NEW 355 CAPRISTO EXHAUST SYSTEM, NO MORE Y PIPE

Hi Guys, here is a video of the new 355 exhaust system, which makes 22 hp more! No more Y pipe design to cause false 02 sensor readings & header problems caused by air getting sucked back into the muffler due to the OEM muffler design.

Any questions call 360 410 1949

Look at the Dyno Jet numbers & turn up your speakers!

Also comes with an optional remote controller that you can program at what RPM you want the bypass valves to open!
There is nothing like this on the market. 309 ANTI CORROSION STAINLESS STEEL, 5 YEAR WARRANTY. Enjoy!

The OEM bypass valve is a disaster from a design point, it makes the 355 sound great, but it is contributing to allot of the 355 exhaust problems. This new Capristo system is designed to replace the cause of the problem, removal of the OEM exhaust system design.

With respect to the remote control, it is a small black box that operates on vacuum, you can program when the valves open & close depending on how many mill bar of vacuum is selected. You can program it to open at a certain RPM range, which allows for maximum torque at low RPM & maximum HP at high RPM. We have been offering it to the Porsche Cayman users for some time now with great results. It also works well for weekend track events as it allows complete bypass of the mufflers with a flick of a key fob if desired.

Capristo ALSO offers a by pass valve kit for the OEM exhaust system design that will stop engine damage that happens when the bypass does not open, Capristo’s version goes into default bypass if something goes wrong with a vacuum line, instead of staying closed, which is what happens to the OEM version thus destroying engines.

The 550 Maranello has the same issue at high RPM, if the bypass valves do not open, it will cause engine damage. In any event, I just want to make fellow Ferrari owners be aware. A 355 owner that has an OEM version exhaust system or one derived from the OEM design, rather it be Tubi, X-OST, ANSA etc. need to be aware of the issues with respect to the OEM design.

Over the years of being F chat’s first & longest running sponsor, I have always been known for addressing arising issues with respect to certain model Ferrari’s, more so before when I was not as busy & had more time to spend on F chat. This is just a heads up to us fellow owners; I just do not have the time to be here posting here like I did 4-5 years ago as I have so much going on. Any questions, please call me at 360 410 1949 & I will make the time to talk to any fellow Ferrari owner about their individual concerns or questions.

Forza Ferrari!

 

Capristo make a system for the 2.7 & 5.2, you must specify when ordering the complete system.
The OEM bypass valve mod works on all OEM 355 valves.

 

The best retro fit recommendation in my opinion would be to install the Capristo version bypass valve, this way, if the vacuum line fails you will not be subjecting you engine to excessive heat at high RPM before you realize what has happened.

This new exhaust system design came up due to many hours of Dyno testing, probes were inserted in different areas of a OEM exhaust system (Y pipe, headers, muffler) verifying that there is, air coming in from the exhaust tips under certain conditions.

Consequently any system derived from the OEM design could have the same issues, some less, some more depending on the internal design of the muffler.

 

The 22 hp rear wheel difference is between OEM & the new Capristo 355 unit.
As far as the single Capristo bypass valve with solenoid/-electro valve, it sells for $ 995.00 & can be retro fited on any 355 system that uses the OEM Y pipe. Below is a pic of the valve.

I will also try to post a few pics in the next few days that show how the actual exhaust flows through the OEM system & how it differs to the new 355 Capristo system.

Thanks guys, I will get a copy of the dyno sheet & post it from Capristo.

I will have to do another post that shows what happens to the INCOMING air from the tail pipe tips once the OEM bypass valve opens, some of you will be very surprised!

The new system is really not what we are used to calling a stage 1, 2, or 3. I guess its a cross between a 1 1/2-2 & a 4 at WOT

Most of the Hp will be in the high RPM as the Cparisto bypass valves are working in that 5000 RPM range & up. Keep in mind also that the low end torque is also good due to this new design as the valves are still kept closed or partially closed bellow 5000 RPM. I believe they start to open slightly at 3500-3800 RPM. I will confirm on that to be sure.

Below are a pics of the 5.2 Capristo system, the 2.7 version inlet tubes are slightly different.
