We are extremely excited to present our new 535i / 535xi 3" Hi-Flo™ catless
downpipes! The only TRUE 3" downpipes currently on the market! In
addition to an intoxicating and exotic sound, these downpipes add
significant power and virtually eliminate turbo lag, making the fabled
N54 engine even more responsive!
Our Hi-Flo™ 3" Catless Downpipes Feature:
- The only TRUE 3" catless downpipes currently on the market! 3"
tubing until cat-back flange - all systems currently on the
market reduce to 2.5" much closer to the turbocharger.
- 100% Hand Crafted in the USA - not China - 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.
- Set of our exclusive bomb-proof exhaust gaskets included.
- Grade 10.9 Metric Hardware(145,000PSI tensile strength, C32-C39
Rockwell, Zinc Plated), and Nord-Lock positive locking re-usable
- Factory location O2 bungs
- Available with a 2000° F ceramic coating. Coatings come with a 3 year warranty against corrosion and rust to original owner.
- 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° coatings are available in the following colors:
|Satin Grey Ice
||Satin Fresh Blast
