions and also state the Supersprint doesnt use spring merge collectors on the Ferrari V12 models as heat is further down the pipes and durabilty is therefore not compromised. I will be brief here.
HEAT on an exhaust system ONLY travels with the exhaust path one way as the exhaust gets to operating temperature. The exhaust is at the highest temperature at the exhaust ports and cools down dramtically as it travels the length of the exhaust system to the exhaust outlets or tips.

The Ferrari catalytic converters are downstream on these cars. Therefore the spring attached merge collectors offer no benefit nor extra value in terms of performance or longevity. Ferrrai V8 aftermarket headers are even further from the catalytic converters than V12 cars. You mention that Ferrari V12 car headers dont require springs but V8 Ferrari cars should have the springs. I compeltely disagree. 1st IMHO none of these Ferrari V8 or V12 cars need springs but the V12 engines are buried and spring loaded collectors would make installation easiier if the cars needed headers.

Fabspeed and other quality headers dont have spring loaded collectors for many reasons. #1 there is NO engineering advantage for employing spring loaded collectors.
#2 Slip jointed V8 header collectors-- offer 8 areas for EXHAUST leakage if the pipes dont seal correctly. An exhaust leak on a late model Ferrari or any other OBD2 car can easily trigger a CEL light and allow exhaust gases to pass into the cockpit or into the engine bay. Fully welded headers dont allow any leakages of any kind. Fabspeed has been making exhaust headers for 15 years with no failures. Supersprint for many many years offered fully welded headers.............I think someone thinks the springs are SO SEXY- so racy!

MATT- you show a Mercerdes C 63 AMG with fully exploded slip jointed headers. The REAL REASON that these headers and many other headers are in PIECES is that on extremely difficult header installations slip jointed headers make installation easier and faster for an installer in "jammed engine bays". Fabspeed is a KLEEMAN dealer installer and installing headers is very diffucult on these cars..............multiple piece part headers dont require the engine to be pulled or raised to fit.

Lastly- Fabspeed ONLY designs and releases exhaust systems and parts that make SOLID power on exotic cars. Everything is Dyno proven and street and race track tested.

WHAT happened BMP Design Supersprints long-time USA sales agent? I bought many headers for BMW and other cars from them>


I just wanted to make sure everyone has the right information to make a good decision for their Ferrari!

 

I'll just give a brief explanation why we use the spring loaded collectors.
There are two main reasons:

1) Thermal expansions: as you may know Aisi 304 stainless steel has a consistent thermal expansion factor, and the pipes tends to extend along their axis. As in the 4 into 1 and 5 into 1 (M5 E60) the primary pipes follow very different paths but with the same lenght, if the header is all welded there would be critical tensions (both on the collectors and on the flanges) when the pipe that has a "straight" path push (the farthest cylinder from the collector) and the one with the more curved path pull (or push less).
With our system the pipes are free to expand and the leakage are avoided by the springs system. Even in the case of a seal failure, thery are inexpensive and easy to replace.
Instead if a single piece header cracks, it has to be removed and welded. Also, leakage on the head flanges are more dangerous than some on the collectors, both becase of the position and because temperatures and pressures are higher.
We sell many systems in northern US and Europe where headers can go from -20 °C from cold to red hot during heavy use.

2) Ease of assembly: as said correctly by joefab, our headers are much easier to be fitted on cramped engine bays and less engine components need to be removed (usually none, just covers, sometimes the steering column on FWD cars)

On racing cars these factors are less importante because of the different use of the cars themselves and of the constant availability of specialized mechanics in the racing teams.

On V12 engine, which usualy group cylinders 3 by 3, the needs of a spring loaded collectors is less important because the pipes have less thermal expansion differences.

I'm sorry if someone felt attached or criticized but we stand by our way to do things.

One more thing, HJS DO offer different grades of catalytic converters, from FIA approved to cheaper units.

Sadly not even their best Euro 5 OBD cats can match the most recent and strict emission rules on some cars, but we're working on that. We have a direct relationship with this company and work toghether to do our best.

About the air injecting system, it's true that the idea of this is to reduce cold start emissions (this is also the reason why recent cars have the cats very, very close to the engine), but I think no country at the moment do this kind of inspection on private owned cars, am I right? So I don't really see the utility of this system on an aftermarket exhaust.

I'll reply more extensively if needed on Monday.
