Jlevi SW | AR Design 3" High Flow Downpipes for the N54

[SV Concepts III]

We are proud to carry the highly regarded AR Design 3" High Flow Downpipes for the N54.

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 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 1200°F. Such temperatures will also rapidly deteriorate the polished finish.
