Ar Design - 535i / 535xi 3" Hi-Flo Downpipes w/Race Cats

ar design II · 11-15-2012, 04:30 PM

Our Hi-Flo™ 3" Downpipes w/Race Cats Feature:

3" tubing until cat-back flange.
100% hand crafted in the USA from premium 304 stainless steel (cats are made from 409 Stainless) - flanges and O2 bungs included!
Water-jet cut 304 Stainless cat-back flanges, and CNC'd 304 Stainless V-Band flanges.
Magnaflow 3" metal substrate race cats
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 washers included.
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 1600°F. Such temperatures will also rapidly deteriorate the polished finish.
NO CEL on pre 29.2 Progman cars - post 29.2/MSD81 testing is currently being completed, but due to the superior quality of the cats, we expect no issues.

How much rwhp will you see on a tuned 535 with the catted DP's?

Will they pass smog in CA?
