$1,301.07

Looking to unleash an additional 20 to 30 horsepower from your Cayenne Turbo? Want to improve spool-up times and help reduce turbo lag? Look no further! We are extremely excited to present our new 955 Cayenne 4" Hi-Flo™ catless downpipes! In addition to an intoxicating and exotic sound, these downpipes add significant power and virtually eliminate turbo lag, making the amazing Cayenne engine even more responsive!

Our Hi-Flo™ 4" Downpipes Feature:

- 100% hand crafted in the USA from premium 304 Stainless Steel - flanges and O2 bungs included!
- Water-jet cut 304 Stainless cat-back flanges, and CNC'd 304 Stainless V-Band flanges.
- 100% TIG welded, argon back-purged.
- Lifetime warranty against any manufacturing defects given to original owner.
- We do NOT grind/polish our welds as some other manufacturers do. Grinding welds compromises the strength of the weld, and can lead to weld failure! Especially critical in applications exposed to temperatures in excess of 1200°F. Such temperatures will also rapidly deteriorate the polished finish.


More information on our Ceramic Coatings

The coatings we offer are capable of withstanding temperatures of 2000°F. In addition they offer excellent chemical and corrosion resistance and possesses excellent thermal barrier characteristics, providing a dramatic reduction in radiated heat. This means reduced under-hood temperatures, accelerated exhaust gas velocity and a longer life expectancy for the downpipes.

Ceramics stand above all other thermal barrier coatings currently being used in combustion chambers. Ceramics have characteristics shared by no other product, providing an unrivaled layer of thermal protection to piston tops, aluminum heads, stainless, iconel and titanium valves. Ceramics "move" heat, reducing detonation and increasing the effective oxidation of fuel. When polished, it provides a highly reflective surface that further aids in improved flame travel. Unlike previous ceramic coatings, ours is not subject to cracking and flaking, which can lead to extensive engine damage. In fact, Ceramic coatings actually strengthen the coated part. The cured "Cermet" provides a cap of material that can withstand far more heat. During testing when sufficient heat was applied to a piston to melt the aluminum, the Ceramic did not melt, rather it held the softer aluminum together.

The Satin Ceramic Exhaust Coatings we offer are the most advanced exhaust system coatings available. They are a very durable ceramic-reinforced coating available in various shades. When properly applied, it becomes the most effective thermal barrier coating available, increasing performance while extending component life, and has been tested to over 2000°F without lifting, cracking or flaking


2000°F coatings are available in the following colors:
-Satin Silver
-Satin Black

Those are VERY nice!! Tops on my list of mods as I am not subject to emissions.

How about a set of headers to match?

 

We have not developed headers for the 955 yet Is there much interest in this?

 

I too would be interested in headers for a 955 Turbo S

Who manufactures the catalysts you use in your "catted" turbo downpipes and what is their cfm rating?

 

The cats are from magnaflow. Sadly, they don't like to give out their cfm ratings on them.

 

Will these work in the 957 as well?

 

Yes sir!

 

Bump!
