We are extremely excited to present our 1M 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 washers included.

* Factory location O2 bungs

* Available with a 2000Ã?Â° F ceramic coating. Coatings come with a 3 year warranty against corrosion and rust to original owner.(HPA highly recommend this to reduce both under hood temperatures and increase the longevity of the DP's)

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

$836.07

***Optional ceramic coating $159***
